In recent years OOP world started to embrace more and more functional ideas. Immutability, lambdas, functions as first class citizens etc., so I think it’s a good time to take a look on another functional idea: Property based testing. We test on every level, writing a lot of unit, integration, e2e etc tests. It’s repetetive and boring, but very useful. But with all this test coverage - we still get errors. Can we protect ourselves from hard-to-find bugs? Can testing be less time consuming? In this talk I’ll show other way of writing tests that will answer those questions.
