/* 

 * A test caller provides access to a test case method 

 * on a test case class.  Test callers are useful when 

 * you want to run an individual test or add it to a suite.

 * 

 * Here is an example:

 * 

 * class CMathTest : public CTestCase 

 * {

 *     public:

 *         void         setUpL ();

 *         void         tearDown ();

 *

 *     protected:

 *         void         testAddL ();

 *         void         testSubtractL ();

 * };

 *

 * CTest* CMathTest::suiteL () 

 * {

 *     CTestSuite *suite = CTestSuite::NewL();

 *     suite->addTestL(CTestCaller<MathTest>::NewL(_L("testAddL") testAddL));

 *     suite->addTestL(CTestCaller<MathTest>::NewL(_L("testSubtractL") testSubtractL));

 *     return suite;

 * }

 *

 * You can use a CTestCaller to bind any test method on a CTestCase

 * class, as long as it does not have parameters and returns void.

 * 

 * See CTestCase
