 /**
- * 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.
- *
- * <p>This environment is created automatically by {@link #setUp} and {@link
- * #tearDown}.
+ * This test case class provides a framework for testing a single
+ * {@link ContentProvider} and for testing your app code with an
+ * isolated content provider. Instead of using the system map of
+ * providers that is based on the manifests of other applications, the test
+ * case creates its own internal map. It then uses this map to resolve providers
+ * given an authority. This allows you to inject test providers and to null out
+ * providers that you do not want to use.
+ * <p>
+ *      This test case also sets up the following mock objects:
+ * </p>
+ * <ul>
+ *      <li>
+ *          An {@link android.test.IsolatedContext} that stubs out Context methods that might
+ *          affect the rest of the running system, while allowing tests to do real file and
+ *          database work.
+ *      </li>
+ *      <li>
+ *          A {@link android.test.mock.MockContentResolver} that provides the functionality of a
+ *          regular content resolver, but uses {@link IsolatedContext}. It stubs out
+ *          {@link ContentResolver#notifyChange(Uri, ContentObserver, boolean)} to
+ *          prevent the test from affecting the running system.
+ *      </li>
+ *      <li>
+ *          An instance of the provider under test, running in an {@link IsolatedContext}.
+ *      </li>
+ * </ul>
+ * <p>
+ *      This framework is set up automatically by the base class' {@link #setUp()} method. If you
+ *      override this method, you must call the super method as the first statement in
+ *      your override.
+ * </p>
+ * <p>
+ *     In order for their tests to be run, concrete subclasses must provide their own
+ *     constructor with no arguments. This constructor must call
+ *     {@link #ProviderTestCase2(Class, String)} as  its first operation.
+ * </p>
+ * For more information on content provider testing, please see
+ * <a href="{@docRoot}guide/topics/testing/provider_testing.html">Content Provider Testing</a>.

- * Service, and hooks by which you can inject various dependencies and control
+ * Service, and hooks with which you can inject various dependencies and control
  * the environment in which your Service is tested.
  *
  * <p><b>Lifecycle Support.</b>
- * Every Service is designed to be accessed within a specific sequence of
- * calls.  <insert link to Service lifecycle doc here>. 
- * In order to support the lifecycle of a Service, this test case will make the
- * following calls at the following times.
+ * A Service is accessed with a specific sequence of
+ * calls, as documented in the section
+ * <a href="http://developer.android.com/guide/topics/fundamentals.html#servlife">
+ * Service lifecycle</a> in the Developer Guide. In order to support the lifecycle of a Service,
+ * <code>ServiceTestCase</code> enforces this protocol:
  *
- * <ul><li>The test case will not call onCreate() until your test calls 
- * {@link #startService} or {@link #bindService}.  This gives you a chance
- * to set up or adjust any additional framework or test logic before
- * onCreate().</li>
- * <li>When your test calls {@link #startService} or {@link #bindService}
- * the test case will call onCreate(), and then call the corresponding entry point in your service.
- * It will record any parameters or other support values necessary to support the lifecycle.</li>
- * <li>After your test completes, the test case {@link #tearDown} function is
- * automatically called, and it will stop and destroy your service with the appropriate
- * calls (depending on how your test invoked the service.)</li>
+ * <ul>
+ *      <li>
+ *          The {@link #setUp()} method is called before each test method. The base implementation
+ *          gets the system context. If you override <code>setUp()</code>, you must call
+ *          <code>super.setUp()</code> as the first statement in your override.
+ *      </li>
+ *      <li>
+ *          The test case waits to call {@link android.app.Service#onCreate()} until one of your
+ *          test methods calls {@link #startService} or {@link #bindService}.  This gives you an
+ *          opportunity to set up or adjust any additional framework or test logic before you test
+ *          the running service.
+ *      </li>
+ *      <li>
+ *          When one of your test methods calls {@link #startService ServiceTestCase.startService()}
+ *          or {@link #bindService  ServiceTestCase.bindService()}, the test case calls
+ *          {@link android.app.Service#onCreate() Service.onCreate()} and then calls either
+ *          {@link android.app.Service#startService(Intent) Service.startService(Intent)} or
+ *          {@link android.app.Service#bindService(Intent, ServiceConnection, int)
+ *          Service.bindService(Intent, ServiceConnection, int)}, as appropriate. It also stores
+ *          values needed to track and support the lifecycle.
+ *      </li>
+ *      <li>
+ *          After each test method finishes, the test case calls the {@link #tearDown} method. This
+ *          method stops and destroys the service with the appropriate calls, depending on how the
+ *          service was started. If you override <code>tearDown()</code>, your must call the
+ *          <code>super.tearDown()</code> as the last statement in your override.
+ *      </li>
  * </ul>
- * 
- * <p><b>Dependency Injection.</b>
- * Every service has two inherent dependencies, the {@link android.content.Context Context} in
- * which it runs, and the {@link android.app.Application Application} with which it is associated.
- * This framework allows you to inject modified, mock, or isolated replacements for these 
- * dependencies, and thus perform a true unit test.
- * 
- * <p>If simply run your tests as-is, your Service will be injected with a fully-functional
- * Context, and a generic {@link android.test.mock.MockApplication MockApplication} object.
- * You can create and inject alternatives to either of these by calling 
- * {@link AndroidTestCase#setContext(Context) setContext()} or 
- * {@link #setApplication setApplication()}.  You must do this <i>before</i> calling
- * startService() or bindService().  The test framework provides a
- * number of alternatives for Context, including {link android.test.mock.MockContext MockContext}, 
- * {@link android.test.RenamingDelegatingContext RenamingDelegatingContext}, and 
- * {@link android.content.ContextWrapper ContextWrapper}.
+ *
+ * <p>
+ *      <strong>Dependency Injection.</strong>
+ *      A service has two inherent dependencies, its {@link android.content.Context Context} and its
+ *      associated {@link android.app.Application Application}. The ServiceTestCase framework
+ *      allows you to inject modified, mock, or isolated replacements for these dependencies, and
+ *      thus perform unit tests with controlled dependencies in an isolated environment.
+ * </p>
+ * <p>
+ *      By default, the test case is injected with a full system context and a generic
+ *      {@link android.test.mock.MockApplication MockApplication} object. You can inject
+ *      alternatives to either of these by invoking
+ *      {@link AndroidTestCase#setContext(Context) setContext()} or
