CMake:如何使用相关目录添加 Boost.Test 用例?
我有一个使用 CMake 和 Boost.Test 的工作项目,其目录结构如下(请原谅 ASCII 艺术):
I have a working project with CMake and Boost.Test with a directory structure like this (pardon the ASCII art):
+-proj
|---CMakeLists.txt
|---build
|---test
|----dir1
| ----foo.cpp // contains one BOOST_AUTO_TEST_SUITE and several BOOST_AUTO_TEST_CASE
| |---bar.cpp // contains one BOOST_AUTO_TEST_SUITE and several BOOST_AUTO_TEST_CASE
----dir2
----foo.cpp // contains one BOOST_AUTO_TEST_SUITE and several BOOST_AUTO_TEST_CASE
|---bar.cpp // contains one BOOST_AUTO_TEST_SUITE and several BOOST_AUTO_TEST_CASE
我目前将所有源文件编译成一个可以使用 CTest 运行的大型可执行文件.我的 CMakeLists.txt 看起来像这样:
I currently compile all source files into one big executable that I can run with CTest. My CMakeLists.txt looks like this:
file(GLOB_RECURSE test_cases FOLLOW_SYMLINKS "test/*.[h,c]pp")
add_executable(test_suite ${test_cases})
include_directories(${PROJECT_SOURCE_DIR} ${Boost_INCLUDE_DIRS})
target_link_libraries(test_suite ${Boost_LIBRARIES})
include(CTest)
add_test(test_runner test_suite)
我想将每个 .cpp 文件编译成一个单独的可执行文件,并将其单独添加为测试,以便我可以使用 CTest 正则表达式机制(尤其是 Boost.Test 似乎没有的测试排除)有选择地运行某些测试.但是,当 CMake 从 dir1/dir2 为 foo/bar 生成构建目标时,我遇到了名称冲突.
I would like to compile each .cpp file into a separate executable, and add it separately as a test so that I can use the CTest regular expression machinery (especially the test exclusion which Boost.Test doesn't seem to have) to selectively run certain tests. However, I get a name conflict when CMake is generating build targets for foo/bar from dir1/dir2.
我的问题是:如何将 test
下的整个目录树镜像到 build
下的类似树,以便不再有各种可执行文件之间的名称冲突,以便 CTest 可以运行它们?
My question is: how can I mirror the entire directory tree under test
to a similar tree under build
so that there are no more name conflicts between the various executables and so that CTest can run them all?
注意:不能在源代码树中重命名它们.我想对变量 ${test_cases}
执行 foreach()
(如 这个答案),但我无法提取相关目录和文件名,并将它们移植到文件一个文件的 build/
目录中基础.
Note: Renaming them in the source tree is not an option. I'd like to do a foreach()
over the variable ${test_cases}
(as explained in this answer), but I am having trouble to extract the relative directory and the file name, and port those to the build/
directory on a file-by-file basis.
UPDATE:最后,我拼凑了这个脚本:
UPDATE: In the end, I pieced together this script:
# get the test sources
file(GLOB_RECURSE test_sources RELATIVE ${PROJECT_SOURCE_DIR} *.cpp)
# except any CMake generated sources under build/
string(REGEX REPLACE "build/[^;]+;?" "" test_sources "${test_sources}")
# get the test headers
file(GLOB_RECURSE test_headers RELATIVE ${PROJECT_SOURCE_DIR} *.hpp)
# except any CMake generated headers under build/
string(REGEX REPLACE "build/[^;]+;?" "" test_headers "${test_headers}")
# compile against the test headers, the parent project, and the Boost libraries
include_directories(${PROJECT_SOURCE_DIR} ${ParentProject_include_dirs} ${Boost_INCLUDE_DIRS})
# calls enable_testing()
include(CTest)
foreach(t ${test_sources} )
# get the relative path in the source tree
get_filename_component(test_path ${t} PATH)
# get the source name without extension
get_filename_component(test_name ${t} NAME_WE)
# concatenate the relative path and name in an underscore separated identifier
string(REPLACE "/" "_" test_concat "${test_path}/${test_name}")
# strip the leading "test_" part from the test ID
string(REGEX REPLACE "^test_" "" test_id ${test_concat})
# depend on the current source file, all the test headers, and the parent project headers
add_executable(${test_id} ${t} ${test_headers} ${ParentProject_headers})
# link against the Boost libraries
target_link_libraries(${test_id} ${Boost_LIBRARIES})
# match the relative path in the build tree with the corresponding one in the source tree
set_target_properties(${test_id} PROPERTIES RUNTIME_OUTPUT_DIRECTORY ${test_path})
# add a test with executable in the relative path of the build tree
add_test(${test_id} ${test_path}/${test_id})
endforeach()
推荐答案
可以指定 RELATIVE
标志和文件的目录( GLOB ... )
命令.虽然在文件(GLOB)文档中没有直接提到a>,这也适用于 file( GLOB_RECURSE ... )
.请注意,我在 Windows 设置中对此进行了测试.我不知道 *nix.
It is possible to specify a RELATIVE
flag and a directory to a file( GLOB ... )
command. Although not mentioned directly in the documentation of file( GLOB ), this works for file( GLOB_RECURSE ... )
too. Note, I tested this on my windows setup. I don't known about *nix.
- 连同一些 get_filename_component 调用与 <代码>NAME_WE和/或
PATH
标志,现在可以重建名称和cpp 文件相对于 globbing 目录的相对路径. - 提取路径和名称(不带扩展名)大多类似马西米利亚诺的回答.另外,我用过他的建议使用
string( REGEX REPLACE ... )
生成唯一的测试名称;用下划线替换正斜杠. - 使用唯一的测试名称,可以生成可执行文件,然后可以使用 set_target_properties.
- Together with some get_filename_component calls with
NAME_WE
and/orPATH
flags, it is now possible to reconstruct the name and the relative path of the cpp-file with respect to the globbing dir. - Extracting a path and a name (without extension) is mostly similar
to the answer by Massimiliano. In addition, I have used his
suggestion to generate a unique testname with
string( REGEX REPLACE ... )
; replacing forward slashes by underscores. - With a unique test-name, the executable can be generated and afterwards its output directory can be modified with set_target_properties.

file( GLOB_RECURSE TEST_CPP_SOURCES RELATIVE ${CMAKE_CURRENT_SOURCE_DIR} *.cpp )
foreach( test_case ${TEST_CPP_SOURCES} )
# Get the name without extension
get_filename_component( test_name ${test_case} NAME_WE )
# Get the path to the test-case, relative to the ${CMAKE_CURRENT_SOURCE_DIR}
# thanks to the RELATIVE flag in file( GLOB_RECURSE ... )
get_filename_component( test_path ${test_case} PATH )
message( STATUS " name = " ${test_name} )
message( STATUS " path = " ${test_path} )
# I would suggests constructing a 'unique' test-name
string( REPLACE "/" "_" full_testcase "${test_name}/${test_path}" )
# Add an executable using the 'unique' test-name
message( STATUS " added " ${full_testcase} " in " ${test_path} )
add_executable( ${full_testcase} ${test_case} )
# and modify its output paths.
set_target_properties( ${full_testcase} PROPERTIES RUNTIME_OUTPUT_DIRECTORY ${test_path} )
endforeach( test_case ${TEST_CPP_SOURCES} )
