TestPilot
By GitHub Next. Category: Unit test generation. Homepage
The GitHub Next repository README describes TestPilot as a tool that generates unit tests for npm packages written in JavaScript or TypeScript using a large language model. It is installed from source and requires the user's own LLM completion endpoint. Generated tests use the Mocha framework. The code is published under the MIT licence. The README calls it an early exploration made available for research. GitHub Next archived the repository on 3 February 2025, making it read-only, and the README points to TestPilot 2 in the neu-se/testpilot2 repository as the newer version.
