| /** |
| * SwingTest is a utility class for writing regression tests |
| * that require interacting with the UI. |
| * It uses reflection to invoke all public methods without parameters. |
| * All static methods are starting on the current thread. |
| * Other methods including constructor are starting on the EDT. |
| * Between each method invocation all pending events are processed. |
| * The methods are sorted by name and invoked in that order. |
| * Failure of the test is signaled by any method throwing an exception. |
| * If no methods throw an exception the test is assumed to have passed. |
