Bug

Throws an error "Cannot read property 'DataSnapshot' of undefined". https://github.com/firebase/firebase-functions-test/blob/master/src/cloudevent/generate.ts#L44

database is not exported from firebase-functions until version 3.22.0. https://github.com/firebase/firebase-functions/pull/1127/files#diff-3b2670242bbd05b6c18120f99c3e59ad0500d7c3227d3c548727f21b53b78282R43

Fix

Upgrade firebase-functions to 3.22.0 worked for me. I see it's a peerDependency, so the README just needs to be updated.

I tried opening a PR but I don't have permission.

Based on this, perhaps NOTE: This library can only be used with firebase-functions v3.20.1 or above. (in README.md) could be modified to v3.22.0.
