How to set up Android Studio for Unit Testing. Works in version 1.0 and up.

android-studio-unit-test-setup

In Android Studio 1.0 the scheme has changed a little bit.

The path to a unit test source file should be (app)/src/androidTest/java/com/mycompany/myapp/HelloWorldTest.java

Here's how I set up Unit Tests in a new Android Studio project:

- Open app in Android Studio.
- Set the Project explorer (left hand window) to display 'Project' mode. Tap the little drop-down at the top left and select 'Project'.
- Right click the 'src' directory, 'New -> Directory'.
- Call new directory androidTest
- Right click androidTest and add a 'java' directory. It will appear in green (indicating it's a test src directory).
- Now right-click again and add a package, e.g. com.mycompany.myapp.tests
- Add a new class that extends AndroidTestCase.

Now add a new configuration for testing:

- Edit Configurations
- Click + at top left
- Select Android Tests
- In General Tab select your main module.
- Hit OK

Now you can run the tests.
