GPT4Go: AI-Powered Test Case Generation for Golang πŸ§ͺ

English | δΈ­ζ–‡

GPT4Go is an open-source project that auto-generates test case files for Golang using OpenAI's ChatGPT 🌐 . The project helps developers quickly create test cases for their functions, ensuring that their code is tested efficiently and comprehensively πŸ§ͺ .

🌟 Features

  • 🎯 Auto-generates test cases for Golang functions using OpenAI's ChatGPT.
  • 🚫 Skips generating test cases for already tested functions.
  • πŸ’‘ Provides suggestions for breaking down large functions for better software engineering practices.
  • πŸ“š Generates well-organized, easy-to-read test case code.

πŸ›  Installation

  1. Ensure that you have Golang installed on your system πŸ’» . If not, please follow the official installation guide.

  2. Clone the repository πŸ“¦ :

git clone
  1. Change into the project directory πŸ“‚ :
cd GPT4Go
  1. Build the project πŸ”¨ :
go build .
  1. Set the required environment variables 🌍 :
export OPENAI_API_KEY=your_openai_api_key
export GPT_MODEL=model_name  # (optional, defaults to gpt-3.5-turbo)

From the OpenAI website, you can obtain an API key for OpenAI πŸ”‘ . You can also specify the model you want to use for generating test cases. The default model is gpt-3.5-turbo, which is the fastest model available 🏎 , while gpt-4 is the most accurate model 🎯 . You can find a list of all available models here.

πŸ“š Usage

To generate test cases for a specific directory or file, run the following command:

./GPT4Go path/to/your/target/directory/or/file

This command will walk through the specified directory or file and generate test cases for all functions that do not have corresponding test cases in the _test.go file.

Please note that you will need an API key for OpenAI to use the ChatGPT functionality πŸ” . You can obtain one from OpenAI's website.
