Having established what tests can actually be good for, outlined the only two types of test that matter and their value, and having attempted to make the case against a narrow fixation on “unit tests”, where does that leave us?

Well, it leaves us free to think about how we can write good tests that are useful and practical! And the . . .

We Think About Code Too Much

June 09, 2015

Yesterday, during the lead up to the WWDC keynote, I started thinking about what really matters the most when it comes to software engineering.
