Cloud Firestore emulator quickstart

Let's try writing some simple tests for our security rules.

Setup

Install Node dependencies

Run npm install from this directory, and make sure that you have a recent version of the Firebase CLI tool installed (you'll need firebase --version to be at least 6.3.0).

Running the tests with the emulator

To start the firestore emulator and run the tests:

firebase emulators:exec --only firestore 'npm test'

If another app's using the port, update the firebase.json file to look like this before you run the command above.

{
  "firestore": {
    "rules": "firestore.rules"
  },
  "emulators": {
    "firestore": {
      "port": "PORT"
    }
  }
}

Either way, the command runs all the tests in the tests/ directory.

    ✓ require users to log in before creating a profile (71ms)
    ✓ should enforce the createdAt date in user profiles (79ms)
    ✓ should only let users create their own profile (57ms)
    ✓ should let anyone read any profile (40ms)
    ✓ should let anyone create a room (44ms)
    ✓ should force people to name themselves as room owner when creating a room (48ms)
