  • 4. Составить отчет и отправить ссылку личным сообщением в Slack

Tutorial

Настройка окружения

$ export GITHUB_USERNAME=<имя_пользователя> 
$ alias gsed=sed # for *-nix system #Синоним команды gsed

Заходим в свой workspace и активируем скрипты

$ cd ${GITHUB_USERNAME}/workspace
$ pushd .
~/nothingholy/workspace ~/nothingholy/workspace
$ source scripts/activate

Получаем файлы из предыдущей лабораторной работы

$ git clone https://github.com/${GITHUB_USERNAME}/lab04 projects/lab05

$ cd projects/lab05
$ git remote remove origin
$ git remote add origin https://github.com/${GITHUB_USERNAME}/lab05

Добавление подмодуля тестирования

$ mkdir third-party #Создаем папку
$ git submodule add https://github.com/google/googletest third-party/gtest #Скачиваем удаленный репозиторый в указанную папку

Редактирование CmakeLists.txt

$ gsed -i '/option(BUILD_EXAMPLES "Build examples" OFF)/a\ #Вставка строки 
option(BUILD_TESTS "Build tests" OFF)
' CMakeLists.txt
$ cat >> CMakeLists.txt <<EOF

if(BUILD_TESTS)
  enable_testing()
  add_subdirectory(third-party/gtest)
  file(GLOB \${PROJECT_NAME}_TEST_SOURCES tests/*.cpp)
  add_executable(check \${\${PROJECT_NAME}_TEST_SOURCES})
  target_link_libraries(check \${PROJECT_NAME} gtest_main)
  add_test(NAME check COMMAND check) #добавление теста с названием check и необходимой командой для его запуска
endif()
EOF

Создаем код

$ mkdir tests
$ cat > tests/test1.cpp <<EOF
#include <print.hpp>

#include <gtest/gtest.h>

TEST(Print, InFileStream)
{
  std::string filepath = "file.txt";
  std::string text = "hello";
  std::ofstream out{filepath};

  print(text, out);
  out.close();

  std::string result;
  std::ifstream in{filepath};
  in >> result;

  EXPECT_EQ(result, text);
}
EOF

Обновление Travis CI

$ gsed -i 's/lab04/lab05/g' README.md
$ gsed -i 's/\(DCMAKE_INSTALL_PREFIX=_install\)/\1 -DBUILD_TESTS=ON/' .travis.yml
$ gsed -i '/cmake --build _build --target install/a\
- cmake --build _build --target test -- ARGS=--verbose
' .travis.yml

Проверка конфига

$ travis lint

Отправка изменений

$ git add .travis.yml
$ git add tests
$ git add -p
$ git commit -m"added tests"
$ git push origin master

Активация репозитория в Travis

Homework

Задание

  1. Создайте CMakeList.txt для библиотеки banking.
  2. Создайте модульные тесты на классы Transaction и Account.
    • Используйте mock-объекты.
    • Покрытие кода должно составлять 100%.
  3. Настройте сборочную процедуру на TravisCI.
  4. Настройте Coveralls.io.
