Introduction

momentum analyses your codebase and understands intended code behavior and tests it at every git push to ensure the code is ready for production. It generates visualisation and precise context for test plans and test cases for all entry points detected in the system.

What is a behavior?

A behavior is defined as a task or functionality you were trying to create using your code. Examples could be deleting a document using a deleting API or creating a new user in the database. Behaviors can also be more complex sometimes where third-party dependencies are associated for example fetching data from a payment API to check the status. Behaviours must be independently executable tasks.

Here's how momentum can help you!

• Blast Radius: This will be a list of endpoints that could potentially be affected by the changes you made in your code. This will also be a starting point to decide what parts of your code need to be tested before shipping to production..

• Dependency Visualization: Visualize code dependencies and relationships.

• Behaviour identification: Automatically identify behaviors written in your code and generate a plan to test their functionality

• Code generation to test functionality: Generate code to test all behaviors identified and run it in your local environment through momentum

  

• Run code in local dev environment: No need for yet another yaml, our cli works with your existing dev environment to run code.

  

• Debug code: Based on the stacktrace of the run, momentum can diagnose and propose a solution

Installation

To get started with Momentum, follow these steps:

Steps

1. Clone the repository:

   git clone https://github.com/getmomentum/momentum-core.git
   cd momentum-core

2. Set up the virtual environment:

   python -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt

3. Setup keys and .env: You will have to setup keys for services like firebase auth, github app, Open AI, portkey among others. Follow the detailed instructions here

4. Start the application:

   ./start_momentum.sh

Note: You might need to make it an executable, do it by running chmod +x start_momentum.sh
