/**
 * Integration tests for {@link BugreportReceiver}.
 * <p>
 * These tests don't mock any component and rely on external UI components (like the notification
 * bar and activity chooser), which can make them unreliable and slow.
 * <p>
 * The general workflow is:
 * <ul>
 * <li>creates the bug report files
 * <li>generates the BUGREPORT_FINISHED intent
 * <li>emulate user actions to share the intent with a custom activity
 * <li>asserts the extras received by the custom activity
 * </ul>
 * <p>
 * <strong>NOTE</strong>: these tests only work if the device is unlocked.
