3. Agenda •  Why testing? •  Types of tests •  What to test on Android •  Tools for testing – JUnit – Mockito – Robolectric – Test Framework  
4. Why testing? •  Testing increases the level of confidence in your code. •  Testing makes it possible to write new code, and refactor existing code, without worrying that you’ve broken existing functionality.
5. Types of Tests
6. Testing on Android… Tools… •  Junit •  Mockito •  Robolectric •  Test Framework
7. JUnit •  JUnit is an open source framework that has been designed for the purpose of writing and running unit tests in Java.
8. Mockito •  Mocking Frameworks allow us to test the code you want, without its dependencies. •  Mock objects can simulate the behaviour of complex objects. •  Mock objects isolate the unit of code you are testing.
9. Code Sample
10. Robolectric •  Robolectric is a unit test framework that de-fangs the Android SDK jar so you can test-drive the development of your Android app. •  It rewrites Android SDK classes as they're being loaded and making it possible for them to run on a regular JVM.
11. Code Sample
12. Android Test Framework •  Offered by the android framework. •  Needs an emulator to execute the tests •  Lets write unit, integration and functional tests. •  Has its own mocking framework
13. Code Sample
14. More tools… •  Fest •  Spoon •  Robotium •  UI Automator •  Monkey Runner •  Strict Mode
15. Some useful concepts… •  Dependency Injection •  Code coverage •  Continuous Integration
16. Conclusion There is virtually no reason why you should not be testing.
17. Any questions?
