    A useful general test case class, especially if you are

    just starting out with Android testing, is {@link android.test.AndroidTestCase}. It extends

    both {@link junit.framework.TestCase} and {@link junit.framework.Assert}. It provides the

    JUnit-standard <code>setUp()</code> and <code>tearDown()</code> methods, as well as well as

    JUnit-standard <code>setUp()</code> and <code>tearDown()</code> methods, as well as

    all of JUnit's Assert methods. In addition, it provides methods for testing permissions, and a

    method that guards against memory leaks by clearing out certain class references.

    Mock objects isolate tests from a running system by stubbing out or overriding

    normal operations. For example, a {@link android.test.mock.MockContentResolver}

    replaces the normal resolver framework with its own local framework, which is isolated

    from the rest of the system. MockContentResolver also also stubs out the

    from the rest of the system. MockContentResolver also stubs out the

    {@link android.content.ContentResolver#notifyChange(Uri, ContentObserver, boolean)} method

    so that observer objects outside the test environment are not accidentally triggered.
