Realtime Database 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 7.0.0).

Running the tests with the emulator

To start the database emulator and run the tests:

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

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

{
  "database": {
    "rules": "database.rules.json"
  },
  "emulators": {
    "database": {
      "port": "PORT"
    }
  }
}

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