| # ----------- |
| # |
| # Find CxxTest |
| # |
| # Find the CxxTest suite and declare a helper macro for creating unit |
| # tests and integrating them with CTest. For more details on CxxTest |
| # see http://cxxtest.tigris.org |
| # |
| # INPUT Variables |
| # |
| # :: |
| # |
| # CXXTEST_USE_PYTHON [deprecated since 1.3] |
| # Only used in the case both Python & Perl |
| # are detected on the system to control |
| # which CxxTest code generator is used. |
| # Valid only for CxxTest version 3. |
| # |
| # |
| # |
| # :: |
| # |
| # NOTE: In older versions of this Find Module, |
| # this variable controlled if the Python test |
| # generator was used instead of the Perl one, |
| # regardless of which scripting language the |
| # user had installed. |
| # |
| # |
| # |
| # :: |
| # |
| # CXXTEST_TESTGEN_ARGS (since CMake 2.8.3) |
| # Specify a list of options to pass to the CxxTest code |
| # generator. If not defined, --error-printer is |
| # passed. |
| # |
| # |
| # |
| # OUTPUT Variables |
| # |
| # :: |
| # |
| # CXXTEST_FOUND |
| # True if the CxxTest framework was found |
| # CXXTEST_INCLUDE_DIRS |
| # Where to find the CxxTest include directory |
| # CXXTEST_PERL_TESTGEN_EXECUTABLE |
| # The perl-based test generator |
| # CXXTEST_PYTHON_TESTGEN_EXECUTABLE |
| # The python-based test generator |
| # CXXTEST_TESTGEN_EXECUTABLE (since CMake 2.8.3) |
| # The test generator that is actually used (chosen using user preferences |
| # and interpreters found in the system) |
| # CXXTEST_TESTGEN_INTERPRETER (since CMake 2.8.3) |
| # The full path to the Perl or Python executable on the system, on |
| # platforms where the script cannot be executed using its shebang line. |
| # |
| # |
| # |
| # MACROS for optional use by CMake users: |
| # |
| # :: |
| # |
| # CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>) |
| # Creates a CxxTest runner and adds it to the CTest testing suite |
| # Parameters: |
| # test_name The name of the test |
| # gen_source_file The generated source filename to be |
| # generated by CxxTest |
| # input_files_to_testgen The list of header files containing the |
| # CxxTest::TestSuite's to be included in |
| # this runner |
| # |
| # |
| # |
| # :: |
| # |
| # #============== |
| # Example Usage: |
| # |
| # |
| # |
| # :: |
| # |
| # find_package(CxxTest) |
| # if(CXXTEST_FOUND) |
| # include_directories(${CXXTEST_INCLUDE_DIR}) |
| # enable_testing() |
| # |
| # |
| # |
| # :: |
| # |
| # CXXTEST_ADD_TEST(unittest_foo foo_test.cc |
| # ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h) |
| # target_link_libraries(unittest_foo foo) # as needed |
| # endif() |
| # |
| # |
| # |
| # :: |
| # |
| # This will (if CxxTest is found): |
| # 1. Invoke the testgen executable to autogenerate foo_test.cc in the |
| # binary tree from "foo_test.h" in the current source directory. |
| # 2. Create an executable and test called unittest_foo. |
| # |
| # |
| # |
| # :: |
| # |
| # #============= |
| # Example foo_test.h: |
| # |
| # |
| # |
| # :: |
| # |
| # #include <cxxtest/TestSuite.h> |
| # |
| # |
| # |
| # :: |
| # |
| # class MyTestSuite : public CxxTest::TestSuite |
| # { |
| # public: |
| # void testAddition( void ) |
| # { |
| # TS_ASSERT( 1 + 1 > 1 ); |
| # TS_ASSERT_EQUALS( 1 + 1, 2 ); |
| # } |
| # }; |
| |
| # Version 1.4 (11/18/10) (CMake 2.8.4) |
| # Issue 11384: Added support to the CXX_ADD_TEST macro so header |
| # files (containing the tests themselves) show up in |
| # Visual Studio and other IDEs. |
| # |
| # Version 1.3 (8/19/10) (CMake 2.8.3) |
| # Included patch by Simone Rossetto to check if either Python or Perl |
| # are present in the system. Whichever interpreter that is detected |
| # is now used to run the test generator program. If both interpreters |
| # are detected, the CXXTEST_USE_PYTHON variable is obeyed. |
| # |
| # Also added support for CXXTEST_TESTGEN_ARGS, for manually specifying |
| # options to the CxxTest code generator. |
| # Version 1.2 (3/2/08) |
| # Included patch from Tyler Roscoe to have the perl & python binaries |
| # detected based on CXXTEST_INCLUDE_DIR |
| # Version 1.1 (2/9/08) |
| # Clarified example to illustrate need to call target_link_libraries() |
| # Changed commands to lowercase |
| # Added licensing info |
| # Version 1.0 (1/8/08) |
| # Fixed CXXTEST_INCLUDE_DIRS so it will work properly |
| # Eliminated superfluous CXXTEST_FOUND assignment |
| # Cleaned up and added more documentation |
