Modify headers and status code but not stubbing response

I have an XHR request that responds normally with a status 200 and some data. There is one case where the response is enriched with some header data. I want to simulate this case.

This is the mock setup:

cy.server().route({
  method: 'POST',
  url: /some-url/,
  headers: { key: 'value' }
});

The resulting call is a non stubbed call but also the key: value headers are missing. They are not missing when I add a stubbed response to the route config. The same happens with status.

I would agree that it would be a very useful feature. For example on our project we rely on the Cloudfront cloudfront-viewer-country header to geolocate our users so I would like to add that header when mocking the page request without modifying anything else in the response. Without it, I can’t think of any other way to test our geolocation feature.

The features requested in this issue are now possible as part of cy.route2().

cy.route2() is currently experimental and requires being enabled by passing "experimentalNetworkStubbing": true through your Cypress configuration. This will eventually be merged in as part of our standard API.

Please see the cy.route2() docs for full details: https://on.cypress.io/route2

If you encounter any issues or unexpected behavior while using cy.route2() we encourage you to open a new issue so that we can work out all the issues before public release. Thanks!
