4 * \brief Utility macros/functions for testing and debugging purpose.
5 *
6 * Basic usage:
7 * <pre>
8 * BOOST_UBLAS_TEST_DEF( test_case_1 )
9 * {
10 * // do your test stuff
11 * }
12 *
13 * BOOST_UBLAS_TEST_DEF( test_case_2 )
14 * {
15 * // do your test stuff
16 * }
17 *
18 * // ...
19 *
20 * BOOST_UBLAS_TEST_DEF( test_case_n )
21 * {
22 * // do your test stuff
23 * }
24 *
25 * int main()
26 * {
27 * BOOST_UBLAS_TEST_SUITE( "My Test Suite" ); // optional
28 *
29 * BOOST_UBLAS_TEST_BEGIN();
30 * BOOST_UBLAS_TEST_DO( test_case_1 );
31 * BOOST_UBLAS_TEST_DO( test_case_2 );
32 * // ...
33 * BOOST_UBLAS_TEST_DO( test_case_n );
34 * BOOST_UBLAS_TEST_END();
35 * }
36 * </pre>
37 * Inside each <em>test_case_<code>k</code></em> you can use the various
38 * \c BOOST_UBLAS_TEST_CHECK* macros.
