/*! \brief Registry for TestFactory.
 * \ingroup CreatingTestSuite
 *
 * Notes that the registry assumes lifetime control for any registered test.
 *
 * To register tests, use the macros:
 * - CPPUNIT_TEST_SUITE_REGISTRATION(): to add tests in the unnamed registry.
 * - CPPUNIT_TEST_SUITE_NAMED_REGISTRATION(): to add tests in a named registry.
 *
 * Example 1: retreiving a suite that contains all the test registered with
 * CPPUNIT_TEST_SUITE_REGISTRATION().
 * \code
 * CppUnit::TestFactoryRegistry &registry = CppUnit::TestFactoryRegistry::getRegistry();
 * CppUnit::TestSuite *suite = registry.makeTest();
 * \endcode
 *
 * Example 2: retreiving a suite that contains all the test registered with
 * \link CPPUNIT_TEST_SUITE_NAMED_REGISTRATION() CPPUNIT_TEST_SUITE_NAMED_REGISTRATION( ..., "Math" )\endlink.
 * \code
 * CppUnit::TestFactoryRegistry &mathRegistry = CppUnit::TestFactoryRegistry::getRegistry( "Math" );
 * CppUnit::TestSuite *mathSuite = mathRegistry.makeTest();
 * \endcode
 *
 * Example 3: creating a test suite hierarchy composed of unnamed registration and
 * named registration:
 * - All Tests
 *   - tests registered with CPPUNIT_TEST_SUITE_NAMED_REGISTRATION( ..., "Graph" )
 *   - tests registered with CPPUNIT_TEST_SUITE_NAMED_REGISTRATION( ..., "Math" )
 *   - tests registered with CPPUNIT_TEST_SUITE_REGISTRATION
 *
 * \code
 * CppUnit::TestSuite *rootSuite = new CppUnit::TestSuite( "All tests" );
 * rootSuite->addTest( CppUnit::TestFactoryRegistry::getRegistry( "Graph" ).makeTest() );
 * rootSuite->addTest( CppUnit::TestFactoryRegistry::getRegistry( "Math" ).makeTest() );
 * CppUnit::TestFactoryRegistry::getRegistry().addTestToSuite( rootSuite );
 * \endcode
 *
 * The same result can be obtained with:
 * \code
 * CppUnit::TestFactoryRegistry &registry = CppUnit::TestFactoryRegistry::getRegistry();
 * registry.registerFactory( CppUnit::TestFactoryRegistry::getRegistry( "Graph" ) );
 * registry.registerFactory( CppUnit::TestFactoryRegistry::getRegistry( "Math" ) );
 * CppUnit::TestSuite *suite = registry.makeTest();
 * \endcode
 *
 * Since a TestFactoryRegistry is a TestFactory, the named registries can be
 * registered in the unnamed registry, creating the hierarchy links.
 *
 * \see TestSuiteFactory, AutoRegisterSuite
 * \see CPPUNIT_TEST_SUITE_REGISTRATION, CPPUNIT_TEST_SUITE_NAMED_REGISTRATION
