Did your accessibility testing provide accurate results?

  • Including automated testing throughout development helps catch errors as you build.
  • When accessibility is part of the project from the start, the benefits increase.
  • The Digital Transformation Agency report trying to retrofit accessibility at the end of a project can cost up to 30 times the cost of incorporating accessibility progressively.

Steps to take

  1. Always combine automated testing with ongoing manual testing.
  2. Read our guide on accessibility testing.
  3. Integrate tools like axe-core, Lighthouse Audits, or AccessLint.js into your development.
  4. Use a tool like AccessLint to find accessibility issues in your GitHub pull requests.
  5. Understand the issues faced by people with slight to extreme vision problems. Use a tool like Web Disability Simulator to simulate:
    • colour blindness
    • low vision
    • Parkinsons
    • Dyslexia
    • small vocabulary
    • concentration.
