I want to be able to experiment with Pairing Bot locally, which means I'll need some way to run Firestore without also running all of Google Cloud. It turns out that there's an emulator inside of gcloud which is made exactly for this purpose!

The Firestore Go SDK we're using automatically supports using this via the FIRESTORE_EMULATOR_HOST environment variable.

Changes

This sets up a single round-trip test to prove that this all works. I left space to add more because I'll be collecting them in the future as I learn about how Firestore works (and how we use it!).

I also made these tests run on PRs to the dev branch. I intend to treat them as non-blocking there, but I do think it's nice to know that we've broken unit tests before deploying, even if it's just to the test bot.

I also added a dev.sh script to help me remember how to start the emulator. It uses the same variable as the SDK so something like direnv makes it "just work".

Oh, huh, jobs run in parallel by default!

Do we need to impose an order on these? Will the emulator keep running in the background even after the job is done?

If the answer is "we need to submit this and try it to see", that's fine :D

There's already an order imposed because steps run sequentially even though their containing jobs run in parallel. (The YAML diff doesn't make this very easy to see, but I only appended to the one existing job.)

That said, I did consider splitting jobs.build and jobs.test. But go build is so fast that all it would really do is cause setup-go module-cache issues between the two jobs.
