Copilot compares mutr, testthat, and tinytest
Comparison of mutr, testthat, and tinytest
Mutr
Purpose: A minimalistic unit-testing framework designed for simplicity and ease of integration into small projects.
Features: Provides core testing functions (TEST, TEST_SET, TEST_ERROR), simple test reporting, and minimal dependency (base R).
Advantages: Extremely lightweight and easy to use for self-contained or basic testing scenarios.
Limitations: Lacks advanced features like mocking, test parameterization, or integration with CI systems, making it unsuitable for complex projects.
Testthat
Purpose: The most popular and feature-rich testing framework for R, designed for comprehensive testing of R packages.
Features: Includes a wide range of tools for unit tests, integration tests, snapshots, mocking, and test skipping. It supports structured test organization and integrates seamlessly with devtools.
Advantages: Highly versatile, supports complex test cases, integrates with CI/CD workflows, and is widely used in the R community.
Limitations: Heavier in terms of dependencies and complexity compared to simpler frameworks.
Tinytest
Purpose: A lightweight, robust testing framework aiming to balance simplicity and feature richness.
Features: Supports test discovery, parallel execution, and self-testing. It also allows tests to be included within the package itself (e.g., in the inst directory).
Advantages: Lightweight yet powerful, with a smaller dependency footprint compared to testthat. It is designed to be compatible with CRAN submission requirements.
Limitations: While it offers a good middle ground, it may not provide all the advanced features of testthat or the extreme simplicity of mutr.
Summary
If you need a basic, no-frills testing framework, "mutr" is a good choice.
For comprehensive testing needs with advanced features, "testthat" is the best option.
If you want a lightweight yet versatile framework, "tinytest" provides a good balance.
