23 /**
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.
