使用 cmake 构建我的项目后如何运行 ctest [英] How to run ctest after building my project with cmake

问题描述

我希望每次成功构建我的项目时都启动我的测试.如果某些测试被破坏，我希望我的构建也被破坏.默认情况下，我需要通过运行 ctest 命令手动运行测试.CTest 实际上可以构建项目，但我使用调用 make 的 IDE 来构建源代码.而且 make 不运行测试.

I want my tests to be launched each time my project is successfully built. And if some tests are broken I want my build to be broken too. By default I need to run tests manually by running ctest command. CTest can actually build project but I use IDE that invokes make to build sources. And make doesn't run tests.

我将此命令添加到我的根 CMakeLists.txt 文件中，但它不起作用.

I add this command to my root CMakeLists.txt file but it doesn't work.

add_custom_command(OUTPUT tests.txt 
                   POST_BUILD
                   COMMAND ctest --output-on-failure)

CMake 不返回任何错误，一切正常，但我的自定义命令不调用.在 CMake 中每次成功构建后，如何运行某些内容?

CMake doesn't return any errors and everything builds fine but my custom command doesn't invokes. How can I run something after each successful build in CMake?

更新:

我的最终解决方案是创建这个宏:

My final solution is creating this macro:

macro(add_unit_test target target_test)
    set(UNIT_TEST_TARGETS ${UNIT_TEST_TARGETS} ${target_test} PARENT_SCOPE)
    add_test(target ${CMAKE_CURRENT_BINARY_DIR}/${target_test})
endmacro(add_unit_test)

它调用 add_test 并记住列表中的测试目标.此宏添加的项目中的每个测试.在根 CMakeLists.txt 我有这个代码:

It calls add_test and remembers test target in a list. Every test in a project added by this macro. In the root CMakeLists.txt I have this code:

add_custom_target( all_tests ALL
                   DEPENDS ${UNIT_TEST_TARGETS}
)
add_custom_command(TARGET all_tests
                   COMMENT "Run tests"
                   POST_BUILD COMMAND ctest ARGS --output-on-failure
                   WORKING_DIRECTORY ${CMAKE_BINARY_DIR}
)

它创建依赖于项目中所有单元测试的自定义目标.自定义命令在 all_tests 目标构建后运行.

It creates custom target that depends on all unit tests in a project. Custom command is runs after all_tests target was built.

推荐答案

这种形式的 add_custom_command 仅当另一个 CMake 目标依赖于tests.txt"时才会执行.我假设没有其他目标将tests.txt"作为输入文件，因此自定义命令永远不会运行.

This form of add_custom_command will only execute if another CMake target has a dependency on "tests.txt". I assume that no other target has "tests.txt" as an input file, hence the custom command never runs.

我认为您可以使用 add_custom_command 的第二种形式来实现您的目标；类似:

I think you could use the second form of add_custom_command to achieve your goal; something like:

add_custom_command(TARGET MainTest
                   POST_BUILD
                   COMMAND ctest -C $<CONFIGURATION> --output-on-failure)
