aitestgen 0.0.2

Tool to generate simple unit test using openai api

AITestGen

Python Library to generate unit tests using OpenAI API

Installation

Create a virtual enviroment (Optional)

python -m venv venv
source venv/bin/activate # venv/Scripts/activate on Windows

Install package (require python ^3.11 version)

pip install aitestgen

Add OpenAI API Key (Required)

export OPENAI_API_KEY=<my_api_key>  # or add variable in your .env file

Example

Create a python file and add the following code:

from aitestgen.autotest import autotest

@autotest()
def sum(num1: float, num2: float) -> float:
    """This function is responsible for calculating the sum of two numbers"""
    return num1 + num2

@autotest()
def mul(num1: float, num2: float) -> float:
    """This function is responsible for calculating the multiplication of two numbers"""
    return num1 * num2

Important:

To improve results, add type annotations and documentation to the function.

Generate tests:

Run the following command (change the filename)

aitestgen generate --inputfile src/operations.py

And then you will get the following result in a .py file created in a tests folder:
