testFailed
Returns whether a test has already failed. This will be the case when g_test_fail(), g_test_incomplete() or g_test_skip() have been called, but also if an assertion has failed.
This can be useful to return early from a test if continuing after a failed assertion might be harmful.
The return value of this function is only meaningful if it is called from inside a test function.
Return
