What's the one missing detail that usually makes a bugs hard to debug?
When debugging issues in UAT, what information do you end up recreating by hand?
Logs, state, timing, data, versions, or something else?
My biggest roadblocks come from my own certainty that I wrote correct code. That leads me to look in the wrong places for the bug. I have repeatedly looked right at bugs and not seen them because I felt sure that code works as expected.
