Learning Concurrency in Kotlin

Adding the kotlin-test library

The first step is to add the required dependencies to our project. The kotlin-test library provides annotations and base implementations for tests and assertions. Let's go to the build.gradle file and append the lines in bold:

dependencies {    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"    compile "org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutines_version"    // Test libraries    testCompile "org.jetbrains.kotlin:kotlin-test"    testCompile "org.jetbrains.kotlin:kotlin-test-junit"}

Once the changes are applied, we will be able to start writing our Functional Tests.

We are using the standard testing library for Kotlin because I don't want the book to include third-party libraries unless needed. ...
