Junit 5 is the de-facto standard testing framework on the JVM. It is used to test application code in many areas including enterprise, desktop and mobile applications. This class will show how to setup Junit to test Kotlin code, including the some of the issues you will encounter that are unique to Kotlin. The class will also extend some of the features of Junit, for example by using an assertions library to extend the range and flexibility of the assertions that are available. Finally we will look at ‘mocking’, something that JUnit does not provide itself, for this we will use the MockK, a mocking framework written in and for Kotlin.
