## What it is
Pythagora is an npm CLI tool (with a VS Code extension) that uses LLMs like GPT-4 to automatically generate unit and integration tests for Node.js applications without developers writing test code. The repository is now deprecated in favor of the successor project GPT Pilot.

## Use cases
- generate unit tests for a nodejs function automatically
- create integration tests by recording server activity
- increase test coverage of an existing javascript codebase
- find bugs in node.js code with generated tests
- generate api tests for express apps without writing code

## When to choose
- you maintain a legacy Node.js/Express/MERN app with little or no test coverage
- you want LLM-generated unit or integration tests from a single command
- you want to record real server traffic to build integration tests

## When to avoid
- you need an actively maintained tool - this repo is deprecated in favor of GPT Pilot
- your codebase is not Node.js/JavaScript
- you cannot send proprietary code to external LLM APIs
- you need deterministic tests without LLM API costs
