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