Push Notification Testing
Push notification testing verifies that notifications are triggered correctly, delivered reliably, display properly across different device states (locked, foreground, background), and that tapping one correctly deep-links to the right place in the app.
Testing needs to cover the full delivery chain, not just whether a notification was "sent": did it actually arrive, did it display with the correct content and formatting for the platform, did it respect the user's notification permission and preference settings, and does tapping it launch the app to the specific, relevant screen rather than just the app's default entry point.
Push notifications also interact with app state in ways worth testing explicitly — behavior can differ meaningfully depending on whether the app was in the foreground, backgrounded, or fully closed when the notification arrived, and each of those three states needs its own explicit test coverage.
