/**

abstract  public class BaseMyContentProviderTestCase extends ProviderTestCase2<MyContentProvider> {
    private static final String TAG = BaseMyContentProviderTestCase.class.getSimpleName();

        // initialize SQLCipher with correct Context and file path for these tests
        SQLiteDatabase.loadLibs(getMockContext(),
                getMockContext().getDatabasePath(MyDatabaseHelper.DB_NAME).getParentFile());

        // make sure SyncAdapter doesn't try to run
        ContentResolver.cancelSync(SyncAdapter.getAccount(getMockContext()),
                MyContentProvider.AUTHORITY);

        // wait here until SyncAdapter finishes (or we will get a ReadOnlyDatabaseException after
        // due to the :sync process accessing at the same time)
        boolean isSyncing;
        do {
            isSyncing = false;
            for (SyncInfo syncInfo : ContentResolver.getCurrentSyncs()) {
                if(syncInfo.authority.equals(MyContentProvider.AUTHORITY)) {
                    isSyncing = true;
                    break;
                }
            }
            Thread.sleep(10);
        } while(isSyncing);
    }

    @Override
    protected void tearDown() throws Exception {
        super.tearDown();

        getMockContext().getDatabasePath(MyDatabaseHelper.DB_NAME).delete();
    }
}

One issue to tackle, the above stops an ongoing SyncAdapter and waits for it to finish before running the next test. Debugging shows it is running on start due to the setSyncAutomatically() in the Application setup. But technically it could also start again during the test (e.g. due to network "tickle") as it's a different process. Need to permanently disable automatic syncing once it's been set without side effects.
