You have this Cypress test:

cy.visit('/profile')
cy.checkA11y()

It throws an error stating axe is not defined. What is the most probable reason?

AThe <code>cy.visit()</code> command was called with an invalid URL.

BYou forgot to call <code>cy.injectAxe()</code> before <code>cy.checkA11y()</code>.

CThe <code>cy.checkA11y()</code> command requires a selector argument.

DThe axe-core library is not installed in the project dependencies.

Step-by-Step Solution

Solution:

Step 1: Understand error cause
The error indicates axe-core is not available in the page context.
Step 2: Missing injection
Without calling cy.injectAxe(), axe-core is not loaded, causing the error.
Step 3: Other options
Invalid URL or missing selector do not cause axe not defined errors; missing dependency would cause build errors, not runtime.
Final Answer:
You forgot to call cy.injectAxe() before cy.checkA11y(). -> Option B
Quick Check:
Always inject axe before checking [OK]

Quick Trick: Inject axe before checking accessibility to avoid errors [OK]
