Test driven development of concurrent programs in Kotlin at KKon 2022

Concurrent and asynchronous applications can be written in Kotlin with coroutines in a precise and structured way. Unfortunately, concurrency often increases the complexity and it is difficult to create bug-free and maintainable programs.

In my talk “Korrekte nebenläufige Anwendungen mit Koroutinen und TDD” at the KKon 2022 I show that test-driven development (TDD) is a solution.
