/**
 * Note: we use MoviesActivity here instead of AddonsActivity. The reason is that we use @Rule
 * to start the activity which is done prior to executing @Before. This results in a deadlock
 * situation.
 *
 * Normal startup procedure would be as follows:
 *
 * 1. Start MockTCPServer {@link AbstractTestClass#setupMockTCPServer()}
 * 2. Start activity {mActivityRule}
 * 3. Espresso waits for activity to become idle before calling {@link AbstractTestClass#setUp()}
 * 4. Add AddonsHandler {@link AbstractTestClass#setUp()}
 *
 * At step 2 the AddonsActivity displays an animated progress indicator while it waits for the
 * MockTCPServer to send the list of addons.
 * This is never send as the {@link org.xbmc.kore.testutils.tcpserver.handlers.AddonsHandler} is
 * added in {@link super#setUp()} which is never started by Espresso as it waits for
 * {@link org.xbmc.kore.ui.sections.addon.AddonsActivity} to become idle.
