Delivering the required functionality
- more time for cleaning up our code base
- getting up to speed the latest development in tools an technology

5. Running tests on an Android
emulator or device is slow!
Building, deploying, and launching
the app often takes a minute or
more. That’s no way to do TDD.
There must be a better way.

7. Robolectric is a unit test framework that de-fangs the Android SDK jar so you can
test-drive the development of your Android app. Tests run inside the JVM on your
workstation in seconds

8. Java
Project
Android.jar
Robolectric
.xxx.jar

9. Run Tests Outside of the Emulator
No Dexing
No Packaging
