Installation Testing Notes By ShariqSP
Installation Testing in Mobile Application Testing
Installation Testing is a type of testing performed to ensure that a mobile application installs and uninstalls correctly, without errors, and behaves as expected post-installation. It verifies that the app can be installed under various conditions, handles errors gracefully, and doesn't leave residual files after uninstallation.
Why Installation Testing is Important?
- Ensures the application installs smoothly without crashing.
- Verifies proper installation under different conditions (e.g., low storage).
- Confirms that the app initializes and functions correctly after installation.
- Checks for proper uninstallation, ensuring no unnecessary files remain on the device.
Scenarios for Installation Testing
Here are some common scenarios for installation testing in mobile applications:
| Scenario | Example |
|---|---|
| Successful Installation | Verify that the app installs successfully on devices running different operating systems (e.g., Android 12, iOS 15). |
| Low Storage Space | Attempt to install the app on a device with low available storage and confirm that an appropriate error message is displayed. |
| Corrupted Installation File | Try installing the app with a corrupted APK (Android) or IPA (iOS) file and ensure the installation fails gracefully with an error prompt. |
| Installation on Different Networks | Test installing the app using Wi-Fi and mobile data to confirm the download and installation process works smoothly on both networks. |
| Uninstallation Verification | Uninstall the app and verify that no residual files or app data are left on the device. |
| Reinstallation | Install the app, uninstall it, and reinstall it to confirm there are no issues with reinstallation. |
| App Permissions | During installation, verify that the app requests the required permissions and handles user approval or denial appropriately. |
Real-World Scenario
Imagine testing the installation of a banking application like XYZ Bank Mobile App.
- Scenario 1: A user installs the app on an Android device with sufficient storage. The app should install successfully, open without errors, and display the login screen.
- Scenario 2: The same user tries to install the app on a device with low storage. The installation should fail with a message: "Not enough storage space. Please free up some space to install this application."
- Scenario 3: After uninstalling the app, the user reinstalls it. The app should install correctly and allow the user to log in without any issues.
These tests ensure that the XYZ Bank Mobile App provides a smooth experience during installation, even under different real-world conditions.
