/** \file
 * Macros intended to ease the definition of test suites.
 *
 * The macros
 * CPPUNIT_TEST_SUITE(), CPPUNIT_TEST(), and CPPUNIT_TEST_SUITE_END()
 * are designed to facilitate easy creation of a test suite.
 * For example,
 *
 * \code
 * #include <cppunit/extensions/HelperMacros.h>
 * class MyTest : public CppUnit::TestFixture {
 *   CPPUNIT_TEST_SUITE( MyTest );
 *   CPPUNIT_TEST( testEquality );
 *   CPPUNIT_TEST( testSetName );
 *   CPPUNIT_TEST_SUITE_END();
 * public:
 *   void testEquality();
 *   void testSetName();
 * };
 * \endcode
 * 
 * The effect of these macros is to define two methods in the
 * class MyTest.  The first method is an auxiliary function
 * named registerTests that you will not need to call directly.
 * The second function
 * \code static CppUnit::TestSuite *suite()\endcode
 * returns a pointer to the suite of tests defined by the CPPUNIT_TEST()
 * macros.  
 *
 * Rather than invoking suite() directly,
 * the macro CPPUNIT_TEST_SUITE_REGISTRATION() is
 * used to create a static variable that automatically
 * registers its test suite in a global registry.
 * The registry yields a Test instance containing all the
 * registered suites.
 * \code
 * CPPUNIT_TEST_SUITE_REGISTRATION( MyTest );
 * CppUnit::Test* tp =
 *   CppUnit::TestFactoryRegistry::getRegistry().makeTest();
 * \endcode
 * 
 * The test suite macros can even be used with templated test classes.
 * For example:
 *
 * \code
 * template<typename CharType>
 * class StringTest : public CppUnit::TestFixture {
 *   CPPUNIT_TEST_SUITE( StringTest );
 *   CPPUNIT_TEST( testAppend );
 *   CPPUNIT_TEST_SUITE_END();
 * public:  
 *   ...
 * };
 * \endcode
 *
 * You need to add in an implementation file:
 *
 * \code
 * CPPUNIT_TEST_SUITE_REGISTRATION( StringTest<char> );
 * CPPUNIT_TEST_SUITE_REGISTRATION( StringTest<wchar_t> );
 * \endcode
 */


/*! \brief Begin test suite
 *
 * This macro starts the declaration of a new test suite.
 * Use CPPUNIT_TEST_SUB_SUITE() instead, if you wish to include the
 * test suite of the parent class.

 *                         be derived from TestFixture.
