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

问题描述

我想要每次我的项目成功建立时启动我的测试。如果一些测试被打破，我想我的构建也被打破。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I​​DE构建源。 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， 't work。

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，一切构建正常，但我的自定义命令调用。

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这个函数：

My final solution is this function:

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 ，并在列表中记住测试目标。通过此功能添加的项目中的每个测试。在根CMakeLists.txt中，我有以下代码：

it calls add_test and remembers test target in a list. Every test in a project added by this function. 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。

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

此表单已生成 all_tests add_custom_command 只有在另一个CMake目标对tests.txt有依赖性时才会执行。我假设没有其他目标有tests.txt作为输入文件，因此自定义命令从不运行。

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.

我想你可以使用第二种形式 add_custom_command 实现您的目标;例如：

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)
