how to make an ActivityUnitTestCase that depends on a ContentProvider use test databases
@Override
protected void setUp() throws Exception {
super.setUp();
// Create a Context for our content provider that will use the test.*
// database instead of the production database
final String filenamePrefix = "test.";
final RenamingDelegatingContext testDatabaseContext = new RenamingDelegatingContext(
getInstrumentation().getTargetContext(), getInstrumentation()
.getTargetContext(), filenamePrefix);
// Instantiate our content provider and make it use the Context created
// above
mProvider = new MyContentProvider();
mProvider.attachInfo(testDatabaseContext, null);
final boolean onCreate = mProvider.onCreate();
assertTrue("ContentProvider reported failure in onCreate()", onCreate);
// Create a mock ContentResolver that will give access to our content
// provider and nothing else
mResolver = new MockContentResolver();
mResolver.addProvider(MyContentProvider.AUTHORITY, mProvider);
// Create a Context for our activity under test that will use our
// content resolver (and thus our content provider), and will otherwise
// behave as the normal Context for an ActivityUnitTestCase
mActivityContext = new ContextWrapper(getInstrumentation()
.getTargetContext()) {
@Override
public ContentResolver getContentResolver() {
return mResolver;
}
};
setActivityContext(mActivityContext);
