This repository contains the backend system for A/B testing built on Firebase Cloud Functions and Firebase Realtime Database. The system enables the execution of multiple concurrent experiments, facilitates event tracking for user entry and exit from tests, and supports sophisticated conditions for user segmentation.

• Multiple Concurrent Experiments: Conduct multiple A/B tests simultaneously.
• User Segmentation: Configure advanced conditions for precise user segmentation.
• Consistent User Assignment: Ensure consistent user assignment to AB-groups throughout the experiment duration.
• Robust Configuration Management: Manage A/B test configurations effectively, specifying parameters like test duration, variant proportions, and experimental conditions.
• Pause, Resume, and Stop: Control the experiment lifecycle with the ability to pause, resume, and stop tests at any time.

1. Clone the repository:

   git clone https://github.com/yanmasharski/tuna-ab.git
   cd tuna-ab

2. Set up Firebase project:

   • Create a Firebase project on the Firebase Console.
   • Configure Firebase credentials and update .firebaserc.

3. Install dependencies:

   cd functions
   npm install

4. Deploy Cloud Functions:

   firebase deploy --only functions

5. Set up Realtime Database rules:

   • Configure database rules according to your experiment requirements.

• Define experiments, conditions, and parameters in the Realtime Database.
• Use provided API endpoints for controlling experiments.

1. Start an Experiment:

   • Endpoint: /startExperiment
   • Method: POST
   • Payload: { experimentId, conditions, duration, variants }

2. Pause/Resume/Stop an Experiment:

   • Endpoint: /controlExperiment
   • Method: POST
   • Payload: { experimentId, action } (actions: "pause", "resume", "stop")

3. Get Experiment Results:

   • Endpoint: /getExperimentResults
   • Method: GET
   • Parameters: experimentId

Update the Realtime Database with experiment configurations:

{
  "experiments": {
    "experimentId": {
      "conditions": {
        "segment": "conditionA"
      },
      "duration": 7, // in days
      "variants": {
        "control": 0.5,
        "variantA": 0.25,
        "variantB": 0.25
      }
    }
  }
}

Feel free to explore additional features and customize the system as needed. Happy testing!
