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

Commencez par comparer la documentation de Firebase sur les tests unitaires JavaScript avec le workflow Python Gen 2 demandé, puis examinez les indications liées concernant la concurrence de l’émulateur Firestore. L’issue n’est complète que lorsqu’une approche reproductible couvre les requêtes POST concurrentes, les assertions sur l’état de Firestore et l’utilisation de Firebase Local Emulator.
