How do I configure my CMake project to run all unit tests?

问题

I have a C++ project using cmake as the build tool. My directory structure looks like the following.

.
├── cmake-build-debug
├── include
├── src
└── tests

When I am inside cmake-build-debug, I run cmake .. followed by make clean && make && make test. What I noticed is that only the first unit test is run. How do I configure my project so that when I run make test, all unit tests are run? At the root, my CMakeLists.txt looks like the following.

cmake_minimum_required(VERSION 3.10)
project(my_lib)

set(CMAKE_CXX_STANDARD 17)

add_subdirectory(src)
add_subdirectory(tests)

enable_testing()

My tests/CmakeLists.txt looks like the following (configuration taken from this website).

find_package (Boost COMPONENTS system filesystem unit_test_framework REQUIRED)
add_definitions (-DBOOST_TEST_DYN_LINK)

include_directories (../include ${Boost_INCLUDE_DIRS})

file(GLOB TEST_SRCS RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} *.cpp)

foreach(testSrc ${TEST_SRCS})
    get_filename_component(testName ${testSrc} NAME_WE)
    add_executable(${testName} ${testSrc})

    target_link_libraries(${testName} ${Boost_LIBRARIES} my_lib)

    set_target_properties(${testName} PROPERTIES
            RUNTIME_OUTPUT_DIRECTORY  ${CMAKE_CURRENT_SOURCE_DIR}/testBin)

    add_test(NAME ${testName}
            WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/testBin
            COMMAND ${CMAKE_CURRENT_SOURCE_DIR}/testBin/${testName}
            )
endforeach(testSrc)

The test target of cmake-build-debug/Makefile that is generated looks like the following.

# Special rule for the target test
test:
    @$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --cyan "Running tests..."
    /usr/bin/ctest --force-new-ctest-process $(ARGS)
.PHONY : test

# Special rule for the target test
test/fast: test

.PHONY : test/fast

The generated cmake-build-debug/CTestTestfile.cmake looks like the following.

subdirs("src")
subdirs("tests")

The generated cmake-build-debug/src/CTestTestfile.cmake is empty, but the cmake-build-debug/tests/CTestTestfile.cmake has the following content. There are more test_XYZ.cpp classes under the tests directory, but they are not being added here.

add_test(test_Dummy "/path/to/git/my_lib/tests/testBin/test_Dummy")
set_tests_properties(test_Dummy PROPERTIES  WORKING_DIRECTORY "/path/to/git/my_lib/tests/testBin")

Any ideas on what I am doing wrong?

回答1:

enable_testing() enables add_test() after it. So just make sure you call enable_testing() before any add_test() you want to enable.
