Property-based testing is mainstream now (there, I said it). The testing approach popularised by test.check enjoys wide adoption in the Clojure community. This talk is dedicated to another randomised testing technique. Mutation testing introduces subtle bugs to source code of our projects and checks that our tests catch those synthetic problems. Clojure — a homoiconic language with dynamic code reloading — should offer us an excellent foundation for building a mutation testing library. But there’s not a single one out there. Why? Let’s try to answer this question together.
A video of this talk is now available here.
