This project was originally called Testacular. I was little confused at first, thinking it was a late and flat April fool's joke.

Great. The name alone has stopped me from using it.

And here is where the decision was made to rename it: https://github.com/karma-runner/karma/issues/376

Wow. My humor is pretty crude but I'd never made the connection to testicles before. I'd just assumed it was a portmanteau of "test" and "spectacular" but I am British and the latter word still sees some usage ;-)

As an American it took... perhaps 5 minutes or so to scratch my head at the name :).

Yup. If you look at the docs, they haven't finished renaming it yet. They seem to be using 'karma' and 'testacular' interchangeably.

Pity, Testacular was such a ballsy name.

Very cool project. Nothing like having your tests run every time you save a file... in several different browsers if you like. This and docco made me think about about node differently. Though it is a server side JavaScript framework, it has also become a platform for developer automation tasks.

I believe one of the guys behind this is Misko Hevery (of AngularJS). He's test-driven mad (which is a good thing IMO). I've been meaning to try Testacular / Karma out just because of the pedigree.

Autorunning tests is cool, and great for TDD. I usually just use Guard for that, but I can understand why they would build their own thing to suit their needs better.
