I suggest you check out the documentation on TypeScript to get yourself up and running. message that looks like this: This gives you the best of both worlds - a fast error feedback loop when cy.wait('@file'); It seems that requests are taking more than Cypress's defaults for such a thing. However, using window context might help when you try to collect data from your whole spec and then use it in after() hook. With this solution it will make dynamic stubbing in larger applications more manageable and help to take away logic handling from the tests themselves. Does that make sense? With passing these arguments into cy.intercept, it ensures that only the API call with a POST method is intercepted and its URL has to contain the string given as a substring.
