Android, Junit and testPreconditions()

问题:

I'm trying to do some tests on my application's database. I only got one activity in my application ("Home") so my test class is
public class HomeTest extends ActivityInstrumentationTestCase2 {..}

My troubles :

1) In Android developers I've seen that testPreconditions() method is supposed to be launch before all tests, but in my app, it's acting like a normal test ...

2) I'd like to fill my database before all other tests to begin. But to do so, I need a reference on my Activity, but I can't call "this.getActivity" in the tests constructor ... Is there a way to do something after the constructor ? (The setUp() method isn't appropriate, because it is called before each test, not just one time before all)

Thanks

1. The order in which the test are run is not guaranteed to run before other tests, as junit 3 uses reflection to find the tests.

2. Use the setUp() method, this also assure that your tests run with a fresh database
