Myth: Automatic tests are enough for accessibility

There is an all-in-one article including every part from this series (if you want prefer to read it all at once instead of "by installments")

Automated testing for accessibility is possible and highly recommended. But it is not a replacement for manual testing: automatic tests only detect ~30% of the issues.

Even if we can simulate a user's behavior with the keyboard and tab, check for color contrast, or a specific HTML structure, there are still tests that we cannot automate and behaviors that we cannot simulate. Thus, limiting the capacity of what automated tests can do.

This is not to say that we should drop automatic accessibility tests. On the contrary, we should embrace them and use them in all our projects. It is important to remember that they complement and not replace good old manual testing.
