"AssertionError: 1 accessibility violation was detected: expected 1 to equal 0"?

I encountered this same problem recently. I found that the cy.checka11y can take a violations callback and that Cyrpress will output any thrown exception.

cy.checka11y(null, null, violations => { 
  // format violations
  // manually throw violations
})

Yup, you'll want to use the callback here. Defining those tasks registers them with Cypress, but using them requires that you call them with cy.task in the callback.

There is an example that was recently added to the readme here: https://github.com/avanslaars/cypress-axe#in-your-spec-file

Seems like this is resolved with @austinezell's comment. I'm going to close this issue.

I'd strongly encourage you to reopen this, and only close it after adding a bit to the README that explains how to do this, because this is going to trip up a lot of folks who aren't in the habit of filing issues, and they won't find this information in a closed issue, because of SEO on the part of Google and friends.

Docs are the first port of call =)

There are instructions for this in the readme, right here: Using The Violation Callback

If you feel they could be improved, feel free to submit a PR
