Detailed Description

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,

 #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();
 };

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 

 static CppUnit::TestSuite *suite()
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. 

 CPPUNIT_TEST_SUITE_REGISTRATION( MyTest );
 CppUnit::Test* tp =
   CppUnit::TestFactoryRegistry::getRegistry().makeTest();

The test suite macros can even be used with templated test classes. For example:

 template<typename CharType>
 class StringTest : public CppUnit::TestFixture {
   CPPUNIT_TEST_SUITE( StringTest );
   CPPUNIT_TEST( testAppend );
   CPPUNIT_TEST_SUITE_END();
 public:  
   ...
 };

You need to add in an implementation file:

 CPPUNIT_TEST_SUITE_REGISTRATION( StringTest<char> );
 CPPUNIT_TEST_SUITE_REGISTRATION( StringTest<wchar_t> );
