4. Android testing
How do we write tests for Android?

5. Android testing
As usual! Android uses JUnit 3
android.test:
AndroidTestCase < junit.framework.TestCase
InstrumentationTestCase < junit.framework.TestCase

6. Android testing
AndroidTestCase
ApplicationTestCase
ProviderTestCase2
ServiceTestCase

7. Android testing
InstrumentationTestCase
(SyncBaseInstrumentation)
(SingleLaunchActivityTestCase)
ActivityUnitTestCase
ActivityInstrumentationTestCase2

8. Android testing
How do we run tests for Android?

9. Android testing
Using Instrumentation.

10. Android testing
Work it!

11. Build management
Nice, we have tests now.
But my build server
doesn't click buttons.

12. Build management
We need something that can run
builds from the command line.

13. Build management
Maven 2 does these sorts of things.
(and MUCH more, in fact)

14. Build management
Maven 2 is a build system.

15. Build management
Maven 2 is a dependency
management system.

16. Build management
Maven 2 is a life-cycle
management system.

17. Build management
Maven 2 is a report and
documentation generator.

18. Build management
In fact: Maven 2 is a platform.

19. Build management
There's a plugin for Android!
maven-android-plugin

20. Build management
Maven's central notion is the project.
It's described by the POM.

21. Android testing
Let's have a look at one...

22. Build automation
Nice, we can now build and deploy our
app from the command line.
But we still have to do it manually.

23. Build automation
What we need is a build server, which
automatically triggers builds.

24. Build automation
Hudson does these sorts of things.

25. Build automation
Hudson is a continuuous integration server. It can
run builds when people commit pieces of work.
This is extremely helpful for discovering
software regressions early on.

26. Build automation
Hudson is a Java Web application.
It consists of a single WAR.
$ java -jar hudson.war

27. Build automation
Let's run it.
