Factor Language Blog

The Factor core consists of 34,000 lines of Factor code. The test suite used to test the core is just a dozen or so unit tests shy of 2000. I don’t know if this is considered enough tests or not, but it sure seems like a lot. Lately I’ve been working on the UI and trying to unit test every new feature and fix I apply. This is a bit difficult and has required some refactoring, but I think it is worth it.
