Stay organized with collections Save and categorize content based on your preferences.

The Firebase Emulators make it easier to fully validate your app's behavior and verify your Firebase Security Rules configurations. Use the Firebase Emulators to run and automate unit tests in a local environment.

Install the Firebase Emulators

Before you begin make sure you have installed the Firebase CLI and configured the Firebase Local Emulator Suite

Start the emulator using the following command. The emulator runs during all your tests.

 firebase emulators:start --only firestore
 

 firebase emulators:start --only database
 

 firebase emulators:start --only storage
 

Set up tests and run the emulator

Now that you've installed the emulator, set up tests and generate reports to validate your rules' behavior before you deploy them to production.
