Best Practices for Unit Testing in Kotlin
Philipp Hauer's Blog Engineering Management, Java Ecosystem, Kotlin, Sociology of Software Development Posted on Feb 12, 2018. Updated on Jun 12, 2022 Unit Testing in Kotlin is fun and tricky at the same time. We can benefit a lot from Kotlin’s powerful language features to write readable and concise unit tests. But in order to write idiomatic Kotlin test code in the first place, there is a certai

Using Kotlin For Tests in Android
Many developers are quite optimistic about Kotlin future for Android. It sounds so sweet: less verbose, more type-safety, zero-overhead null-safety, Java interop. But not everyone is ready to take a risk and start writing production code using new programming language. Indeed, it could be not mature enough and will add dependencies which increase method count of APK for more than 6.5K. But what if
