Waiting arbitrary time for the checks to work

See original GitHub issue

Related: #22, vercel/next.js#7945

Full repo: here (note: some of the packages there are not yet published, but the test can run without them)

I have a simple test:

import formatAxeLog from "../helpers/formatAxeLog";

describe("Home page", () => {
  beforeEach(() => {
    cy.visit("/");
  });
  it("Has no detectable a11y violations on load", () => {
    cy.injectAxe();
    // cy.wait(500);
    cy.checkA11y(null, null, formatAxeLog);
  });
});

When I run the tests multiple times they sometimes fail (due to vercel/next.js#7945, as they should), sometimes pass. The only “reliable” way is just to wait. Am I doing something wrong, or this is a bug?

Can we make it wait the same timeout amount that cypress waits for before failing an assertion?

I’m having the same issue with an Angular app <a href="somwhere">{{ 'some.text' | translate }}</a> translations are fetched so they sometimes take a bit longer to appear

Any possible solutions without cy.wait(1000); ? I want to avoid that workaround.

Instead of wait, you can try and get a DOM element that you know will render once the page is ready for the tests to run.

Given a markup like

<html>
  ...
  <body>
    <main data-test="main-region">
      This loads when the page is ready for testing.
    </main>
  </body>
</html>

you could write a test like this

it('has no detectable a11y violations on load', () => {
  cy.visit('/')
  cy.get('[data-test=main-region]')
  cy.injectAxe()
  cy.checkA11y()
})
