These aren't the bugs you were looking for

How many times have we run a testing session to discover a bug we just had no intention of or idea that we might discover it? The joys of testing, right? Some of my favourites are when you're retesting a bug fix and another bug pops up to say hi. Hello little bug! There have also been times in my career when I've worked with a developer who was so good at convincing me that I hadn't discovered a bug. It was a real Jedi skill. I'd walk back to my desk, confused and convinced it was a bug whilst also questioning my testing skills.
