" --append-system-prompt "You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.
General guidelines.
- When you execute commands, always save their logs to files for easier reading if the output becomes large.
- When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
- When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.
- When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps:
Step 1: List recent runs with timestamps using: gh run list --repo VisageDvachevsky/StoryGraph --branch issue-529-06f1ccc4da77 --limit 5 --json databaseId,conclusion,createdAt,headSha
Step 2: Verify runs are after the latest commit by checking timestamps and SHA
Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo VisageDvachevsky/StoryGraph --log > ci-logs/{workflow}-{run-id}.log
Step 4: Read each downloaded log file using Read tool to understand the actual failures
Step 5: Report findings with specific errors and line numbers from logs
This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR.
Note: If user says \"failing\" but tools show \"passing\", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy.
- When a code or log file has more than 1500 lines, read it in chunks of 1500 lines.
- When facing a complex problem, do as much tracing as possible and turn on all verbose modes.
- When you create debug, test, or example/experiment scripts for fixing, always keep them in an examples and/or experiments folders so you can reuse them later.
- When testing your assumptions, use the experiment scripts, and add it to experiments folder.
- When your experiments can show real world use case of the software, add it to examples folder.
- When you face something extremely hard, use divide and conquer — it always helps.
Initial research.
- When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality.
- When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs.
- When you read issue, read all details and comments thoroughly.
- When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, use WebFetch tool (or fetch tool) to download the image first, then use Read tool to view and analyze it. IMPORTANT: Before reading downloaded images with the Read tool, verify the file is a valid image (not HTML). Use a CLI tool like 'file' command to check the actual file format. Reading corrupted or non-image files (like GitHub's HTML 404 pages saved as .png) can cause \"Could not process image\" errors and may crash the AI solver process. If the file command shows \"HTML\" or \"text\", the download failed and you should retry or skip the image.
- When you need issue details, use gh issue view https://github.com/VisageDvachevsky/StoryGraph/issues/529.
- When you need related code, use gh search code --owner VisageDvachevsky [keywords].
- When you need repo context, read files in your working directory.
- When you study related work, study the most recent related pull requests.
- When issue is not defined enough, write a comment to ask clarifying questions.
- When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication.
- When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed.
- When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default.
- When you need comments on a pull request, note that GitHub has THREE different comment types with different API endpoints:
1. PR review comments (inline code comments): gh api repos/VisageDvachevsky/StoryGraph/pulls/684/comments --paginate
2. PR conversation comments (general discussion): gh api repos/VisageDvachevsky/StoryGraph/issues/684/comments --paginate
3. PR reviews (approve/request changes): gh api repos/VisageDvachevsky/StoryGraph/pulls/684/reviews --paginate
IMPORTANT: The command \"gh pr view --json comments\" ONLY returns conversation comments and misses review comments!
- When you need latest comments on issue, use gh api repos/VisageDvachevsky/StoryGraph/issues/529/comments --paginate.
Solution development and testing.
- When issue is solvable, implement code with tests.
- When implementing features, search for similar existing implementations in the codebase and use them as examples instead of implementing everything from scratch.
- When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request.
- When you test:
start from testing of small functions using separate scripts;
write unit tests with mocks for easy and quick start.
- When you test integrations, use existing framework.
- When you test solution draft, include automated checks in pr.
- When issue is unclear, write comment on issue asking questions.
- When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help.
- When you need human help, use gh pr comment 684 --body \"your message\" to comment on existing PR.
Preparing pull request.
- When you code, follow contributing guidelines.
- When you commit, write clear message.
- When you need examples of style, use gh pr list --repo VisageDvachevsky/StoryGraph --state merged --search [keywords].
- When you open pr, describe solution draft and include tests.
- When there is a package with version and GitHub Actions workflows for automatic release, update the version (or other necessary release trigger) in your pull request to prepare for next release.
- When you update existing pr 684, use gh pr edit to modify title and description.
- When you are about to commit or push code, ALWAYS run local CI checks first if they are available in contributing guidelines (like ruff check, mypy, eslint, etc.) to catch errors before pushing.
- When you finalize the pull request:
follow style from merged prs for code, title, and description,
make sure no uncommitted changes corresponding to the original requirements are left behind,
make sure the default branch is merged to the pull request's branch,
make sure all CI checks passing if they exist before you finish,
check for latest comments on the issue and pull request to ensure no recent feedback was missed,
double-check that all changes in the pull request answer to original requirements of the issue,
make sure no new new bugs are introduced in pull request by carefully reading gh pr diff,
make sure no previously existing features were removed without an explicit request from users via the issue description, issue comments, and/or pull request comments.
- When you finish implementation, use gh pr ready 684.
Workflow and collaboration.
- When you check branch, verify with git branch --show-current.
- When you push, push only to branch issue-529-06f1ccc4da77.
- When you finish, create a pull request from branch issue-529-06f1ccc4da77. (Note: PR 684 already exists, update it instead)
- When you organize workflow, use pull requests instead of direct merges to default branch (main or master).
- When you manage commits, preserve commit history for later analysis.
- When you contribute, keep repository history forward-moving with regular commits, pushes, and reverts if needed.
- When you face conflict that you cannot resolve yourself, ask for help.
- When you collaborate, respect branch protections by working only on issue-529-06f1ccc4da77.
- When you mention result, include pull request url or comment url.
- When you need to create pr, remember pr 684 already exists for this branch.
Self review.
- When you check your solution draft, run all tests locally.
- When you check your solution draft, verify git status shows a clean working tree with no uncommitted changes.
- When you compare with repo style, use gh pr diff [number].
- When you finalize, confirm code, tests, and description are consistent.
GitHub CLI command patterns.
- IMPORTANT: Always use --paginate flag when fetching lists from GitHub API to ensure all results are returned (GitHub returns max 30 per page by default).
- When listing PR review comments (inline code comments), use gh api repos/OWNER/REPO/pulls/NUMBER/comments --paginate.
- When listing PR conversation comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
- When listing PR reviews, use gh api repos/OWNER/REPO/pulls/NUMBER/reviews --paginate.
- When listing issue comments, use gh api repos/OWNER/REPO/issues/NUMBER/comments --paginate.
- When adding PR comment, use gh pr comment NUMBER --body \"text\" --repo OWNER/REPO.
- When adding issue comment, use gh issue comment NUMBER --body \"text\" --repo OWNER/REPO.
- When viewing PR details, use gh pr view NUMBER --repo OWNER/REPO.
- When filtering with jq, use gh api repos/\${owner}/\${repo}/pulls/\${prNumber}/comments --paginate --jq 'reverse | .[0:5]'.
Playwright MCP usage (browser automation via mcp__playwright__* tools).
- When you develop frontend web applications (HTML, CSS, JavaScript, React, Vue, Angular, etc.), use Playwright MCP tools to test the UI in a real browser.
- When WebFetch tool fails to retrieve expected content (e.g., returns empty content, JavaScript-rendered pages, or login-protected pages), use Playwright MCP tools (browser_navigate, browser_snapshot) as a fallback for web browsing.
- When you need to interact with dynamic web pages that require JavaScript execution, use Playwright MCP tools.
- When you need to visually verify how a web page looks or take screenshots, use browser_take_screenshot from Playwright MCP.
- When you need to fill forms, click buttons, or perform user interactions on web pages, use Playwright MCP tools (browser_click, browser_type, browser_fill_form).
- When you need to test responsive design or different viewport sizes, use browser_resize from Playwright MCP.
- When you finish using the browser, always close it with browser_close to free resources." | jq -c .)

// 100 objects\n\n BENCHMARK(\"Render scene with 100 objects\") {\n graph.render(renderer);\n };\n}\n```\n\n## Integration Tests\n\n### Full Workflow Tests\n\nIntegration tests verify complete workflows:\n\n```cpp\nTEST_CASE(\"Complete dialogue scene workflow\", \"[integration][scene]\")\n{\n SceneGraph graph;\n\n // Setup scene\n graph.setSceneId(\"intro\");\n graph.showBackground(\"park.png\");\n auto* char1 = graph.showCharacter(\"alice\", \"alice\", Position::Center);\n auto* dialogue = graph.showDialogue(\"Alice\", \"Hello!\");\n\n // Simulate game loop\n for (int i = 0; i < 60; ++i) {\n graph.update(1.0 / 60.0);\n graph.render(renderer);\n }\n\n // Verify state\n REQUIRE(char1->isVisible());\n REQUIRE(dialogue->isTypewriterComplete());\n\n // Test save/load\n auto state = graph.saveState();\n SceneGraph newGraph;\n newGraph.loadState(state);\n\n REQUIRE(newGraph.getSceneId() == \"intro\");\n}\n```\n\n### Integration Test Patterns\n\n1. **Setup realistic scenarios**\n2. **Test multiple components together**\n3. **Verify end-to-end behavior**\n4. **Test save/load cycles**\n5. **Verify error recovery**\n\n## Error Path Testing\n\nAlways test error conditions:\n\n```cpp\nTEST_CASE(\"Error handling\", \"[component][error]\")\n{\n Component component;\n\n SECTION(\"Invalid input\") {\n auto result = component.processInvalid();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Resource not found\") {\n auto result = component.loadNonexistent();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Out of bounds access\") {\n REQUIRE_THROWS(component.accessOutOfBounds());\n }\n}\n```\n\n## Best Practices\n\n### DO\n\n✓ Write tests for new features before implementation (TDD)\n✓ Test both happy paths and error paths\n✓ Use descriptive test names\n✓ Keep tests focused and atomic\n✓ Test edge cases and boundary conditions\n✓ Use appropriate tags for filtering\n✓ Clean up resources in tests\n✓ Test thread safety for concurrent components\n\n### DON'T\n\n✗ Don't write tests that depend on external resources\n✗ Don't write tests that depend on execution order\n✗ Don't ignore intermittent failures\n✗ Don't test implementation details\n✗ Don't write overly complex test logic\n✗ Don't skip error path testing\n\n## Continuous Integration\n\nAll tests run automatically on:\n- Pull requests\n- Pushes to `main`\n- Multiple platforms (Linux, Windows, macOS)\n- Multiple compilers (GCC, Clang, MSVC)\n- Multiple build types (Debug, Release)\n\nSee `.github/workflows/ci.yml` and `.github/workflows/coverage.yml` for details.\n\n## References\n\n- [Catch2 Documentation](https://github.com/catchorg/Catch2/blob/devel/docs/Readme.md)\n- [CONTRIBUTING.md](../CONTRIBUTING.md) - General contribution guidelines\n- [Issue #179](https://github.com/VisageDvachevsky/StoryGraph/issues/179) - Test coverage audit\n","numLines":444,"startLine":1,"totalLines":444}}}

// 100 objects\n\n BENCHMARK(\"Render scene with 100 objects\") {\n graph.render(renderer);\n };\n}\n```\n\n## Integration Tests\n\n### Full Workflow Tests\n\nIntegration tests verify complete workflows:\n\n```cpp\nTEST_CASE(\"Complete dialogue scene workflow\", \"[integration][scene]\")\n{\n SceneGraph graph;\n\n // Setup scene\n graph.setSceneId(\"intro\");\n graph.showBackground(\"park.png\");\n auto* char1 = graph.showCharacter(\"alice\", \"alice\", Position::Center);\n auto* dialogue = graph.showDialogue(\"Alice\", \"Hello!\");\n\n // Simulate game loop\n for (int i = 0; i < 60; ++i) {\n graph.update(1.0 / 60.0);\n graph.render(renderer);\n }\n\n // Verify state\n REQUIRE(char1->isVisible());\n REQUIRE(dialogue->isTypewriterComplete());\n\n // Test save/load\n auto state = graph.saveState();\n SceneGraph newGraph;\n newGraph.loadState(state);\n\n REQUIRE(newGraph.getSceneId() == \"intro\");\n}\n```\n\n### Integration Test Patterns\n\n1. **Setup realistic scenarios**\n2. **Test multiple components together**\n3. **Verify end-to-end behavior**\n4. **Test save/load cycles**\n5. **Verify error recovery**\n\n## Error Path Testing\n\nAlways test error conditions:\n\n```cpp\nTEST_CASE(\"Error handling\", \"[component][error]\")\n{\n Component component;\n\n SECTION(\"Invalid input\") {\n auto result = component.processInvalid();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Resource not found\") {\n auto result = component.loadNonexistent();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Out of bounds access\") {\n REQUIRE_THROWS(component.accessOutOfBounds());\n }\n}\n```\n\n## Best Practices\n\n### DO\n\n✓ Write tests for new features before implementation (TDD)\n✓ Test both happy paths and error paths\n✓ Use descriptive test names\n✓ Keep tests focused and atomic\n✓ Test edge cases and boundary conditions\n✓ Use appropriate tags for filtering\n✓ Clean up resources in tests\n✓ Test thread safety for concurrent components\n\n### DON'T\n\n✗ Don't write tests that depend on external resources\n✗ Don't write tests that depend on execution order\n✗ Don't ignore intermittent failures\n✗ Don't test implementation details\n✗ Don't write overly complex test logic\n✗ Don't skip error path testing\n\n## Continuous Integration\n\nAll tests run automatically on:\n- Pull requests\n- Pushes to `main`\n- Multiple platforms (Linux, Windows, macOS)\n- Multiple compilers (GCC, Clang, MSVC)\n- Multiple build types (Debug, Release)\n\nSee `.github/workflows/ci.yml` and `.github/workflows/coverage.yml` for details.\n\n## References\n\n- [Catch2 Documentation](https://github.com/catchorg/Catch2/blob/devel/docs/Readme.md)\n- [CONTRIBUTING.md](../CONTRIBUTING.md) - General contribution guidelines\n- [Issue #179](https://github.com/VisageDvachevsky/StoryGraph/issues/179) - Test coverage audit\n",

--list coverage.info\n\n# Generate HTML report\ngenhtml coverage.info --output-directory coverage_html\n```\n\n#### CI Coverage\n\nCoverage reports are automatically generated in CI for:\n- Pull requests\n- Pushes to `main` branch\n\nView coverage artifacts in GitHub Actions.\n\n### Coverage Goals\n\nPer Issue #179, the coverage targets are:\n\n- **Engine Core**: ≥ 70%\n- **Editor**: ≥ 60%\n- **Overall**: Increasing coverage of critical paths\n\n### Coverage Requirements for New Code\n\nAll new code contributions must meet the following coverage requirements:\n\n#### Pull Request Coverage Standards\n\n- **New Features**: Must include tests that achieve at least 70% line coverage for the new code\n- **Bug Fixes**: Must include a regression test that reproduces the bug and verifies the fix\n- **Refactoring**: Must maintain or improve existing test coverage\n- **Critical Paths**: Security-sensitive code, data serialization, and user-facing features require 80%+ coverage\n\n#### What to Test\n\n**DO test:**\n- Public APIs and interfaces\n- Error handling and edge cases\n- Boundary conditions (null, empty, min/max values)\n- State transitions\n- Thread safety for concurrent components\n- Integration points between components\n- Critical business logic\n\n**DO NOT test:**\n- Third-party library code\n- Simple getters/setters without logic\n- Trivial forwarding functions\n- Generated code (unless it contains custom logic)\n\n#### Acceptable Exceptions\n\nSome code may be difficult or impractical to test with unit tests:\n- Platform-specific code requiring special hardware\n- GUI event handling (prefer integration tests)\n- Complex Qt widget interactions (use Qt Test framework)\n- Code that requires specific CI environment setup\n\nDocument these exceptions in code comments or PR descriptions.\n\n### Current Coverage Status\n\nRun the coverage workflow to see current metrics.\n\n## Writing Tests\n\n### Basic Test Structure\n\n```cpp\n#include <catch2/catch_test_macros.hpp>\n#include \"NovelMind/module/component.hpp\"\n\nTEST_CASE(\"Component does something\", \"[module][tag]\")\n{\n Component comp;\n\n SECTION(\"Specific behavior\") {\n comp.doSomething();\n REQUIRE(comp.getState() == ExpectedState);\n }\n\n SECTION(\"Another behavior\") {\n comp.doSomethingElse();\n REQUIRE_FALSE(comp.isFailed());\n }\n}\n```\n\n### Assertions\n\n```cpp\n// Basic assertions\nREQUIRE(expression); // Hard requirement\nREQUIRE_FALSE(expression); // Must be false\nCHECK(expression); // Soft check (continues on failure)\n\n// Comparisons\nREQUIRE(value == expected);\nREQUIRE(value != unexpected);\n\n// Floating point\n#include <catch2/catch_approx.hpp>\nREQUIRE(floatValue == Catch::Approx(expected).margin(0.01));\n\n// Exceptions\nREQUIRE_THROWS(functionThatThrows());\nREQUIRE_THROWS_AS(function(), SpecificException);\nREQUIRE_NOTHROW(safeFuncton());\n```\n\n### Test Fixtures\n\n```cpp\nclass ComponentFixture {\nprotected:\n void SetUp() {\n component = std::make_unique<Component>();\n component->initialize();\n }\n\n std::unique_ptr<Component> component;\n};\n\nTEST_CASE_METHOD(ComponentFixture, \"Test with fixture\", \"[component]\")\n{\n REQUIRE(component != nullptr);\n // Use component in tests\n}\n```\n\n## Concurrency Testing\n\n### Thread Safety Tests\n\nFor components that must be thread-safe (e.g., ResourceManager, AudioManager, PackReader):\n\n```cpp\nTEST_CASE(\"Component thread safety\", \"[component][threading]\")\n{\n Component component;\n\n SECTION(\"Concurrent operations\") {\n std::vector<std::thread> threads;\n\n // Launch multiple threads performing operations\n for (int i = 0; i < 4; ++i) {\n threads.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n component.operation();\n }\n });\n }\n\n // Wait for completion\n for (auto& t : threads) {\n t.join();\n }\n\n // Verify state\n REQUIRE(component.isValid());\n }\n}\n```\n\n### Testing with Thread Sanitizer\n\nFor comprehensive race condition detection:\n\n```bash\n# Configure with ThreadSanitizer\ncmake -B build \\\n -DCMAKE_BUILD_TYPE=Debug \\\n -DNM_BUILD_TESTS=ON \\\n -DCMAKE_CXX_FLAGS=\"-fsanitize=thread -g\"\n\n# Build and run\ncmake --build build\ncd build && ctest\n```\n\n### Common Thread Safety Patterns\n\n```cpp\n// Test reader-writer scenarios\nTEST_CASE(\"Concurrent reads and writes\", \"[threading]\")\n{\n SharedResource resource;\n std::atomic<int> readCount{0};\n std::atomic<int> writeCount{0};\n\n std::vector<std::thread> readers;\n std::vector<std::thread> writers;\n\n // Start readers\n for (int i = 0; i < 8; ++i) {\n readers.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n auto data = resource.read();\n

// Join all threads\n for (auto& t : readers) t.join();\n for (auto& t : writers) t.join();\n\n REQUIRE(readCount == 800);\n REQUIRE(writeCount == 100);\n}\n```\n\n## Performance Benchmarks\n\n### Writing Benchmarks\n\n```cpp\n#include <catch2/benchmark/catch_benchmark.hpp>\n\nTEST_CASE(\"Benchmark operation\", \"[benchmark][component]\")\n{\n Component component;\n // Setup\n\n BENCHMARK(\"Operation name\") {\n return component.operation();\n };\n}\n```\n\n### Running Benchmarks\n\n```bash\n# Run only benchmarks\n./bin/unit_tests \"[benchmark]\"\n\n# Run with samples\n./bin/unit_tests \"[benchmark]\" --benchmark-samples 100\n```\n\n### Benchmark Best Practices\n\n1. **Warmup**: Ensure code is warmed up before measuring\n2. **Consistent State**: Reset state between iterations if needed\n3. **Real-world Data**: Use realistic data sizes\n4. **Label Clearly**: Include context in benchmark names\n\n```cpp\nTEST_CASE(\"Scene rendering benchmarks\", \"[benchmark][scene]\")\n{\n SceneGraph graph;\n // Setup scene with realistic complexity\n setupRealisticScene(graph, 100); // 100 objects\n\n BENCHMARK(\"Render scene with 100 objects\") {\n graph.render(renderer);\n };\n}\n```\n\n## Integration Tests\n\n### Full Workflow Tests\n\nIntegration tests verify complete workflows:\n\n```cpp\nTEST_CASE(\"Complete dialogue scene workflow\", \"[integration][scene]\")\n{\n SceneGraph graph;\n\n // Setup scene\n graph.setSceneId(\"intro\");\n graph.showBackground(\"park.png\");\n auto* char1 = graph.showCharacter(\"alice\", \"alice\", Position::Center);\n auto* dialogue = graph.showDialogue(\"Alice\", \"Hello!\");\n\n // Simulate game loop\n for (int i = 0; i < 60; ++i) {\n graph.update(1.0 / 60.0);\n graph.render(renderer);\n }\n\n // Verify state\n REQUIRE(char1->isVisible());\n REQUIRE(dialogue->isTypewriterComplete());\n\n // Test save/load\n auto state = graph.saveState();\n SceneGraph newGraph;\n newGraph.loadState(state);\n\n REQUIRE(newGraph.getSceneId() == \"intro\");\n}\n```\n\n### Integration Test Patterns\n\n1. **Setup realistic scenarios**\n2. **Test multiple components together**\n3. **Verify end-to-end behavior**\n4. **Test save/load cycles**\n5. **Verify error recovery**\n\n## Error Path Testing\n\nAlways test error conditions:\n\n```cpp\nTEST_CASE(\"Error handling\", \"[component][error]\")\n{\n Component component;\n\n SECTION(\"Invalid input\") {\n auto result = component.processInvalid();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Resource not found\") {\n auto result = component.loadNonexistent();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Out of bounds access\") {\n REQUIRE_THROWS(component.accessOutOfBounds());\n }\n}\n```\n\n## Best Practices\n\n### DO\n\n✓ Write tests for new features before implementation (TDD)\n✓ Test both happy paths and error paths\n✓ Use descriptive test names\n✓ Keep tests focused and atomic\n✓ Test edge cases and boundary conditions\n✓ Use appropriate tags for filtering\n✓ Clean up resources in tests\n✓ Test thread safety for concurrent components\n\n### DON'T\n\n✗ Don't write tests that depend on external resources\n✗ Don't write tests that depend on execution order\n✗ Don't ignore intermittent failures\n✗ Don't test implementation details\n✗ Don't write overly complex test logic\n✗ Don't skip error path testing\n\n## Continuous Integration\n\nAll tests run automatically on:\n- Pull requests\n- Pushes to `main`\n- Multiple platforms (Linux, Windows, macOS)\n- Multiple compilers (GCC, Clang, MSVC)\n- Multiple build types (Debug, Release)\n\nSee `.github/workflows/ci.yml` and `.github/workflows/coverage.yml` for details.\n\n## References\n\n- [Catch2

Before submitting:\n\n```bash\n# Format all source files\nfind engine_core -name '*.cpp' -o -name '*.hpp' | xargs clang-format -i\n```\n\n### Pre-commit Hooks\n\nTo ensure code quality, we provide pre-commit hooks that automatically check your code before commits:\n\n```bash\n# Install pre-commit (if not already installed)\npip install pre-commit\n\n# Install the hooks\npre-commit install\n\n# Run manually on all files (optional)\npre-commit run --all-files\n```\n\nThe pre-commit hooks will:\n- Check and fix trailing whitespace\n- Ensure files end with newline\n- Validate YAML syntax\n- Run clang-format on C++ files\n- Run cppcheck for static analysis\n- Format CMake files\n\n### Naming Conventions\n\n- **Classes/Structs**: `PascalCase` (e.g., `SceneManager`)\n- **Functions/Methods**: `camelCase` (e.g., `loadScene`)\n- **Variables**: `camelCase` with `m_` prefix for members (e.g., `m_sceneGraph`)\n- **Constants**: `UPPER_SNAKE_CASE` (e.g., `MAX_SLOTS`)\n- **Namespaces**: `lowercase` (e.g., `NovelMind::scripting`)\n\n### File Organization\n\n- Headers in `engine_core/include/NovelMind/`\n- Source files in `engine_core/src/`\n- Tests in `tests/unit/` and `tests/integration/`\n\n## Submitting Changes\n\n### Pull Request Process\n\n1. Create a feature branch from `main`:\n ```bash\n git checkout -b feature/your-feature-name\n ```\n\n2. Make your changes with clear, atomic commits\n\n3. Ensure all tests pass:\n ```bash\n cd build && ctest --output-on-failure\n ```\n\n4. Push to your fork and create a Pull Request\n\n5. Fill out the PR template with:\n - Summary of changes\n - Related issue number (if applicable)\n - Test plan\n\n### Commit Messages\n\nUse clear, descriptive commit messages:\n\n```\ntype: Brief description\n\nLonger description if needed. Explain what and why,\nnot how (the code shows how).\n\nFixes #123\n```\n\nTypes: `feat`, `fix`, `docs`, `style`, `refactor`, `test`, `chore`\n\n## Bug Reports\n\nWhen reporting bugs, please include:\n\n1. **Description**: Clear description of the bug\n2. **Steps to Reproduce**: Minimal steps to reproduce the issue\n3. **Expected Behavior**: What you expected to happen\n4. **Actual Behavior**: What actually happened\n5. **Environment**: OS, compiler version, CMake version\n6. **Logs/Output**: Any relevant error messages or logs\n\n## Feature Requests\n\nFor feature requests, please describe:\n\n1. **Use Case**: Why this feature is needed\n2. **Proposed Solution**: How you envision it working\n3. **Alternatives**: Any alternatives you've considered\n\n## Testing\n\nAll code changes must include appropriate tests. See [docs/TESTING.md](docs/TESTING.md) for comprehensive testing guidelines.\n\n### Test Coverage Requirements\n\n- **New Features**: Must include tests achieving at least 70% line coverage for new code\n- **Bug Fixes**: Must include a regression test that reproduces and verifies the fix\n- **Refactoring**: Must maintain or improve existing test coverage\n- **Critical Code**: Security-sensitive code, serialization, and user-facing features require 80%+ coverage\n\n### Running Tests Locally\n\nBefore submitting a PR, ensure all tests pass:\n\n```bash\n# Configure with tests enabled\ncmake -B build -DCMAKE_BUILD_TYPE=Debug -DNM_BUILD_TESTS=ON\n\n# Build\ncmake --build build\n\n# Run all tests\ncd build && ctest --output-on-failure\n\n# Run specific test\n./bin/unit_tests \"[lexer]\"\n\n# Run with verbose output\n./bin/unit_tests -v\n\n# Run integration tests (requires editor build)\n./bin/integration_tests\n```\n\n### Test Organization\n\n- **Unit Tests**: `tests/unit/` - Test individual components in isolation\n- **Integration Tests**: `tests/integration/` - Test component interactions and workflows\n- **Test Naming**: `test_<component>.cpp` (e.g., `test_scene_graph.cpp`)\n- **Test Tags**: Use Catch2 tags for filtering (e.g., `[scene][rendering]`)\n\n### Writing Tests\n\nUse [Catch2](https://github.com/catchorg/Catch2) for all tests:\n\n```cpp\n#include <catch2/catch_test_macros.hpp>\n#include \"NovelMind/module/component.hpp\"\n\nTEST_CASE(\"Component behavior\", \"[module][component]\")\n{\n Component comp;\n\n SECTION(\"Test specific behavior\") {\n comp.doSomething();\n REQUIRE(comp.getState() == ExpectedState);\n }\n}\n```\n\n### Mocking Strategy\n\nThe project uses manual mocking (no external mocking framework):\n\n- Implement test doubles by inheriting from interfaces\n- Keep mocks simple and focused on the test scenario\n- See `tests/integration/test_scene_workflow.cpp` for mock examples\n\nFor detailed mocking patterns and best practices, see [docs/TESTING.md](docs/TESTING.md#mocking-and-test-doubles).\n\n### Checking Test Coverage Locally\n\n```bash\n# Configure with coverage flags\ncmake -B build \\\n -DCMAKE_BUILD_TYPE=Debug \\\n -DNM_BUILD_TESTS=ON \\\n -DCMAKE_CXX_FLAGS=\"--coverage\"\n\n# Build and run tests\ncmake --build build\ncd build && ctest\n\n# Generate coverage report (Linux/macOS)\nlcov --directory . --capture --output-file coverage.info\nlcov --remove coverage.info '/usr/*' '*/tests/*' '*/build/_deps/*' --output-file coverage.info\nlcov --list coverage.info\n\n# Generate HTML report\ngenhtml coverage.info --output-directory coverage_html\n```\n\n### Static Analysis\n\nRun static analysis tools locally before submitting:\n\n```bash\n# Run cppcheck\ncppcheck --enable=warning,style,performance,portability \\\n --suppress=missingIncludeSystem \\\n --suppress=unusedFunction \\\n -I engine_core/include -I editor/include \\\n engine_core/src editor/src\n\n# Run clang-tidy (requires compile_commands.json)\ncmake -B build -DCMAKE_EXPORT_COMPILE_COMMANDS=ON\nclang-tidy -p build engine_core/src/*.cpp\n```\n\n### Sanitizers\n\nTest your code with sanitizers to catch memory and threading issues:\n\n```bash\n# AddressSanitizer (detects memory errors)\ncmake -B build -DNOVELMIND_ENABLE_ASAN=ON\ncmake --build build\ncd build && ctest --output-on-failure\n\n# LeakSanitizer (detects memory leaks)\ncmake -B build -DNOVELMIND_ENABLE_LSAN=ON\ncmake --build build\ncd build && ctest --output-on-failure\n\n# ThreadSanitizer (detects data races)\ncmake -B build -DNOVELMIND_ENABLE_TSAN=ON\ncmake --build build\ncd build && ctest --output-on-failure\n\n# UndefinedBehaviorSanitizer (detects undefined behavior)\ncmake -B build -DNOVELMIND_ENABLE_UBSAN=ON\ncmake --build build\ncd build && ctest --output-on-failure\n```\n\n### Writing Tests\n\n- Use Catch2 for unit tests\n- Place unit tests in `tests/unit/`\n- Name test files `test_<component>.cpp`\n- Cover edge cases and error conditions\n\n## Questions?\n\nIf you have questions about contributing, feel free to:\n\n1. Open an issue with the \"question\" label\n2. Check existing documentation in `docs/`\n\nThank you for contributing to NovelMind!\n",

// Hard requirement\nREQUIRE_FALSE(expression); // Must be false\nCHECK(expression); // Soft check (continues on failure)\n\n// Comparisons\nREQUIRE(value == expected);\nREQUIRE(value != unexpected);\n\n// Floating point\n#include <catch2/catch_approx.hpp>\nREQUIRE(floatValue == Catch::Approx(expected).margin(0.01));\n\n// Exceptions\nREQUIRE_THROWS(functionThatThrows());\nREQUIRE_THROWS_AS(function(), SpecificException);\nREQUIRE_NOTHROW(safeFuncton());\n```\n\n### Test Fixtures\n\n```cpp\nclass ComponentFixture {\nprotected:\n void SetUp() {\n component = std::make_unique<Component>();\n component->initialize();\n }\n\n std::unique_ptr<Component> component;\n};\n\nTEST_CASE_METHOD(ComponentFixture, \"Test with fixture\", \"[component]\")\n{\n REQUIRE(component != nullptr);\n // Use component in tests\n}\n```\n\n### Mocking and Test Doubles\n\nThe project uses manual mocking (test doubles) rather than a mocking framework. This provides full control and keeps dependencies minimal.\n\n#### When to Use Mocks\n\nUse mocks/test doubles when:\n- Testing components that depend on external resources (filesystem, network, hardware)\n- Testing components that interact with slow or non-deterministic systems\n- Isolating the unit under test from its dependencies\n- Testing error conditions that are hard to trigger with real implementations\n\n#### Creating Mock Objects\n\nMocks should implement the same interface as the real object:\n\n```cpp\n// Real interface\nclass IRenderer {\npublic:\n virtual ~IRenderer() = default;\n virtual void drawSprite(const Texture& texture, const Transform2D& transform) = 0;\n virtual void drawText(const Font& font, const std::string& text, f32 x, f32 y) = 0;\n virtual i32 getWidth() const = 0;\n virtual i32 getHeight() const = 0;\n};\n\n// Mock implementation for testing\nclass MockRenderer : public IRenderer {\npublic:\n void drawSprite(const Texture& texture, const Transform2D& transform) override {\n drawSpriteCalls++;\n lastTexture = texture.getId();\n }\n\n void drawText(const Font& font, const std::string& text, f32 x, f32 y) override {\n drawTextCalls++;\n lastText = text;\n }\n\n i32 getWidth() const override { return 1920; }\n i32 getHeight() const override { return 1080; }\n\n // Test instrumentation\n int drawSpriteCalls = 0;\n int drawTextCalls = 0;\n std::string lastTexture;\n std::string lastText;\n};\n\n// Usage in tests\nTEST_CASE(\"Scene renders correctly\", \"[scene][rendering]\") {\n MockRenderer renderer;\n SceneGraph scene;\n\n scene.showBackground(\"bg.png\");\n scene.render(renderer);\n\n REQUIRE(renderer.drawSpriteCalls == 1);\n REQUIRE(renderer.lastTexture == \"bg.png\");\n}\n```\n\n#### Mock Best Practices\n\n**DO:**\n- Keep mocks simple and focused\n- Implement only the interface methods used by the test\n- Use meaningful default return values\n- Track method calls and arguments for verification\n- Reset mock state between test sections if reused\n- Name mocks clearly: `MockRenderer`, `TestRenderer`, `FakeFileSystem`\n\n**DON'T:**\n- Don't make mocks too complex with intricate logic\n- Don't reuse mocks across unrelated tests\n- Don't test the mock itself (test the real implementation separately)\n- Don't over-specify mock expectations (makes tests brittle)\n\n#### Types of Test Doubles\n\n**Dummy**: Objects passed around but never used (satisfies parameter requirements)\n```cpp\nclass DummyWindow : public IWindow {\n // Minimal implementation, methods can throw or do nothing\n};\n```\n\n**Stub**: Provides canned responses to calls\n```cpp\nclass StubResourceManager : public IResourceManager {\n Texture* loadTexture(const std::string& path) override {\n return &m_defaultTexture; // Always returns same texture\n }\nprivate:\n Texture m_defaultTexture;\n};\n```\n\n**Mock**: Records calls and allows verification\n```cpp\nclass MockAudioManager : public IAudioManager {\n void playSound(const std::string& soundId) override {\n playedSounds.push_back(soundId);\n }\n std::vector<std::string> playedSounds;\n};\n```\n\n**Fake**: Working implementation with shortcuts (e.g., in-memory database)\n```cpp\nclass FakeFileSystem : public IFileSystem {\n // Real implementation using in-memory map instead of real filesystem\n std::unordered_map<std::string, std::vector<uint8_t>> files;\n};\n```\n\n#### Mocking Patterns\n\n**Spy Pattern**: Real object with call recording\n```cpp\nclass SpyRenderer : public Renderer {\n void drawSprite(const Texture& texture, const Transform2D& transform) override {\n drawCalls.push_back({texture.getId(), transform});\n Renderer::drawSprite(texture, transform); // Call real implementation\n }\n\n struct DrawCall {\n std::string textureId;\n Transform2D transform;\n };\n std::vector<DrawCall> drawCalls;\n};\n```\n\n**Builder Pattern for Complex Mocks**: When mocks need configuration\n```cpp\nclass MockRendererBuilder {\npublic:\n MockRendererBuilder& withWidth(i32 w) { width = w; return *this; }\n MockRendererBuilder& withHeight(i32 h) { height = h; return *this; }\n MockRendererBuilder& failOnDraw() { shouldFailOnDraw = true; return *this; }\n\n MockRenderer build() {\n MockRenderer renderer;\n renderer.width = width;\n renderer.height = height;\n renderer.shouldFail = shouldFailOnDraw;\n return renderer;\n }\n\nprivate:\n i32 width = 1920;\n i32 height = 1080;\n bool shouldFailOnDraw = false;\n};\n\n// Usage\nTEST_CASE(\"Handle render failure\", \"[rendering]\") {\n auto renderer = MockRendererBuilder()\n .withWidth(800)\n .withHeight(600)\n .failOnDraw()\n .build();\n // Test error handling\n}\n```\n\n#### Examples from Codebase\n\nSee these files for real mocking examples:\n- `tests/integration/test_scene_workflow.cpp` - IntegrationMockRenderer\n- `tests/integration/test_animation_integration.cpp` - MockSceneObject\n- `tests/unit/test_scene_graph_deep.cpp` - MockWindow\n```\n\n## Concurrency Testing\n\n### Thread Safety Tests\n\nFor components that must be thread-safe (e.g., ResourceManager, AudioManager, PackReader):\n\n```cpp\nTEST_CASE(\"Component thread safety\", \"[component][threading]\")\n{\n Component component;\n\n SECTION(\"Concurrent operations\") {\n std::vector<std::thread> threads;\n\n // Launch multiple threads performing operations\n for (int i = 0; i < 4; ++i) {\n threads.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n component.operation();\n }\n });\n }\n\n // Wait for completion\n for (auto& t : threads) {\n t.join();\n }\n\n // Verify state\n REQUIRE(component.isValid());\n }\n}\n```\n\n### Testing with Thread Sanitizer\n\nFor comprehensive race condition detection:\n\n```bash\n# Configure with ThreadSanitizer\ncmake -B build \\\n -DCMAKE_BUILD_TYPE=Debug \\\n -DNM_BUILD_TESTS=ON \\\n -DCMAKE_CXX_FLAGS=\"-fsanitize=thread -g\"\n\n# Build and run\ncmake --build build\ncd build && ctest\n```\n\n### Common Thread Safety Patterns\n\n```cpp\n// Test reader-writer scenarios\nTEST_CASE(\"Concurrent reads and writes\", \"[threading]\")\n{\n SharedResource resource;\n std::atomic<int> readCount{0};\n std::atomic<int> writeCount{0};\n\n std::vector<std::thread> readers;\n std::vector<std::thread> writers;\n\n // Start readers\n for (int i = 0; i < 8; ++i) {\n readers.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n auto data = resource.read();\n readCount++;\n }\n });\n }\n\n // Start writers\n for (int i = 0; i < 2; ++i) {\n writers.emplace_back([&]() {\n for (int j = 0;

// Hard requirement\nREQUIRE_FALSE(expression); // Must be false\nCHECK(expression); // Soft check (continues on failure)\n\n// Comparisons\nREQUIRE(value == expected);\nREQUIRE(value != unexpected);\n\n// Floating point\n#include <catch2/catch_approx.hpp>\nREQUIRE(floatValue == Catch::Approx(expected).margin(0.01));\n\n// Exceptions\nREQUIRE_THROWS(functionThatThrows());\nREQUIRE_THROWS_AS(function(), SpecificException);\nREQUIRE_NOTHROW(safeFuncton());\n```\n\n### Test Fixtures\n\n```cpp\nclass ComponentFixture {\nprotected:\n void SetUp() {\n component = std::make_unique<Component>();\n component->initialize();\n }\n\n std::unique_ptr<Component> component;\n};\n\nTEST_CASE_METHOD(ComponentFixture, \"Test with fixture\", \"[component]\")\n{\n REQUIRE(component != nullptr);\n // Use component in tests\n}\n```\n\n### Mocking and Test Doubles\n\nThe project uses manual mocking (test doubles) rather than a mocking framework. This provides full control and keeps dependencies minimal.\n\n#### When to Use Mocks\n\nUse mocks/test doubles when:\n- Testing components that depend on external resources (filesystem, network, hardware)\n- Testing components that interact with slow or non-deterministic systems\n- Isolating the unit under test from its dependencies\n- Testing error conditions that are hard to trigger with real implementations\n\n#### Creating Mock Objects\n\nMocks should implement the same interface as the real object:\n\n```cpp\n// Real interface\nclass IRenderer {\npublic:\n virtual ~IRenderer() = default;\n virtual void drawSprite(const Texture& texture, const Transform2D& transform) = 0;\n virtual void drawText(const Font& font, const std::string& text, f32 x, f32 y) = 0;\n virtual i32 getWidth() const = 0;\n virtual i32 getHeight() const = 0;\n};\n\n// Mock implementation for testing\nclass MockRenderer : public IRenderer {\npublic:\n void drawSprite(const Texture& texture, const Transform2D& transform) override {\n drawSpriteCalls++;\n lastTexture = texture.getId();\n }\n\n void drawText(const Font& font, const std::string& text, f32 x, f32 y) override {\n drawTextCalls++;\n lastText = text;\n }\n\n i32 getWidth() const override { return 1920; }\n i32 getHeight() const override { return 1080; }\n\n // Test instrumentation\n int drawSpriteCalls = 0;\n int drawTextCalls = 0;\n std::string lastTexture;\n std::string lastText;\n};\n\n// Usage in tests\nTEST_CASE(\"Scene renders correctly\", \"[scene][rendering]\") {\n MockRenderer renderer;\n SceneGraph scene;\n\n scene.showBackground(\"bg.png\");\n scene.render(renderer);\n\n REQUIRE(renderer.drawSpriteCalls == 1);\n REQUIRE(renderer.lastTexture == \"bg.png\");\n}\n```\n\n#### Mock Best Practices\n\n**DO:**\n- Keep mocks simple and focused\n- Implement only the interface methods used by the test\n- Use meaningful default return values\n- Track method calls and arguments for verification\n- Reset mock state between test sections if reused\n- Name mocks clearly: `MockRenderer`, `TestRenderer`, `FakeFileSystem`\n\n**DON'T:**\n- Don't make mocks too complex with intricate logic\n- Don't reuse mocks across unrelated tests\n- Don't test the mock itself (test the real implementation separately)\n- Don't over-specify mock expectations (makes tests brittle)\n\n#### Types of Test Doubles\n\n**Dummy**: Objects passed around but never used (satisfies parameter requirements)\n```cpp\nclass DummyWindow : public IWindow {\n // Minimal implementation, methods can throw or do nothing\n};\n```\n\n**Stub**: Provides canned responses to calls\n```cpp\nclass StubResourceManager : public IResourceManager {\n Texture* loadTexture(const std::string& path) override {\n return &m_defaultTexture; // Always returns same texture\n }\nprivate:\n Texture m_defaultTexture;\n};\n```\n\n**Mock**: Records calls and allows verification\n```cpp\nclass MockAudioManager : public IAudioManager {\n void playSound(const std::string& soundId) override {\n playedSounds.push_back(soundId);\n }\n std::vector<std::string> playedSounds;\n};\n```\n\n**Fake**: Working implementation with shortcuts (e.g., in-memory database)\n```cpp\nclass FakeFileSystem : public IFileSystem {\n // Real implementation using in-memory map instead of real filesystem\n std::unordered_map<std::string, std::vector<uint8_t>> files;\n};\n```\n\n#### Mocking Patterns\n\n**Spy Pattern**: Real object with call recording\n```cpp\nclass SpyRenderer : public Renderer {\n void drawSprite(const Texture& texture, const Transform2D& transform) override {\n drawCalls.push_back({texture.getId(), transform});\n Renderer::drawSprite(texture, transform); // Call real implementation\n }\n\n struct DrawCall {\n std::string textureId;\n Transform2D transform;\n };\n std::vector<DrawCall> drawCalls;\n};\n```\n\n**Builder Pattern for Complex Mocks**: When mocks need configuration\n```cpp\nclass MockRendererBuilder {\npublic:\n MockRendererBuilder& withWidth(i32 w) { width = w; return *this; }\n MockRendererBuilder& withHeight(i32 h) { height = h; return *this; }\n MockRendererBuilder& failOnDraw() { shouldFailOnDraw = true; return *this; }\n\n MockRenderer build() {\n MockRenderer renderer;\n renderer.width = width;\n renderer.height = height;\n renderer.shouldFail = shouldFailOnDraw;\n return renderer;\n }\n\nprivate:\n i32 width = 1920;\n i32 height = 1080;\n bool shouldFailOnDraw = false;\n};\n\n// Usage\nTEST_CASE(\"Handle render failure\", \"[rendering]\") {\n auto renderer = MockRendererBuilder()\n .withWidth(800)\n .withHeight(600)\n .failOnDraw()\n .build();\n // Test error handling\n}\n```\n\n#### Examples from Codebase\n\nSee these files for real mocking examples:\n- `tests/integration/test_scene_workflow.cpp` - IntegrationMockRenderer\n- `tests/integration/test_animation_integration.cpp` - MockSceneObject\n- `tests/unit/test_scene_graph_deep.cpp` - MockWindow\n```\n\n## Concurrency Testing\n\n### Thread Safety Tests\n\nFor components that must be thread-safe (e.g., ResourceManager, AudioManager, PackReader):\n\n```cpp\nTEST_CASE(\"Component thread safety\", \"[component][threading]\")\n{\n Component component;\n\n SECTION(\"Concurrent operations\") {\n std::vector<std::thread> threads;\n\n // Launch multiple threads performing operations\n for (int i = 0; i < 4; ++i) {\n threads.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n component.operation();\n }\n });\n }\n\n // Wait for completion\n for (auto& t : threads) {\n t.join();\n }\n\n // Verify state\n REQUIRE(component.isValid());\n }\n}\n```\n\n### Testing with Thread Sanitizer\n\nFor comprehensive race condition detection:\n\n```bash\n# Configure with ThreadSanitizer\ncmake -B build \\\n -DCMAKE_BUILD_TYPE=Debug \\\n -DNM_BUILD_TESTS=ON \\\n -DCMAKE_CXX_FLAGS=\"-fsanitize=thread -g\"\n\n# Build and run\ncmake --build build\ncd build && ctest\n```\n\n### Common Thread Safety Patterns\n\n```cpp\n// Test reader-writer scenarios\nTEST_CASE(\"Concurrent reads and writes\", \"[threading]\")\n{\n SharedResource resource;\n std::atomic<int> readCount{0};\n std::atomic<int> writeCount{0};\n\n std::vector<std::thread> readers;\n std::vector<std::thread> writers;\n\n // Start readers\n for (int i = 0; i < 8; ++i) {\n readers.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n auto data = resource.read();\n readCount++;\n }\n });\n }\n\n // Start writers\n for (int i = 0; i < 2; ++i) {\n writers.emplace_back([&]() {\n for (int j = 0; j < 50; ++j) {\n resource.write(j);\n writeCount++;\n }\n });\n }\n\n // Join all threads\n for (auto& t : readers) t.join();\n for (auto& t : writers) t.join();\n\n REQUIRE(readCount == 800);\n REQUIRE(writeCount == 100);\n}\n```\n\n## Performance Benchmarks\n\n### Writing Benchmarks\n\n```cpp\n#include <catch2/benchmark/catch_benchmark.hpp>\n\nTEST_CASE(\"Benchmark operation\", \"[benchmark][component]\")\n{\n Component component;\n // Setup\n\n BENCHMARK(\"Operation name\") {\n return component.operation();\n };\n}\n```\n\n### Running Benchmarks\n\n```bash\n# Run only benchmarks\n./bin/unit_tests \"[benchmark]\"\n\n# Run with samples\n./bin/unit_tests \"[benchmark]\" --benchmark-samples 100\n```\n\n### Benchmark Best Practices\n\n1. **Warmup**: Ensure code is warmed up before measuring\n2. **Consistent State**: Reset state between iterations if needed\n3. **Real-world Data**: Use realistic data sizes\n4. **Label Clearly**: Include context in benchmark names\n\n```cpp\nTEST_CASE(\"Scene rendering benchmarks\", \"[benchmark][scene]\")\n{\n SceneGraph graph;\n // Setup scene with realistic complexity\n setupRealisticScene(graph, 100); // 100 objects\n\n BENCHMARK(\"Render scene with 100 objects\") {\n graph.render(renderer);\n };\n}\n```\n\n## Integration Tests\n\n### Full Workflow Tests\n\nIntegration tests verify complete workflows:\n\n```cpp\nTEST_CASE(\"Complete dialogue scene workflow\", \"[integration][scene]\")\n{\n SceneGraph graph;\n\n // Setup scene\n graph.setSceneId(\"intro\");\n graph.showBackground(\"park.png\");\n auto* char1 = graph.showCharacter(\"alice\", \"alice\", Position::Center);\n auto* dialogue = graph.showDialogue(\"Alice\", \"Hello!\");\n\n // Simulate game loop\n for (int i = 0;

This provides full control and keeps dependencies minimal.\n\n#### When to Use Mocks\n\nUse mocks/test doubles when:\n- Testing components that depend on external resources (filesystem, network, hardware)\n- Testing components that interact with slow or non-deterministic systems\n- Isolating the unit under test from its dependencies\n- Testing error conditions that are hard to trigger with real implementations\n\n#### Creating Mock Objects\n\nMocks should implement the same interface as the real object:\n\n```cpp\n// Real interface\nclass IRenderer {\npublic:\n virtual ~IRenderer() = default;\n virtual void drawSprite(const Texture& texture, const Transform2D& transform) = 0;\n virtual void drawText(const Font& font, const std::string& text, f32 x, f32 y) = 0;\n virtual i32 getWidth() const = 0;\n virtual i32 getHeight() const = 0;\n};\n\n// Mock implementation for testing\nclass MockRenderer : public IRenderer {\npublic:\n void drawSprite(const Texture& texture, const Transform2D& transform) override {\n drawSpriteCalls++;\n lastTexture = texture.getId();\n }\n\n void drawText(const Font& font, const std::string& text, f32 x, f32 y) override {\n drawTextCalls++;\n lastText = text;\n }\n\n i32 getWidth() const override { return 1920; }\n i32 getHeight() const override { return 1080; }\n\n // Test instrumentation\n int drawSpriteCalls = 0;\n int drawTextCalls = 0;\n std::string lastTexture;\n std::string lastText;\n};\n\n// Usage in tests\nTEST_CASE(\"Scene renders correctly\", \"[scene][rendering]\") {\n MockRenderer renderer;\n SceneGraph scene;\n\n scene.showBackground(\"bg.png\");\n scene.render(renderer);\n\n REQUIRE(renderer.drawSpriteCalls == 1);\n REQUIRE(renderer.lastTexture == \"bg.png\");\n}\n```\n\n#### Mock Best Practices\n\n**DO:**\n- Keep mocks simple and focused\n- Implement only the interface methods used by the test\n- Use meaningful default return values\n- Track method calls and arguments for verification\n- Reset mock state between test sections if reused\n- Name mocks clearly: `MockRenderer`, `TestRenderer`, `FakeFileSystem`\n\n**DON'T:**\n- Don't make mocks too complex with intricate logic\n- Don't reuse mocks across unrelated tests\n- Don't test the mock itself (test the real implementation separately)\n- Don't over-specify mock expectations (makes tests brittle)\n\n#### Types of Test Doubles\n\n**Dummy**: Objects passed around but never used (satisfies parameter requirements)\n```cpp\nclass DummyWindow : public IWindow {\n // Minimal implementation, methods can throw or do nothing\n};\n```\n\n**Stub**: Provides canned responses to calls\n```cpp\nclass StubResourceManager : public IResourceManager {\n Texture* loadTexture(const std::string& path) override {\n return &m_defaultTexture; // Always returns same texture\n }\nprivate:\n Texture m_defaultTexture;\n};\n```\n\n**Mock**: Records calls and allows verification\n```cpp\nclass MockAudioManager : public IAudioManager {\n void playSound(const std::string& soundId) override {\n playedSounds.push_back(soundId);\n }\n std::vector<std::string> playedSounds;\n};\n```\n\n**Fake**: Working implementation with shortcuts (e.g., in-memory database)\n```cpp\nclass FakeFileSystem : public IFileSystem {\n // Real implementation using in-memory map instead of real filesystem\n std::unordered_map<std::string, std::vector<uint8_t>> files;\n};\n```\n\n#### Mocking Patterns\n\n**Spy Pattern**: Real object with call recording\n```cpp\nclass SpyRenderer : public Renderer {\n void drawSprite(const Texture& texture, const Transform2D& transform) override {\n drawCalls.push_back({texture.getId(), transform});\n Renderer::drawSprite(texture, transform); // Call real implementation\n }\n\n struct DrawCall {\n std::string textureId;\n Transform2D transform;\n };\n std::vector<DrawCall> drawCalls;\n};\n```\n\n**Builder Pattern for Complex Mocks**: When mocks need configuration\n```cpp\nclass MockRendererBuilder {\npublic:\n MockRendererBuilder& withWidth(i32 w) { width = w; return *this; }\n MockRendererBuilder& withHeight(i32 h) { height = h; return *this; }\n MockRendererBuilder& failOnDraw() { shouldFailOnDraw = true; return *this; }\n\n MockRenderer build() {\n MockRenderer renderer;\n renderer.width = width;\n renderer.height = height;\n renderer.shouldFail = shouldFailOnDraw;\n return renderer;\n }\n\nprivate:\n i32 width = 1920;\n i32 height = 1080;\n bool shouldFailOnDraw = false;\n};\n\n// Usage\nTEST_CASE(\"Handle render failure\", \"[rendering]\")
[2026-01-11T18:38:40.960Z] [INFO] {\n auto renderer = MockRendererBuilder()\n .withWidth(800)\n .withHeight(600)\n .failOnDraw()\n .build();\n // Test error handling\n}\n```\n\n#### Examples from Codebase\n\nSee these files for real mocking examples:\n- `tests/integration/test_scene_workflow.cpp` - IntegrationMockRenderer\n- `tests/integration/test_animation_integration.cpp` - MockSceneObject\n- `tests/unit/test_scene_graph_deep.cpp` - MockWindow\n```\n\n## Concurrency Testing\n\n### Thread Safety Tests\n\nFor components that must be thread-safe (e.g., ResourceManager, AudioManager, PackReader):\n\n```cpp\nTEST_CASE(\"Component thread safety\", \"[component][threading]\")\n{\n Component component;\n\n SECTION(\"Concurrent operations\") {\n std::vector<std::thread> threads;\n\n // Launch multiple threads performing operations\n for (int i = 0; i < 4; ++i) {\n threads.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n component.operation();\n }\n });\n }\n\n // Wait for completion\n for (auto& t : threads) {\n t.join();\n }\n\n // Verify state\n REQUIRE(component.isValid());\n }\n}\n```\n\n### Testing with Thread Sanitizer\n\nFor comprehensive race condition detection:\n\n```bash\n# Configure with ThreadSanitizer\ncmake -B build \\\n -DCMAKE_BUILD_TYPE=Debug \\\n -DNM_BUILD_TESTS=ON \\\n -DCMAKE_CXX_FLAGS=\"-fsanitize=thread -g\"\n\n# Build and run\ncmake --build build\ncd build && ctest\n```\n\n### Common Thread Safety Patterns\n\n```cpp\n// Test reader-writer scenarios\nTEST_CASE(\"Concurrent reads and writes\", \"[threading]\")\n{\n SharedResource resource;\n std::atomic<int> readCount{0};\n std::atomic<int> writeCount{0};\n\n std::vector<std::thread> readers;\n std::vector<std::thread> writers;\n\n // Start readers\n for (int i = 0; i < 8; ++i) {\n readers.emplace_back([&]() {\n for (int j = 0; j < 100; ++j) {\n auto data = resource.read();\n readCount++;\n }\n });\n }\n\n // Start writers\n for (int i = 0; i < 2; ++i) {\n writers.emplace_back([&]() {\n for (int j = 0; j < 50; ++j) {\n resource.write(j);\n writeCount++;\n }\n });\n }\n\n // Join all threads\n for (auto& t : readers) t.join();\n for (auto& t : writers) t.join();\n\n REQUIRE(readCount == 800);\n REQUIRE(writeCount == 100);\n}\n```\n\n## Performance Benchmarks\n\n### Writing Benchmarks\n\n```cpp\n#include <catch2/benchmark/catch_benchmark.hpp>\n\nTEST_CASE(\"Benchmark operation\", \"[benchmark][component]\")\n{\n Component component;\n // Setup\n\n BENCHMARK(\"Operation name\") {\n return component.operation();\n };\n}\n```\n\n### Running Benchmarks\n\n```bash\n# Run only benchmarks\n./bin/unit_tests \"[benchmark]\"\n\n# Run with samples\n./bin/unit_tests \"[benchmark]\" --benchmark-samples 100\n```\n\n### Benchmark Best Practices\n\n1. **Warmup**: Ensure code is warmed up before measuring\n2. **Consistent State**: Reset state between iterations if needed\n3. **Real-world Data**: Use realistic data sizes\n4. **Label Clearly**: Include context in benchmark names\n\n```cpp\nTEST_CASE(\"Scene rendering benchmarks\", \"[benchmark][scene]\")\n{\n SceneGraph graph;\n // Setup scene with realistic complexity\n setupRealisticScene(graph, 100); // 100 objects\n\n BENCHMARK(\"Render scene with 100 objects\") {\n graph.render(renderer);\n };\n}\n```\n\n## Integration Tests\n\n### Full Workflow Tests\n\nIntegration tests verify complete workflows:\n\n```cpp\nTEST_CASE(\"Complete dialogue scene workflow\", \"[integration][scene]\")\n{\n SceneGraph graph;\n\n // Setup scene\n graph.setSceneId(\"intro\");\n graph.showBackground(\"park.png\");\n auto* char1 = graph.showCharacter(\"alice\", \"alice\", Position::Center);\n auto* dialogue = graph.showDialogue(\"Alice\", \"Hello!\");\n\n // Simulate game loop\n for (int i = 0; i < 60; ++i) {\n graph.update(1.0 / 60.0);\n graph.render(renderer);\n }\n\n // Verify state\n REQUIRE(char1->isVisible());\n REQUIRE(dialogue->isTypewriterComplete());\n\n // Test save/load\n auto state = graph.saveState();\n SceneGraph newGraph;\n newGraph.loadState(state);\n\n REQUIRE(newGraph.getSceneId() == \"intro\");\n}\n```\n\n### Integration Test Patterns\n\n1. **Setup realistic scenarios**\n2. **Test multiple components together**\n3. **Verify end-to-end behavior**\n4. **Test save/load cycles**\n5. **Verify error recovery**\n\n## Error Path Testing\n\nAlways test error conditions:\n\n```cpp\nTEST_CASE(\"Error handling\", \"[component][error]\")\n{\n Component component;\n\n SECTION(\"Invalid input\") {\n auto result = component.processInvalid();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Resource not found\") {\n auto result = component.loadNonexistent();\n REQUIRE(result.isError());\n }\n\n SECTION(\"Out of bounds access\") {\n REQUIRE_THROWS(component.accessOutOfBounds());\n }\n}\n```\n\n## Best Practices\n\n### DO\n\n✓ Write tests for new features before implementation (TDD)\n✓ Test both happy paths and error paths\n✓ Use descriptive test names\n✓ Keep tests focused and atomic\n✓ Test edge cases and boundary conditions\n✓ Use appropriate tags for filtering\n✓ Clean up resources in tests\n✓ Test thread safety for concurrent components\n\n### DON'T\n\n✗ Don't write tests that depend on external resources\n✗ Don't write tests that depend on execution order\n✗ Don't ignore intermittent failures\n✗ Don't test implementation details\n✗ Don't write overly complex test logic\n✗ Don't skip error path testing\n\n## Continuous Integration\n\nAll tests run automatically on:\n- Pull requests\n- Pushes to `main`\n- Multiple platforms (Linux, Windows, macOS)\n- Multiple compilers (GCC, Clang, MSVC)\n- Multiple build types (Debug, Release)\n\nSee `.github/workflows/ci.yml` and `.github/workflows/coverage.yml` for details.\n\n## References\n\n- [Catch2 Documentation](https://github.com/catchorg/Catch2/blob/devel/docs/Readme.md)\n- [CONTRIBUTING.md](../CONTRIBUTING.md) - General contribution guidelines\n- [Issue #179](https://github.com/VisageDvachevsky/StoryGraph/issues/179) - Test coverage audit\n","structuredPatch":[{"oldStart":450,"oldLines":7,"newStart":450,"newLines":7,"lines":[" # Configure with ThreadSanitizer"," cmake -B build \\"," -DCMAKE_BUILD_TYPE=Debug \\","- -DNM_BUILD_TESTS=ON \\","+ -DNOVELMIND_BUILD_TESTS=ON \\"," -DCMAKE_CXX_FLAGS=\"-fsanitize=thread -g\""," "," # Build and run"]}],"userModified":false,"replaceAll":false}}
