Imagine you need to test the app update process. What would you pay attention to?

When testing the application update process, it is important to check the following aspects:

• Update Compatibility: ensure that the new version installs correctly over the old one without data loss.
• Data Integrity: verify that user data is preserved and not corrupted during the update.
• Functionality: test key features of the application after the update.
• Error Handling: check how the application behaves when the update is interrupted (e.g., power loss).
• Performance: assess whether performance has degraded after the update.
• Backward Compatibility: if applicable, verify the ability to roll back to a previous version.
• Installer and Migrations: verify the correctness of the installer and database migrations.

Example: when updating a mobile application, it is important to verify that user settings and data are preserved, and that the application launches without crashes.
