7 * \page page_pjlib_exception_test Test: Exception Handling
8 *
9 * This file provides implementation of \b exception_test(). It tests the
10 * functionality of the exception handling API.
11 *
12 * @note This test use static ID not acquired through proper registration.
13 * This is not recommended, since it may create ID collissions.
14 *
15 * \section exception_test_sec Scope of the Test
16 *
17 * Some scenarios tested:
18 * - no exception situation
19 * - basic TRY/CATCH
20 * - multiple exception handlers
21 * - default handlers
22 *
23 *
24 * This file is <b>pjlib-test/exception.c</b>
25 *
26 * \include pjlib-test/exception.c
