I believe the complaint here lies in the semantic ambiguity of "the test failed". Does that mean the test 1) was improperly designed such that it could not possibly prove that which it was commissioned to prove (test design was sound/flawed) or 2) was perfectly designed, the proof of which is that a failure mode of the device being tested was demonstrated (test device passed/failed)
As an engineer I take great pains to say what I mean as unambiguously as possible, because I know that failures happen quite often due to miscommunication. I read the summary above and am left in no doubt what happened, without even having seen the test results.
What I find truly interesting is how many people, upon seeing a test that passed all of the designed criteria say "the test passed" rather than either "the test was unnecessary" or "the test was insufficiently comprehensive". There are no flawless systems. If your test didn't result in some kind of failure you should immediately question whether you designed your tests correctly.
