Designing a DSL with Kotlin

English session - Beginner

Kotlin is one of those “new” JVM languages that are currently rocking the boat. Although it’s made a great impact on Android, it’s equally good on the server side.

I'll explain how Code Coverage is computed and what its inherent flaw is. Afterwards, I'll describe how Mutation Testing work and how it helps pointing out code that leaves out corner cases. I will also demo PIT, a Java production-grade framework that enables Mutation Testing.
