Usability testing focuses on the app’s ease of use and overall user experience.

Accessibility

Screen Reader Compatibility: Test the app’s compatibility with screen readers for visually impaired users.
Text Size Adjustment: Ensure that text size can be adjusted and that the app’s layout responds appropriately.

User Feedback

Error Messages: Verify that error messages are informative and help users correct their mistakes.
Help and Support: Test the availability and functionality of help and support features within the app.

User Experience

First-Time User Experience: Assess the onboarding process for new users, ensuring it’s intuitive and informative.
Intuitive Navigation: Ensure that the app’s navigation is intuitive and user-friendly.

Security Test Cases

Security testing is essential to protect user data and maintain trust.

Data Protection

Encryption: Verify that sensitive data is encrypted both in transit and at rest.
Secure Storage: Ensure that sensitive data is stored securely on the device.

Authentication and Authorization

Multi-Factor Authentication: Test the implementation of multi-factor authentication.
Session Management: Verify that user sessions are managed securely, preventing unauthorized access.

Vulnerability Testing

SQL Injection: Test for vulnerabilities to SQL injection attacks.
Cross-Site Scripting (XSS): Verify that the app is protected against XSS attacks.
Data Breach: Assess the app’s ability to prevent data breaches and unauthorized access.

Compatibility Test Cases

Compatibility testing ensures that the app works across various devices, operating systems, and browsers.

Device Compatibility

Different Devices: Test the app on a range of devices from different manufacturers.
Operating Systems: Verify that the app works on different versions of iOS and Android.

Browser Compatibility

Mobile Browsers: Ensure that the app’s web version works on popular mobile browsers.
Cross-Browser Testing: Test the app on different browsers to ensure consistent performance and appearance.

Network Compatibility

Different Network Types: Verify that the app works on various network types (3G, 4G, 5G, Wi-Fi).
Offline Mode: Ensure that essential features are available even without network connectivity.

Localization Test Cases

Localization testing ensures that the app caters to users from different regions and languages.

Language Support

Multi-Language Support: Verify that the app supports multiple languages and that translations are accurate.
