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)命令添加的快速运行的单元测试。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运行中排除,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 - 我希望它在用户运行时运行 $ ctestFooIntegrationTest - 我希望它只在用户运行时运行$ ctest --some-option-here integrationBarIntegrationTest - 我希望它只在用户运行时运行$ ctest --some-option-here integration这是我实现这一目标的尝试。

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!)。

但是,我不知道我现在如何通过ctest运行标有my_integration_tests.
ctest --label-regex my_integration_tests
Test project /path/to/code/example_repo/build
Start 2: FooIntegrationTest

Start 3: BarIntegrationTest

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
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.CONFIGURATIONS my_integration_tests的add_test调用。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。add_custom_target. 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?我相信更简单的方法是通过 cmake 配置选项。
# cat CMakeLists.txt

这很简单,也更灵活,即。允许为这些测试添加要构建(和设置(以及要使用的 ctest 固定装置))的测试相关目标。(我通常在项目中看到这样命名的变量,SOMETHING_BUILD_TESTING因此它类似于BUILD_TESTINGcmake 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(或者甚至不使用SKIP_RETURN_CODE,如果不应运行集成测试则返回成功):
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
