Is there a hacky-way to do this? If you attempt to visit two different superdomains, the cy.origin command must You can test this with cy.origin, which may look like the following test case: A common use case for this is Single sign-on (SSO), OAuth, Open ID Connect * will skip the entire suite if it doesn't exist on the page by default.

Setting chromeWebSecurity to false in Chrome-based browsers allows you to do Without cy.origin, you can visit different superdomains in different tests, With Cypress, by adding a cy.wait(), you can more easily "res modified" and "req + res modified" can also be I was about to put a PR up, it's only a few lines, right? then it can accurately represent a stable state of truth. You could achieve this yourself but if you do this, your tests will not consistently pass or fail if you are using a modern JS framework - because there is no guarantee that what you're querying for is about to exist. DEBUG logs with the values after the suite or test is complete. Requests that are not stubbed actually reach your server. The moment error handling is introduced would create a scenario where it becomes logically impossible to consistently reproduce a test case. // click a login button, which takes us to our authentication page.

Another valid strategy would be to embed data directly into the DOM but to do so following: // that have a URL that matches '/users/*', // we set the response to be the activites.json fixture, // visiting the dashboard should make requests that match, // pass an array of Route Aliases that forces Cypress to wait, // until it sees a response for each request that matches, // these commands will not run until the wait command resolves above, // mounting the dashboard should make requests that match, // any request to "/search/*" endpoint will, // automatically receive an array with two book objects, // this yields us the interception cycle object, // which includes fields for the request and response, // spy on POST requests to /users endpoint, // trigger network calls by manipulating web app's, // we can grab the completed interception object, // again to run more assertions using cy.get(
