/**
 * This demonstrates completely isolated "unit test" of an Activity class.
 * <p>
 * This model for testing creates the entire Activity (like
 * {@link Focus2ActivityTest}) but does not attach it to the system (for
 * example, it cannot launch another Activity). It allows you to inject
 * additional behaviors via the
 * {@link android.test.ActivityUnitTestCase#setActivityContext(Context)} and
 * {@link android.test.ActivityUnitTestCase#setApplication(android.app.Application)}
 * methods. It also allows you to more carefully test your Activity's
 * performance Writing unit tests in this manner requires more care and
 * attention, but allows you to test very specific behaviors, and can also be an
 * easier way to test error conditions.
 * <p>
 * Because ActivityUnitTestCase creates the Activity under test completely
 * outside of the usual system, tests of layout and point-click UI interaction
 * are much less useful in this configuration. It's more useful here to
 * concentrate on tests that involve the underlying data model, internal
 * business logic, or exercising your Activity's life cycle.
 * <p>
 * See {@link com.kedzie.vbox.test.example.android.apis.AllTests} for
 * documentation on running all tests and individual tests in this application.
