TypeError : Cannot read properties of undefined (reading 'run')

[Harvo09]

Visiting my homepage and running checkA11y() is working just fine. My next test selects the login button to get us to the Login page. I run checkAlly() there and get the following

The documentation says this should be fine, use Cypress to interact, then call checkA11y()

// Basic usage after interacting with the page
it('Has no a11y violations after button click', () => {
// Interact with the page, then check for a11y issues
cy.get('button').click()
cy.checkA11y()
})

Any help welcome

I'm getting the same error while running my tests too !

I was seeing a similar issue, if I had a simple test it seemed to be working fine but once I started adding a few more steps everything seemed to return this same error.

I managed to fix my issue, hopefully this helps others: according to the documentation they recommended placing the cy.injectAxe(); near the top of the code block, and then in most examples I see the cy.checkA11y(); placed near the end. Well, in a few of my tests I believe I was loading a new view or page in between the two, causing it to blow up.

My fix ended up being moving all of the cy.injectAxe(); down to directly above the cy.checkA11y(); and suddenly all of my "TypeError : Cannot read properties of undefined (reading 'run')" issues disappeared.

Not sure if this is the ultimate fix, but it worked for me.
