About
This macro simplifies the inclusion of tests written using the CxxTest testing framework.
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:
# Make sure testing is enabled
ENABLE_TESTING()
# Use Python interpreter
FIND_PACKAGE(PythonInterp)You need to specify the path to the cxxtestgen.py script. Modify accordingly:
# Path to the cxxtestgen.py script
SET(CXXTESTGEN ${CMAKE_SOURCE_DIR}/thirdparty/cxxtest/cxxtestgen.py)The actual macro definition:
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)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:
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)
