Catch-all Interceptor

[schmijos]

I'm trying to setup a custom catch-all interceptor with intercept like this:

beforeEach(() => {
  cy.intercept({ url: "**" }, (req) => {
    const url = new URL(req.url);
    if (url.hostname === "localhost") {
      req.continue()
    } else {
      req.destroy()
      throw new Error(`Catch-call interceptor catched ${req.url}`);
    }
  }).as("catchAll")
});

I know about the existence of blockHosts. But I would like to guide our developers towards using stubs instead of making real requests. So just blocking with an HTTP 503 will not serve this purpose comfortably.

My current solution works so-so, because

• Whitelisted interceptions pass the interceptor but are still logged. I'd rather like to treat those requests as not intercepted at all. Maybe there's a possibility to overwrite the interceptor command, so that the catch-all interceptor is removed from any matching request?
  
• Catched interceptions log an ugly error. I bet, you could do this nicer and attach useful information to the command log. But I didn't find a solution with cy.log nor with Cypress.log which would allow me not to throw an error.
  
• Leaving away req.destroy() gives me actually a solution which is closer to the behavior I'd like because client libraries don't retry their requests. But on the other hand the requests are then not really aborted and the spinners keep spinning.
• Instead of throwing an error, I can also assert.fail. I think this is a bit closer to the issue at hand.

Does anyone have a nice solution to those problems?
