| == About ==
| | {{CMake/Template/Moved}} |
|
| |
|
| This macro simplifies the inclusion of tests written using the [http://cxxtest.sourceforge.net/ CxxTest testing framework]. | | This page has moved [https://gitlab.kitware.com/cmake/community/wikis/contrib/macros/AddCxxTest here]. |
| | |
| Python is required to generate the test source files on the developer machine.
| |
| However, since the generated source files will be placed on the source directory
| |
| where the macro is called, there is no need for the end user to have Python
| |
| in order to build and run the tests.
| |
| | |
| == Definition ==
| |
| | |
| Some preamble code:
| |
| <pre>
| |
| # Make sure testing is enabled
| |
| ENABLE_TESTING()
| |
| | |
| # Use Python interpreter
| |
| FIND_PACKAGE(PythonInterp)
| |
| </pre>
| |
| | |
| You need to specify the path to the cxxtestgen.py script. Modify accordingly:
| |
| <pre>
| |
| # Path to the cxxtestgen.py script
| |
| SET(CXXTESTGEN ${CMAKE_SOURCE_DIR}/thirdparty/cxxtest/cxxtestgen.py)
| |
| </pre>
| |
| | |
| The actual macro definition:
| |
| <pre>
| |
| MACRO(ADD_CXXTEST NAME)
| |
| IF(PYTHONINTERP_FOUND)
| |
| ADD_CUSTOM_COMMAND(
| |
| OUTPUT ${CMAKE_CURRENT_SOURCE_DIR}/${NAME}.cpp
| |
| COMMAND
| |
| ${PYTHON_EXECUTABLE} ${CXXTESTGEN}
| |
| --runner=ErrorPrinter
| |
| -o ${NAME}.cpp ${ARGN}
| |
| DEPENDS ${ARGN}
| |
| WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
| |
| )
| |
| ENDIF(PYTHONINTERP_FOUND)
| |
| | |
| ADD_EXECUTABLE(${NAME} ${CMAKE_CURRENT_SOURCE_DIR}/${NAME}.cpp ${ARGN})
| |
| | |
| ADD_TEST(${NAME} ${NAME})
| |
| ENDMACRO(ADD_CXXTEST)
| |
| | |
| </pre>
| |
| | |
| | |
| == Separate compilation ==
| |
| | |
| The above macro generates a single source file for all input test headers. If by some reason you prefer separate compilation of each part, you may use the variation:
| |
| | |
| <pre>
| |
| MACRO(ADD_CXXTEST_SEP NAME)
| |
| IF(PYTHONINTERP_FOUND)
| |
| # generate the parts
| |
| FOREACH(_PART ${ARGN})
| |
| GET_FILENAME_COMPONENT(_NAME ${_PART} NAME)
| |
| GET_FILENAME_COMPONENT(_NAME_WE ${_PART} NAME_WE)
| |
| ADD_CUSTOM_COMMAND(
| |
| OUTPUT ${_NAME_WE}.cpp
| |
| COMMAND
| |
| ${PYTHON_EXECUTABLE} ${CXXTESTGEN}
| |
| --part
| |
| -o ${_NAME_WE}.cpp
| |
| ${_NAME}
| |
| DEPENDS ${_PART}
| |
| WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
| |
| )
| |
| ENDFOREACH(_PART)
| |
| | |
| # generate the runner
| |
| ADD_CUSTOM_COMMAND(
| |
| OUTPUT ${CMAKE_CURRENT_SOURCE_DIR}/${NAME}_runner.cpp
| |
| COMMAND
| |
| ${PYTHON_EXECUTABLE} ${CXXTESTGEN}
| |
| --runner=ErrorPrinter --root
| |
| -o ${NAME}_runner.cpp
| |
| WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
| |
| )
| |
| ENDIF(PYTHONINTERP_FOUND)
| |
| | |
| # enumerate all generated files
| |
| SET(PARTS ${CMAKE_CURRENT_SOURCE_DIR}/${NAME}_runner.cpp)
| |
| FOREACH(_PART ${ARGN})
| |
| GET_FILENAME_COMPONENT(_PART_WE ${_PART} NAME_WE)
| |
| SET(PARTS ${PARTS} ${_PART_WE}.cpp)
| |
| ENDFOREACH(_PART)
| |
| | |
| ADD_EXECUTABLE(${NAME} ${PARTS})
| |
| | |
| ADD_TEST(${NAME} ${NAME})
| |
| ENDMACRO(ADD_CXXTEST_SEP)
| |
| </pre>
