Overview

Integrating Firebase Authentication with Locust can enhance your load testing by simulating real-world user authentication scenarios.

Setup

1. Set Up Firebase Authentication:

• Create a Firebase Project: If you haven't already, create a project in the Firebase Console.

• Enable Authentication Methods: Navigate to the "Authentication" section and enable the desired sign-in methods, such as Email/Password, Google, or others.

2. Obtain Firebase Authentication Tokens:

To authenticate users during load testing, you'll need to generate Firebase Authentication tokens. This can be achieved using Firebase's REST API:

• Email/Password Authentication:

  Send a POST request to Firebase's identity toolkit endpoint with the user's email and password to receive an ID token. Detailed instructions are available in the Firebase Authentication REST API guide.

• Custom Authentication Systems:

  If you're using a custom authentication system, you can integrate it with Firebase Authentication to generate tokens. This process is outlined in the Firebase Authentication documentation.

3. Integrate Firebase Authentication with Locust:

Once you have the ID tokens, you can incorporate them into your Locust tests:

• Include the ID Token in Requests:

  In your Locust tasks, add the Authorization header with the ID token for each request:

  from locust import HttpUser, task
  
  class FirebaseUser(HttpUser):
      def on_start(self):
          # Obtain the Firebase ID token
          self.id_token = "YOUR_FIREBASE_ID_TOKEN"
  
      @task
      def authenticated_request(self):
          headers = {
              "Authorization": f"Bearer {self.id_token}"
          }
          self.client.get("/your/protected/endpoint", headers=headers)
  

• Automate Token Retrieval (Optional):

  For dynamic token generation, implement a method to obtain the ID token programmatically within the on_start method. This ensures each simulated user has a unique token.
