[🚀 Request] Running E2E tests that rely on mocking certain logic

[SumayyaZiyad]

Hi all,
I am in need of running E2E tests for an extension. However this extension depends on several external calls that are made when interacting with the UI (eg: Certain UIs are only loaded if the user is logged in and the login is handled via external calls). Unfortunately, these calls cannot be made in the test environment and they need to be mocked for testing purposes. Is there a way that we can integrate the concept of mocking in the same test environment so that we can test the UI from end to end.
