Pure Kotlin Unit Testing — Part 1
Write once, test everywhere
Introduction
JetBrains has introduced a test framework that allows developers to write pure Kotlin Unit Test.
In the past you probably used JUnit, which is a test framework base on Java (yes that’s the “J” in JUnit).
By introducing this test framework, JetBrains allows us to write Unit Tests that are working cross platform. This is obviously serving the cause of Kotlin Multiplatform, also known as “KMM”.
Importing the Kotlin test framework
First things first, we need to import the new framework into our Android or Multiplatform project.
in your build.gradle.kts, dependencies section:
implementation(kotlin("test-common"))
implementation(kotlin("test-annotations-common"))Getting familiar with Kotlin test framework
While the framework is very similar to JUnit, they are some differences that worth to highlight.
The @BeforeTest and @AfterTest annotations
The @BeforeTest annotation will help you to setup the pre-requisites before each test (of your test suite).
The @AfterTest annotation will help clearing anything after each test (of your test suite)
