copied!<blockquote> <p>We started some work with CUnit, which worked except that everything ran in one thread and any memory faults caused the unit tests to stop running, which was rather annoying. </p> </blockquote> <p>There one C unit testing framework that forks and executes each test cases in a separate process so that all the tests are executed even in the presence of tests that core dump : <a href="http://sourceforge.net/projects/check/" rel="nofollow noreferrer">Check</a> </p> <p>However, I'm afraid of the performance penalty all these forks bring (and to be honest, I didn't give it a try). But I won't live long with any single test core dumping : I usually fix it immediately. </p> <p>One trick to prevent the unit tests to core is the <strong><a href="http://xunitpatterns.com/Guard%20Assertion.html" rel="nofollow noreferrer">assertion guard</a></strong>, for instance: use an assertion to prevent using a NULL pointer (example with <a href="http://www.jera.com/techinfo/jtns/jtn002.html" rel="nofollow noreferrer">minunit</a>). </p> <pre><code>void test_function_returning_a_pointer(void) { struct_t *theStruct = function_returning_a_pointer(); MU_ASSERT(theStruct != NULL); //--- now you can use the pointer MU_ASSERT(theStruct->field1 == 0); return MU_PASSED; } </code></pre> <p>By the way, I'm not aware of any C++ unit test framework that won't crash in case of segmentation violation.</p> <blockquote> <p>I also found it incredibly difficult to write the tests, but that might just be unit testing for you.</p> </blockquote> <p>Could you elaborate on your difficulties ? Are you trying to put legacy code under tests ?</p>
