When writing a test, you pass a different parameter to the object being tested instead of the real backend:. Both of these do require quite a bit of effort, and can end up giving a maintenance headache for the large complex sites. Snapshot Testing Capture snapshots of React trees or other serializable values to simplify testing and to analyze how state changes over time.
