/*

 * A test case defines the fixture to run multiple tests. To define a test case

 * 1) implement a subclass of CTestCase

 * 2) define instance variables that store the state of the fixture

 * 3) initialize the fixture state by overriding setUp

 * 4) clean-up after a test by overriding tearDown.

 *

 * Each test runs in its own fixture so there can be no side effects 

 * among test runs. Here is an example:

 * 

 * class CMathTest : public CTestCase 

 * {

 *     public:

 *

 *     void setUpL () 

 *     {

 *         iValue1 = 2;

 *         iValue2 = 3;

 *     }

 *     

 *     private:

 *

 *     TInt iValue1, iValue2;

 * }

 * 

 * For each test implement a method which interacts with the fixture.

 * Verify the expected results with assertions specified

 * by calling assert on the expression you want to test:

 * 

 *    protected: 

 *    void testAddL ()

 *    {

 *        TInt result = value1 + value2;

 *        assertL (result == 5);

 *    }

 * 

 * The tests to be run can be collected into a CTestSuite:

 * 

 * public: 

 * static CMathTest::suiteL ()

 * {

 *      CTestSuite *suiteOfTests = CTestSuite::NewL(_L8("aSuite"));

 *      suiteOfTests->addTestL(CTestCaller<MathTest>::NewL(_L8("testAddL"), testAddL));

 *      return suiteOfTests;

 * }

 *

 * see CTestSuite and CTestCaller

 *
