Examples of Installation Testing

Installation Testing is a type of software testing that ensures software is installed, updated, and uninstalled correctly in different environments. It verifies that the process meets system requirements, handles dependencies, and leaves no residual files after uninstallation. This testing ensures a smooth, error-free setup experience for users.

Installing a Desktop Application (e.g., Microsoft Office)

Scenario: A user downloads and installs Microsoft Office on their PC.

Testing Focus:

• Verifying the installer properly installs the required components (e.g., Word, Excel, PowerPoint).
• Checking for dependencies like .NET Framework.
• Ensuring the software can handle installation interruptions and allows resumption.
• Validating proper uninstallation without leaving residual files.

Upgrading a System Application (e.g., Antivirus Software)

Scenario: A user upgrades their antivirus software from an older version.

Testing Focus:

• Testing the smooth transition from the old version to the new one.
• Checking whether existing user settings are retained.
• Ensuring the antivirus definitions update seamlessly.
• Confirming compatibility with other applications post-upgrade.

Web Application Deployment (e.g., E-commerce Website)

Scenario: An online store upgrades its platform to a new version.

Testing Focus:

• Installing the new web application on the server and ensuring database schema changes are applied correctly.
• Synchronizing the test data with live production data to avoid downtime.
• Verifying integration with payment gateways and other third-party tools.

Mobile App Installation (e.g., Social Media App)

Scenario: A user downloads and installs a social media app from Google Play or App Store.

Testing Focus:

• Ensuring the app installs correctly on different OS versions (e.g., Android 11, iOS 16).
• Verifying sufficient device storage before installation.
• Checking that the app is functional after installation and asks for appropriate permissions.
• Testing the app for quick uninstall without affecting other apps.

Enterprise Software Deployment (e.g., ERP System)

Scenario: A company deploys an ERP system like SAP across departments.

Testing Focus:

• Ensuring all modules are installed correctly (e.g., Finance, HR, Logistics).
• Validating integration with existing databases and legacy systems.
• Testing for scalability on enterprise-grade hardware.
• Confirming minimal disruption to daily operations during installation.
