Cómo automatizar las pruebas de accesibilidad

En el artículo Automating Your Accessibility Tests se explica un método para automatizar las pruebas de accesibilidad:
Accessibility is one of those things we all wish we were better at. It can lead to a bunch of questions like: how do we make our site better? How do we test what we have done? Should we spend time each day going through our site to check everything by hand? Or just hope that everyone on our team has remembered to check their changes are accessible?
This is where automated accessibility tests can come in. We can set up automated tests and have them run whenever someone makes a pull request, and even alongside end-to-end tests, too.
Automated tests can’t cover everything however; only 20 to 50% of accessibility issues can be detected automatically. For example, we can’t yet automate the comparison of an alt attribute with an image’s content, and there are some screen reader tests that need to be carried out by hand too. To ensure our site is as accessible as possible, we will still need to carry out manual tests, and I will cover these later.
