Тестировали ли вы push-уведомления на мобильных устройствах?

Yes, testing push notifications on mobile devices is an important part of QA.

The process includes:

• Setting up a test environment with real devices or emulators.
• Sending push notifications through services (Firebase Cloud Messaging for Android, APNs for iOS).
• Checking the delivery of the notification on the device.
• Verifying the display of the notification: correctness of text, icon, sound, actions.
• Testing behavior in different app states: open, background, closed.
• Checking reactions to notification taps.
• Testing on different OS versions and devices.

Automation is possible with tools that support interaction with notifications, but often some tests are performed manually due to platform-specific features.
