Prevent/Stub network request

Current behavior:

I’ve in my application several <script>...</script> like pulling in jQuery and also a few internal things. Cypress gets errors that it is not authorised to get certain things. Now this question would be answered (if authorised or not) by an external js file. But this fails, as the “cypress user” is unknown.

Desired behavior:

A way of either overriding or mocking this <script>...</script>-tag to be able to influence the response.

• Operating System: Mac OS High Sierra
• Cypress Version: 2.0.3
• Browser Version: electron

This feature is part of part of our large rewrite of the network layer that’s actively being worked on - and you’ll be able to fully stub all network requests including ones for script tags. Read this issue: https://github.com/cypress-io/cypress/issues/687

For today - you could either blacklist these requests, or you could use some combination of document.currentScript to get access to the <script> and then swap its src attribute to something you control.

You have native access to everything in Cypress - and you can use that to alter your scripts before they are fetched.

Similar situation, I think:

I ended up blacklisting the host in my cypress.json, and then mocking it during the window:before:load event inside of a beforeEach method.

Edit: although your local scripts may not work with this solution.
