The topic for today is writing automation test scripts in Java. For your information, test automation is a technique that utilizes automation tools to control the execution of tests. This comes in handy as it enables you to execute the test on each commit or after a big update.

Test automation helps improve the efficiency and accuracy of your system. Besides, it also alleviates most of the tedious efforts that you need to take to manually debug and test your app.

This tutorial focuses on JUnit5, a full-fledged testing framework, which is composed of several different modules from three different sub-projects:

• JUnit Platform: a foundation for launching testing frameworks on JVM. It provides support for most of the popular IDEs (IntelliJ IDEA, Eclipse, NetBeans, and Visual Studio Code) and build tools (Gradle, Maven, and Ant).
• JUnit Jupiter: a new programming model for test automation in JUnit5
• JUnit Vintage: a backward-compatible test engine which supports running JUnit3 and JUnit4 tests

Let’s proceed to the next section and start writing your test in Java.
