In our previous post, we talked about the Android Studio and Java Installation. In this we will learn about very famous unit testing framework setup for android studio that is Junit. Before jumping on to the setup let us learn more about Junit Testing Framework.

What is Junit ?

Junit is a widely used testing framework used for Java Programming language. Before you learn, how to write automated test cases it is very important to learn Junit testing framework in detail. It helps you to define the flow of your testing framework.
Junit is built on idea of “first testing and then coding” which helps in increasing productivity of the test case developer and stability of the code.

Features of Junit Testing –
