It does. But the person responsible for evaluating it was on their way out (had gotten a new job, hadn't put in their notice yet though) and just said, "All good!" to a bunch of things (previously trustworthy and good work, but their work that last month or two was shit).

So to some extent the dev got unlucky, his terrible code (that he didn't test) may have been caught through the normal QA process which the QA willfully lied about doing. But that doesn't absolve him for not testing (even basic testing) his own work.

Do you imagine QA catches everything?
