|
| 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 | *
