Try this evaluation

Take an API-backed workflow with a successful response, an authorization failure, and a slow dependency.

Coverage: Which user outcomes must this release prove, and which specialist checks must stay in your existing stack?
Setup: Who prepares accounts, test data, permissions and access to the deployment being tested?
Evidence: Can the engineer reproduce a reported failure from the recording and steps, without asking the tester to investigate again?
Ownership: Who updates the checks when the product changes, and can the team review what a passing result actually proves?
