Comparativa de tres herramientas de evaluación de la accesibilidad web

En Comparing 3 Top Automated Accessibility Testing Tools: WAVE,, and Google Lighthouse, se comparan tres herramientas de evaluación automática de la accesibilidad web. La conclusión es:

The advantages and limitations of automated tools: a few examples

Automated Tools Will Suffice for the following:

  • Does the image have alt text?
  • Does the form field have a label and description?
  • Does the content have headings?
  • Is the HTML valid?
  • Does the application UI follow WCAG guideline X?

Human Intervention Is Required for the following:

  • Is the alt text accurate given the context?
  • Is the description easy to understand?
  • Do the headings represent the correct hierarchy?
  • Is the HTML semantic?
  • Does the application UI behave as expected?

While automated tools can discover many critical issues, there are even more issues that need human analysis. If there is a vague or misleading alt tag, that is just as bad from a usability standpoint as a missing alt tag, and an automated tool won’t catch it. You need someone to go through the site with a sharp and trained eye.

In the end, to fully test for accessibility issues, a combination of automated and manual testing is required. Automated testing tools provide a good starting point for testing, point to patterns of errors that humans can then look out for, and can catch issues before they go to production.
