Tests in Android Studio IntellJ

Setup Unit & Component tests (Robolectric)

Unit and component test will need different classpath with an entry to compiled test classes.

1. Start a test and you will get error like:

/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bin/java ...
Class not found: "com.example.activities.MainActivityTest"
Process finished with exit code 1

2. From the first line copy the -classpath "..." part to an editor
3. Append missing class and resource locations at end of classpath
   • absolute-path-to-test-module/build/resources/testDebug
   • absolute-path-to-test-module/build/test-classes/debug
4. Edit your run configuration
   • VM options: Paste here your modified classpath
   • Working directory: $MODULE_DIR$
   • Before launch -> Add -> Run External Tool -> Add
     • Program: ../gradlew
     • Parameters: processTestDebugResources testDebugClasses
     • Working directory: $ModuleFileDir$

Finish, now your test should run. This must be repeated when classpath changes occur (e.g add new dependency).

!!! JUnit version 3.8 or later expected: java.lang.RuntimeException: Stub!
```
When it occur, make the junit4 classpath entry as the first entry in that classpath.
