Unable to run automated test in Shopify app in embedded mode reliably

[Rafi993]

Describe the bug

• There is no clear way to run the automated end-to-end test in the embedded Shopify app reliably.
• There is a lot of discussion about this issue in partner Slack but none of them points to a reliable solution to run automated test easily

Expected behaviour

A reliable way to mock embedded mode (and app bridge instance) so that you can run end-to-end tests in the embedded mode without having to log in to the Shopify admin

Us too, moving away from versioned npm releases completely breaks our testing setup
