我想默认禁用一组测试,但能够在明确定位时运行它们。

例如。假设我有一个项目,其中包含许多通过 add_test(NAME SomeNameHere COMMAND SomeCommandHere) 添加的快速运行的单元测试。命令。并进一步假设还有一堆长时间运行的集成测试应该从默认 ctest 中排除。运行,但是当明确定位时,应该可以使用单个命令运行所有集成测试。

作为一个具体的例子:

  • TestThatShouldAlwaysRun - 我希望在用户运行时运行 $ ctest
  • FooIntegrationTest - 我希望只有当用户运行时才运行 $ ctest --some-option-here integration
  • BarIntegrationTest - 我希望只有当用户运行时才运行 $ ctest --some-option-here integration

  • 这是我实现这一目标的尝试。

    cmake_minimum_required (VERSION 3.1)
    project (HOW_TO_RUN_DISABLED_TESTS NONE)
    enable_testing()

    # Add a fast running test
    # This test should be run when a user runs: 'ctest'
    add_test(NAME TestThatShouldAlwaysRun COMMAND echo 'I am always enabled')

    # Add a long-running integration test
    # This test should be run when a user runs: 'ctest --label-regex my_integration_tests'
    add_test(NAME FooIntegrationTest COMMAND echo 'Foo integration test')
    set_tests_properties(FooIntegrationTest PROPERTIES DISABLED True)
    set_tests_properties(FooIntegrationTest PROPERTIES LABELS my_integration_tests)

    # Add another long-running integration test
    # This test should be run when a user runs: 'ctest --label-regex my_integration_tests'
    add_test(NAME BarIntegrationTest COMMAND echo 'Bar integration test')
    set_tests_properties(BarIntegrationTest PROPERTIES DISABLED True)
    set_tests_properties(BarIntegrationTest PROPERTIES LABELS my_integration_tests)

    现在,让我们通过

    $ mkdir build
    $ cd build/
    $ cmake ..
    $ ctest -V

    正如我们在输出中看到的(发布在下面) ctest确实排除了集成测试(太棒了!)。
    1: Test command: /bin/echo "'I" "am" "always" "enabled'"
    1: Test timeout computed to be: 10000000
    1: 'I am always enabled'
    1/3 Test #1: TestThatShouldAlwaysRun .......... Passed 0.00 sec
    test 2
    Start 2: FooIntegrationTest
    2/3 Test #2: FooIntegrationTest ...............***Not Run (Disabled) 0.00 sec
    test 3
    Start 3: BarIntegrationTest
    3/3 Test #3: BarIntegrationTest ...............***Not Run (Disabled) 0.00 sec

    100% tests passed, 0 tests failed out of 1

    Label Time Summary:
    my_integration_tests = 0.00 sec*proc (2 tests)

    Total Test time (real) = 0.05 sec

    The following tests did not run:
    2 - FooIntegrationTest (Disabled)
    3 - BarIntegrationTest (Disabled)

    但是,我现在不知道如何通过 ctest , 运行标有 my_integration_tests 的测试.
    ctest --label-regex my_integration_tests
    Test project /path/to/code/example_repo/build
    Start 2: FooIntegrationTest
    1/2 Test #2: FooIntegrationTest ...............***Not Run (Disabled) 0.00 sec
    Start 3: BarIntegrationTest
    2/2 Test #3: BarIntegrationTest ...............***Not Run (Disabled) 0.00 sec
    No tests were found!!!

    有没有办法在明确定位时运行禁用的测试?

    我已经探索了其他方式,比如
  • 不禁用集成测试。然后,当用户想要运行快速运行的测试时,他们需要指定 ctest --label-exclude my_integration_tests .这不是很好。这让每个人都负担不起要记住这一点。我希望使用最多的选项(仅运行快速运行的测试)可以通过 ctest 运行。 .
  • 不禁用集成测试,但提供参数 CONFIGURATIONS my_integration_testsadd_test称呼。但我认为这样我在语义上误用了 CONFIGURATIONS .此外,这不允许我仅在有针对性的情况下运行集成测试。
  • 通过 add_custom_target 添加集成测试.同样在这里,我认为我在滥用 API。 add_custom_target用于自定义目标,而不是作为运行测试的一种方式,对吗?
  • 最佳答案

    我相信更简单的方法是通过 cmake 配置选项。

    # cat CMakeLists.txt 
    cmake_minimum_required (VERSION 3.1)
    project (HOW_TO_RUN_DISABLED_TESTS NONE)
    enable_testing()
    add_test(NAME TestThatShouldAlwaysRun COMMAND echo 'I am always enabled')
    if(BUILD_INTEGRATION_TESTING)
    add_test(NAME FooIntegrationTest COMMAND echo 'Foo integration test')
    add_test(NAME BarIntegrationTest COMMAND echo 'Bar integration test')
    endif()

    这很简单,也更灵活,即。允许为这些测试添加要构建的测试相关目标(和设置(和要使用的 ctest 固定装置))。 (我通常在项目中看到名为 SOMETHING_BUILD_TESTING 的变量,所以它类似于 BUILD_TESTING cmake 变量。)

    我的另一个想法是使用环境变量并将测试包装在脚本中 SKIP_RETURN_CODE (或者甚至没有 SKIP_RETURN_CODE 并且如果不应该运行集成测试就返回成功):
    add_test(NAME FooIntegrationTest 
    COMMAND sh -c "if [ \"\${RUN_INTEGRATION:-}\" ]; then echo 'Foo integration test'; else exit 127; fi"
    VERBATIM)
    set_tests_properties(FooIntegrationTest PROPERTIES
    SKIP_RETURN_CODE 127)

    然后:
    $ ctest -V
    ....
    2: Test command: /usr/bin/sh "-c" "if [ "${RUN_INTEGRATION:-}" ]; then echo 'Foo integration test'; else exit 127; fi" "VERBATIM"
    2: Test timeout computed to be: 10000000
    2/3 Test #2: FooIntegrationTest ...............***Skipped 0.01 sec
    ....
    The following tests did not run:
    2 - FooIntegrationTest (Skipped)

    但:
    $ RUN_INTEGRATION=TRUE ctest -V
    ...
    2: Test command: /usr/bin/sh "-c" "if [ "${RUN_INTEGRATION:-}" ]; then echo 'Foo integration test'; else exit 127; fi" "VERBATIM"
    2: Test timeout computed to be: 10000000
    2: Foo integration test
    2/3 Test #2: FooIntegrationTest ............... Passed 0.01 sec
    ...
