testTrapFork

Fork the current test program to execute a test case that might not return or that might abort.

If @usec_timeout is non-0, the forked test case is aborted and considered failing if its run time exceeds it.

The forking behavior can be configured with the #GTestTrapFlags flags.

In the following example, the test code forks, the forked child process produces some sample output and exits successfully. The forking parent process then asserts successful child program termination and validates child program outputs.

| static void test_fork_patterns (void) { if (g_test_trap_fork (0, G_TEST_TRAP_SILENCE_STDOUT | G_TEST_TRAP_SILENCE_STDERR)) { g_print ("some stdout text: somagic17\n"); g_printerr ("some stderr text: semagic43\n"); exit (0); // successful test run } g_test_trap_assert_passed (); g_test_trap_assert_stdout ("*somagic17*"); g_test_trap_assert_stderr ("*semagic43*"); } |
