| 24 | * |
| 25 | * This file provides implementation of \b exception_test(). It tests the |
| 26 | * functionality of the exception handling API. |
| 27 | * |
| 28 | * @note This test use static ID not acquired through proper registration. |
| 29 | * This is not recommended, since it may create ID collissions. |
| 30 | * |
| 31 | * \section exception_test_sec Scope of the Test |
| 32 | * |
| 33 | * Some scenarios tested: |
| 34 | * - no exception situation |
| 35 | * - basic TRY/CATCH |
| 36 | * - multiple exception handlers |
| 37 | * - default handlers |
| 38 | * |
