Part 6
Interop and Testing

Having looked at the core capabilities of the language, let’s now turn our attention to applying Kotlin. In this part, you’ll learn how to use Kotlin with Spring and to create Android applications. You’ll also learn how to use Kotlin with Gradle and Maven and, along the way, pick up some techniques for unit testing Kotlin code with tools like KotlinTest and Mockk. We’ll also explore the options to interoperate between Java and Kotlin code running side by side.
