     24  * An example of an {@link ActivityInstrumentationTestCase2} of a specific activity {@link Focus2}.
     25  * By virtue of extending {@link ActivityInstrumentationTestCase2}, the target activity is automatically
     26  * launched and finished before and after each test.  This also extends
     27  * {@link android.test.InstrumentationTestCase}, which provides
     28  * access to methods for sending events to the target activity, such as key and
     29  * touch events.  See {@link #sendKeys}.
     30  *
     31  * In general, {@link android.test.InstrumentationTestCase}s and {@link ActivityInstrumentationTestCase2}s
     32  * are heavier weight functional tests available for end to end testing of your
     33  * user interface.  When run via a {@link android.test.InstrumentationTestRunner},
     34  * the necessary {@link android.app.Instrumentation} will be injected for you to
     35  * user via {@link #getInstrumentation} in your tests.
     36  *
     37  * See {@link com.example.android.apis.AllTests} for documentation on running
     38  * all tests and individual tests in this application.
