So the other day, while listening to Testing in the Pub with Keith Klain, as it happens, a thought that made me chuckle popped into my head. And when, an hour or two later, I was still chuckling, I tweeted it.

The tweet format can be a sweet format because the detail is left to the reader’s imagination. But I wanted to add a couple of notes.

The term is a pun on technical debt:

In this metaphor, doing things the quick and dirty way sets us up with a technical debt, which is similar to a financial debt. Like a financial debt, the technical debt incurs interest payments, which come in the form of the extra effort that we have to do in future development because of the quick and dirty design choice. 

And, while the tweet is funny because we’ve all felt that kind of pain due to that kind of debt in our testing effort at some point (and because testicles are just inherently funny), it fails to acknowledge an extremely important point.

Sure, we have to prioritise testing work, like pretty much all other work. Sometimes the work we don’t do turns out to have been important. Sometimes we suffer because of that. Often this is because the assumptions we held when prioritising were incorrect, or circumstances have changed and they are no longer valid.

But – and this is the important point – sometimes that is also true of the work we did do.  Every action we take is a gamble. Sometimes it will pay off, and sometimes it won’t, as I somehow found myself telling *cough* Kent Beck recently.
