What is this?

This is a minimal project that replicates the issues described in this GitHub Issue.

How to run

1. Change the project in .firebaserc to a firebase project that you own
2. Navigate to the functions folder and run npm run install
3. Open a second tab in the functions folder
4. In one tab run npm run serve to start the emulator
5. In the other tab run npm run test to run jest

If everything works correctly the test should pass and you will get a warning message from Jest saying that "Jest did not exit one second after the test run has completed."
