I have a wide range of techniques for testing code behavior. I can reliably increase quality over time no matter how large the feature set grows and even measure the completeness of my test suite (mutation testing). The same can’t be said for UIs. I have long struggled to automate UI tests at all, and manual tests don’t sustain as the system grows. However, I think I may now have a technique to close the gap.
Fred Brooks once described elegant design as few ideas combined powerfully. Clojure is a language that lives by that idea. Understanding Clojure improved my understanding of language choices in general. Here I’ll highlight some of my learnings.
I absolutely love Scott Wlaschin’s work. He breaks down the unfamiliar and sometimes complex ideas of functional languages into approachable explanations. My one gripe with his site is that there is a bit of an implicit order to the content. Here’s my outline of how I think the concepts best build on each other.
