Functionality
Verify that all features work as expected in a development environment. Test each feature thoroughly to ensure proper functionality across all intended use cases.
User Experience
Evaluate the overall user experience, including ease of use, navigation, and consistency in the UI/UX.
Load Testing
Conduct load testing to confirm that the extension can handle the expected volume of traffic without performance degradation. Ensure the system remains stable under peak loads.
Automated Testing
Implement automated smoke tests to quickly validate core functionality. These tests help ensure that essential features perform correctly after each code change.
Accessibility (A11y) Testing
Ensure all user-facing components are accessible in compliance with WCAG 2.1 guidelines. Use accessibility testing tools like Axe or Lighthouse, and perform manual checks with keyboard navigation and screen readers to confirm that the extension is usable by all users.
Cross-Browser and Cross-Device Testing
Test the extension across major web browsers (Chrome, Firefox, Edge) and ensure compatibility on both desktop and mobile devices, if applicable.
