What Measures Are Involved in Cross-Browser Testing?
Compatibility testing includes everything, but you may not always have the time for that. To do it right, product teams constrain their testing with a test specification document (test specs) which outlines broad essentials—a list of features to test, what browsers/versions/ platforms to test on in order to meet the compatibility benchmark, test scenarios, timelines, and budget.You can categorise the features that will undergo testing like this:
- Base Functionality: To ensure that basic functionality works on most browser-OS combinations. For example, you could be testing to verify that:
- All dialogs boxes and menus are working as intended
- All form fields accept inputs after validating them correctly
- Website handles first-party cookies (and features like personalisation that are dependent on them) correctly seamless touch input for mobiles or tablets.
- Design: This ensures that the website’s appearance—fonts, images, and layout—matches the specifications shared by the Design team.
- Accessibility: Accounts for compliance with Web Content Accessibility Guidelines (WCAG) to enable differently-abled users to access the website.
- Responsiveness: Verifies that design is fluid and fits different screen sizes/orientations.
