From Firebase DOCS:
Run functions locally
The Firebase CLI includes a Cloud Functions emulator which can emulate the following function types:
- HTTPS functions
- Callable functions
- Cloud Firestore functions
You can run functions locally to test them before deploying to production.
QUESTION
Is there a way to run cloud functions for Firebase Storage (ex: triggered by file upload) locally or do I need to actually deploy them for testing?

Update: the Firebase Emulator Suite now also supports Cloud Storage. This includes uploads to emulated Cloud Storage triggering emulated Cloud Functions.
See the documentation for full details.
Storage has been implemented in firebase tools 9.11.0. I just took it for a test run, and I found that functions running in the emulator are, indeed, triggered by uploads to the emulated storage.
