| /** |
| * <b>Purpose:</b> Allow for very simple Unit tests. |
| * |
| * The drawback with the current test framework is that because each test case |
| * corresponds 1-1 to a java class, in the worst case there will be one java |
| * class for each test case. |
| * <p> |
| * This can be alleviated by writing generic test cases, (i.e. that take many |
| * parameters), or in the worst case testing many things with a single test |
| * case / java class. The latter is messy and the former works well with |
| * functional tests (where you can execute the same code but in different |
| * ways), but is fairly useless when it comes to Unit testing. How for example |
| * can one write a generic test case for testing getters and setters? |
| * <p> |
| * A unit test can be added to any TestSuite, and works well when setup/reset is |
| * extremely simple or not required, and the test method itself is only a couple |
| * of lines long. In this case the entire test itself is just a method in |
| * that TestSuite, named _test{TestName}. |
| * <p> |
| * <b>Example:</b> To add a test called CreateTest, to test Expression.create(), |
| * define a method called _testCreateTest in ExpressionUnitTestSuite, |
| * and in addTests call: |
| * addTest(new UnitTestCase("CreateTest")); |
| * When the test is executed ExpressionUnitTestSuite setup() and reset() |
| * will be called, along with _testCreateTest(). |
| * |
| * @since 9.0.4 |
