/*! \brief Generate a test case from a fixture method.
* \ingroup WritingTestFixture
*
* A test caller provides access to a test case method
* on a test fixture class. Test callers are useful when
* you want to run an individual test or add it to a
* suite.
* Test Callers invoke only one Test (i.e. test method) on one
* Fixture of a TestFixture.
*
* Here is an example:
* \code
* class MathTest : public CppUnit::TestFixture {
* ...
* public:
* void setUp();
* void tearDown();
*
* void testAdd();
* void testSubtract();
* };
*
* CppUnit::Test *MathTest::suite() {
* CppUnit::TestSuite *suite = new CppUnit::TestSuite;
*
* suite->addTest( new CppUnit::TestCaller<MathTest>( "testAdd", testAdd ) );
* return suite;
* }
* \endcode
*
* You can use a TestCaller to bind any test method on a TestFixture
* class, as long as it accepts void and returns void.
*
* \see TestCase
