Emulator Suite in Google Cloud Shell - TypeError: firebase.initializeTestApp not a function

[JollyRen]

Environment info

firebase-tools:

Platform: Windows 11 / Google Cloud Shell - Emulator Suite, CS Walkthrough

Test case

Trying to just follow the quickstart testing through Cloud Shell for rules. Getting to step 4 of 11 and it gives the error in the subject line.

"TypeError: firebase.initializeTestApp not a function"

I've looked through the node_modules folder for all the test modules and, no it isn't in the module that the script is looking through. I did see that sometime recently, in a closed issue, initializeTestApp was moved to a different module than it was in before. Perhaps this is the issue.

Steps to reproduce

Just follow the Cloud Shell tutorial explicitly

Expected behavior

The Mocha test starts and runs. Test App is initialized. The CS Walkthrough works out of the box.

Actual behavior

jollyren@cloudshell:~/rules-tutorial/quickstart-testing/cs-walkthrough/functions$ npm run test

> test
> mocha --timeout 5000 --exit

      else throw err
           ^
