By tianshanghong. Category: Unit test generation. Homepage
The GPT4Go README describes it as an open-source Go command-line tool that generates unit test files for Go code using OpenAI's ChatGPT. It walks a directory or file and writes tests into _test.go files for functions that lack coverage. It runs locally with the user's own OpenAI API key, and gpt-3.5-turbo is the default model. The project is MIT licensed. The repository is public and not archived, but its last commit is dated 5 April 2023.
