Web testing checklist
Perform the following web testing checks to ensure your web page is accessible.
Overview
Both automated and manual testing should be performed to verify the accessibility of a web page. Automated testing can generally help to catch 25 – 30% of errors, but alone it cannot confirm WCAG conformance. Automated tools only test for limited subset of accessibility requirements. A website can receive a high accessibility score with automated testing tools, but still have issues that can prevent someone from using the site.
If you are a Commonwealth employee, complete this checklist before requesting an accessibility review.
Automated testing tools such as Deque's axe DevTools, the Web Accessibility Evaluation tool (WAVE) from WebAIM, and Accessibility Insights from Microsoft will provide a report of issues found on the page. Other tools like the Accessible Name and Description Inspector (ANDI) from SSA.gov help you inspect individual page elements and shows you what information assistive technology is receiving from that element.
Screen reader testing qualifications
Screen reader testing is always needed for web pages. However, due to the steep learning curve with screen reader tools, we only recommend testing with a screen reader if you have extensive experience doing so.
It is only recommended to test with a screen reader if you are:
- An Accessibility subject matter expert, or
- A tester with at least one year of screen reader testing experience, or
- A daily native screen reader user
