testing support for concurrent HTTP calls and Firestore side effects in Firebase Cloud Functions (Python, Gen 2)

What I’m looking for

* A Python testing approach or library that can help for generation 2 functions & firebase.
* Mock/simulate multiple concurrent POST requests.
* Assert Firestore database state after execution.
* Something that works well the firebase local emulator.

What I have tried so far

1. I have found testing documentation for js : https://firebase.google.com/docs/functions/unit-testing
2. Tried testing on firebase emulator with little success since concurrency behaviour greatly differs from production:https://cloud.google.com/firestore/native/docs/emulator#transactions
3. Unit test samples only involve js : https://github.com/firebase/functions-samples/tree/main?tab=readme-ov-file

Start by comparing the Firebase JavaScript unit-testing documentation with the requested Python Gen 2 workflow, then review the linked Firestore emulator concurrency guidance. The issue is complete only when a reproducible approach covers concurrent POST requests, Firestore state assertions, and Firebase Local Emulator use.
