About pythagora
Pythagora is a JavaScript tool for generating automated tests for Node.js applications with GPT 4. It lives in the Node.js testing ecosystem and aims to create unit tests without developers writing the test code by hand. The project works by finding an exported function, collecting related functions through AST parsing, and sending that context to a server that produces the tests. The README also says the repository is deprecated and that work has moved to GPT Pilot.
