Love this. Sometimes testing can be a huge pain in the ass. I know more than one project I work on where getting them to run is a lot of effort in itself.

There is something to be said about code quality and having tests run in under a few seconds. The ideal situation is when you can have a barrage of tests run as fast as you are making changes to code. If we ever got to the point of instant feedback that didn't suck I'd think we'd change a lot about how we think about tests.
