Yesterday, I had a smugness related disaster.

I’d very confidently checked in a new feature, declaring to the world around me how confident I was it was working.

‘I’ve got loads of unit tests’, I said.

‘You’ll hardly have to manual test it at all’, I said.

Failed the first manual test when a checkbox worked exactly backwards.

Turned out I had got those unit tests exactly backwards, then wrote code to make them pass.

D’Oh !

So the repeating fault here would be my hubristic tendency to feel a bit smug from time to time
