Fail tests that have unexpected API requests

Is this a Feature or Bug?

Feature

Desired behavior:

I’d like a way to fail a test for any XHR calls that are not expected (ie. that no cy.route() has been set for). Current there’s a force404, but that’s not enough to be able to actually cause a test to fail

I had thought of using the onResponse option but it gets bypassed for the requests that force404 handles.

cy.server({
  force404: true,
  onResponse: xhr => {
    if (xhr.status === 404) {
      expect(true).to.equal(false);
    }
  }
});

Any news about this, I’d love to see this happen. Is there a lot of work ? I can work on if not

So, am I missing something, or is there actually no way to check that no request during the test returned with 500 status code? If my backend responds with 500, then there’s definitely an issue that I’d like to fix, so I want the test to fail.
