您可以或多或少地按照您的描述执行此操作。您可以添加一个无法编译的目标,然后添加一个调用cmake --build
以尝试构建目标的测试。剩下的就是将 test 属性设置WILL_FAIL
为 true。
因此,假设您将测试放在名为“will_fail.cpp”的文件中,其中包含:
#if defined TEST1
non-compiling code for test 1
#elif defined TEST2
non-compiling code for test 2
#endif
然后你可以在你的 CMakeLists.txt 中有如下内容:
cmake_minimum_required(VERSION 3.0)
project(Example)
include(CTest)
# Add a couple of failing-to-compile targets
add_executable(will_fail will_fail.cpp)
add_executable(will_fail_again will_fail.cpp)
# Avoid building these targets normally
set_target_properties(will_fail will_fail_again PROPERTIES
EXCLUDE_FROM_ALL TRUE
EXCLUDE_FROM_DEFAULT_BUILD TRUE)
# Provide a PP definition to target the appropriate part of
# "will_fail.cpp", or provide separate files per test.
target_compile_definitions(will_fail PRIVATE TEST1)
target_compile_definitions(will_fail_again PRIVATE TEST2)
# Add the tests. These invoke "cmake --build ..." which is a
# cross-platform way of building the given target.
add_test(NAME Test1
COMMAND ${CMAKE_COMMAND} --build . --target will_fail --config $<CONFIGURATION>
WORKING_DIRECTORY ${CMAKE_BINARY_DIR})
add_test(NAME Test2
COMMAND ${CMAKE_COMMAND} --build . --target will_fail_again --config $<CONFIGURATION>
WORKING_DIRECTORY ${CMAKE_BINARY_DIR})
# Expect these tests to fail (i.e. cmake --build should return
# a non-zero value)
set_tests_properties(Test1 Test2 PROPERTIES WILL_FAIL TRUE)
如果你有很多这些要写的话,你显然可以将所有这些包装到一个函数或宏中。
