/**
 * This class provides functional testing of a single activity.  The activity under test will
 * be created using the system infrastructure (by calling InstrumentationTestCase.launchActivity())
 * and you will then be able to manipulate your Activity directly.  Most of the work is handled
 * automatically here by {@link #setUp} and {@link #tearDown}.
 * 
 * <p>If you prefer an isolated unit test, see {@link android.test.ActivityUnitTestCase}.
 * 
 * @deprecated new tests should be written using 
 * {@link android.test.ActivityInstrumentationTestCase2}, which provides more options for
 * configuring the Activity under test
