WCAG success criteria that can't be autmatically tested

There are many accessibility audit tools out there. The most mainstream one is probably Chrome's Lighthouse Accessibility audit. But let me tell you a secret.

Accessibility testing isn't done after achieving a green Lighthouse score.

Here's Steve Faulkner listing WCAG success criteria that aren't covered by today's tools.

Some obvious examples:

Automated tools can detect missing alt attributes but cannot determine if alternative text is meaningful.

Tools can check for semantic HTML elements (e.g., headings, lists, tables) but cannot determine if relationships are accurately conveyed.

Tools can analyze DOM order, but manual review is needed to verify if reading order makes sense.

Tools can verify the presence and structure of the title element, but cannot determine whether the title text is meaningful or descriptive.

Tools can detect link text, but manual testing is needed to verify if the link text makes sense in context.

Tools are great for "obvious" technical accessibility but for everything else manual testing is still required.
