firestore-emulator javascript example tests 2 out of 7 fail

[moritzhabegger]

Browser: node
Browser version: v10.5.0
Operating system: macOS Mojave
Operating system version: macOS 10.14 (18A391)

What steps will reproduce the problem:

1. curl https://storage.googleapis.com/firebase-preview-drop/emulator/cloud-firestore-emulator-v1.3.0.jar -o cloud-firestore-emulator-v1.3.0.jar
2. java -jar cloud-firestore-emulator-v1.3.0.jar (or as an alternative: gcloud alpha emulators firestore start --host-port localhost:8080)
   (when I use firebase serve --only firestore with the tests i get always _ Error: Timeout of 2000ms exceeded. For async tests and hooks..._ so i downloaded the newer version of the emulator)
3. git clone https://github.com/firebase/quickstart-nodejs.git
4. cd quickstart-nodejs/firestore-emulator/javascript-quickstart/
5. npm install
6. npm test

What is the expected result?
All tests pass because it is an official get startet guide.
What happens instead of that?
Two out of seven tests fail.

Because of this issue I can't test any of my security rules.

@moritzhabegger I was not able to reproduce this, I got 7/7 passing against the latest commit of this repo.

The only difference between my setup and yours is that I used firebase serve to run the emulator. Let's dig into why you can't do that. Can you post more logs about the timeout error you're getting?

EDIT: Nevermind, scratch that, you're on the most recent version and you're using the default launcher. I cannot reproduce this behavior with those conditions.

Ah, you've run into a really devious issue with gRPC. The issue is that localhost:8080 usually binds as [::1]:8080, the ipv6 transport, but the client is preferentially trying to connect over 127.0.0.1:8080, the ipv4 transport.

This can be fixed by:

• explicitly choosing the same ipv4 or ipv6 transport on both the emulator and client (this is what firebase serve --only firestore does)
• upgrading to @firebase/testing to the latest version (gRPC fixed the underlying issue in the latest release)

[moritzhabegger]

I was able to fix the problem with following commands:

npm i -g firebase-tools
firebase setup:emulators:firestore

So it turned out, that i was using an old firebase cli version -.-, that downloaded an older firestore emulator. I also wrongly assumed, that npm i -g firebase will update the firebase cli.

For everyone who has errors like:
Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (......./test/test.js)

Try to run the two commands above.

Thank you for your time and advice!
