@Dan I’ve heard that very same line, my response at the time, “Seeing is believing, so watch the system as it goes ‘ka…booom’ when…”.
@Stefan isn’t that the most common line we are faced with? 🙂 It sure demand from us, to a certain extent, improving the quality of the evidence we provide in the bug report, making that line a futile attempt for not wanting to fix it. Particularly, it’s been quite useful employing a scenario based approach to write the defects.
One common line I’ve heard from developers “Hey, don’t take this personal, but for so long as we do unit testing… we can leave QA out of the business”.
By the way, the following is not a phrase from a developer, but one from a fellow tester with whom I worked for some time: “A tester should have the heart of a developer… on a table, inside a jar.” 😀 What do you think about it?
