This appendix contains an example of a unit test header file listing and a unit test source file listing as well as a unit test container source file listing.

This test environment also contains a reference to a memory usage checker which can safely be ignored. It is also contained in the &app; environment and is a great help if looking for memory leaks. Also notice the usage of the C++ preprocessor directive #ifdef HAVE_LIBCPPUNIT to avoid compile errors when CPPUNIT is not installed. Another specialty that is not required by CPPUNIT is the specific TestProgressListener. It is used here to print the name of the fixture that is currently running. Since this method is called upon start of each test case, some logic is necessary to print the name only once. /*************************************************************************** autotest.cpp ------------------- copyright : (C) 2002 by Thomas Baumgart email : ipwizard@users.sourceforge.net ***************************************************************************/ /*************************************************************************** * * * This program is free software; you can redistribute it and/or modify * * it under the terms of the GNU General Public License as published by * * the Free Software Foundation; either version 2 of the License, or * * (at your option) any later version. * * * ***************************************************************************/ #include "config.h" #include <iostream> #ifdef HAVE_LIBCPPUNIT #include "cppunit/TextTestRunner.h" #include "cppunit/TextTestResult.h" #include "cppunit/TestSuite.h" #include "cppunit/extensions/HelperMacros.h" #include "mymoneyexceptiontest.h" #include "cppunit/TextTestProgressListener.h" class MyProgressListener : public CppUnit::TextTestProgressListener { void startTest(CppUnit::Test *test) { QString name = test->getName().c_str(); name = name.mid(2); // cut off first 2 chars name = name.left(name.find('.')); if(m_name != name) { if(m_name != "") cout << endl; cout << "Running: " << name << endl; m_name = name; } } private: QString m_name; }; #endif int main(int argc, char** argv) { #ifdef HAVE_LIBCPPUNIT #ifdef _CHECK_MEMORY _CheckMemory_Init(0); #endif CPPUNIT_TEST_SUITE_REGISTRATION(MyMoneyExceptionTest); CppUnit::TestFactoryRegistry &registry = CppUnit::TestFactoryRegistry::getRegistry(); CppUnit::Test *suite = registry.makeTest(); CppUnit::TextTestRunner* runner = new CppUnit::TextTestRunner(); runner->addTest(suite); MyProgressListener progress; runner->eventManager().addListener(&progress); runner->run(); delete runner; #ifdef _CHECK_MEMORY chkmem.CheckMemoryLeak( true ); _CheckMemory_End(); #endif // _CHECK_MEMORY #else std::cout << "libcppunit not installed. no automatic tests available." << std::endl; #endif // HAVE_LIBCPPUNIT return 0; }
