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