How and Where to add Test cases in Android Studio?

There are some specific rules for writing test folder in android studio related to project structure and hierarchy. In case of Espresso, Robotium and UIautomator we need to write instrumentation test cases which will be written in androidTest folder of the project. Let us see how to create that folder.

1. In android studio it is important to write instrumented functional test cases in src/androdTest/java folder and unit tests in src/Test/java.

2.Now we need to create androidTest folder. right click on the src -> New ->Folder ->Java folder

3. Click on Change Folder Location and add location src/androidTest/Java

4.  Right click on java -> New -> Package and the enter package name

5. Once the package is created then right click on the package name -> New -> Java Class give Class Name TestClass  and click on OK.

After creating the TestClass you are ready to start writing your test cases.
