# - 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
|
|
#
|
|
# 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 intepreter 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
