But does such a test have any actual value? If your test infrastructure
ignores the result, what makes you think you'd notice if the test did
indeed detect a problem?
I think "ignore:" was a kluge we put in twenty-plus years ago when our
testing standards were a lot lower, and it's way past time we got
rid of it.
