CTest 未检测到测试

Question

我有一个具有结构的项目

├── CMakeLists.txt
├── mzl.c
├── mzl.h
└── tests
    ├── CMakeLists.txt
    ├── mzl-communication-test.c
    ├── mzl-setup-test.c
    ├── mzl-test-errors.c
    └── mzl-test-errors.h

顶层目录CMakeLists.txt文件所在的位置

project(mzl)
cmake_minimum_required(VERSION 2.8)

add_subdirectory(tests)

# Enable testing for the project
enable_testing()

# Find zmq
find_library(ZMQ_LIB zmq REQUIRED)
message(STATUS "ZMQ Library: ${ZMQ_LIB}")

# Find threading library
set(CMAKE_THREAD_PREFER_PTHREAD ON)
find_package(Threads REQUIRED)
message(STATUS "Threading Library: ${CMAKE_THREAD_LIBS_INIT}")



# Set include directories for headers
set     (
    MZL_INCLUDE_DIRS
    ${CMAKE_SOURCE_DIR}
    CACHE STRING "MZL Include Directories"
    )
include_directories(${MZL_INCLUDE_DIRS})

# Set source files
set     (
    MZL_SRC_FILES
    mzl.c
    )

# Add library
add_library(${PROJECT_NAME} STATIC ${MZL_SRC_FILES})

# Link to zmq
target_link_libraries(${PROJECT_NAME} ${ZMQ_LIB} ${CMAKE_THREAD_LIBS_INIT})

并且 tests/CMakeLists.txt 是

# Use MZL Source Directories (mzl headers are in top directory)
include_directories(${CMAKE_SOURCE_DIR})

# Variable from here is empty
message(STATUS "MZL Include Directories: ${MZL_INCLUDE_DIRS}")

# Files common to all tests
set ( TEST_COMMON_SOURCES
    mzl-test-errors.c
    )

# Library setup/shutdown testing
set(SETUP_TEST_NAME mzl-setup-test)
add_executable(${SETUP_TEST_NAME} ${TEST_COMMON_SOURCES} ${SETUP_TEST_NAME}.c)
target_link_libraries(${SETUP_TEST_NAME} ${PROJECT_NAME} ${ZMQ_LIB})
add_test(${SETUP_TEST_NAME} ${SETUP_TEST_NAME})

# Communcations test
set(COMMUNICATION_TEST_NAME mzl-communication-test)
add_executable(${COMMUNICATION_TEST_NAME} ${TEST_COMMON_SOURCES}
    ${COMMUNICATION_TEST_NAME}.c)
target_link_libraries(${COMMUNICATION_TEST_NAME} ${PROJECT_NAME}
        ${CMAKE_THREAD_LIBS_INIT} ${ZMQ_LIB})
add_test(${COMMUNICATION_TEST_NAME}  ${COMMUNICATION_TEST_NAME})

在我添加第二个测试之前一切正常mzl-communication-test。添加它和 # Communications test 之后 tests/CMakeLists.txt 中的行之后，运行ning ctest 没有做任何额外的事情——它仍然只是运行第一个测试。

删除构建目录并再次运行ning cmake 后，初始 CMake 运行没有错误，但是运行ning make 运行s CMake 再次，导致 CMake 出错：

CMake Error: Parse error in cache file build/CMakeCache.txt. Offending entry: include

后跟 Make 错误：

Makefile:203: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1

运行 make 再次导致构建所有内容，包括测试；但是，运行宁 ctest 结果

Test project build
No tests were found!!!

问题似乎出在我用 CMake 做的事情上，但我无法从这里弄清楚该怎么做，因为我看不到我所做的事情与最初工作时有什么不同。甚至我对 git 的最后一次提交，在我提交它时是有效的，现在也不再有效了。

Answer 1

您需要先将 enable_testing() 调用移至 add_subdirectory(tests)

# Enable testing for the project
enable_testing()

add_subdirectory(tests)

CTest 未检测到测试

CTest not detecting tests

makefile

cmake

ctest
