ProviderTestCase2

public abstract class ProviderTestCase2 extends AndroidTestCase
This TestCase class provides a framework for isolated testing of a single ContentProvider. It uses a {@link android.test.mock.MockContentResolver} to access the provider, restricts the provider to an isolated area of the filesystem (for safely creating & modifying databases & files), and injects {@link android.test.IsolatedContext} to isolate the ContentProvider from the rest of the running system.

This environment is created automatically by {@link #setUp} and {@link #tearDown}.
