I think the intent was that if either one or the other didn't work then report a failure. Because of the included four test cases that showed all four of the possibilities. Your test here changes that behavior. As to whether this is a good idea to do it one way or the other way is a different question. As to whether it should be the other way around with a success being if either ping succeeds that I don't know. I am not sure what this test is being used for. But it is a different test. Bob
