AI Test Craft

Automated Unit Test Generation for Python

AITestCraft is a Python package that assists developers in generating unit tests for their code. It leverages OpenAI's GPT models to create test cases based on the structure and requirements of your codebase.

Features:

• Automated generation of unit tests from JSON configuration.
• Support for Python 3.10 and other versions.
• Allows for additional comments to guide test case creation.
• Sequential file processing for context-aware test generation.

Prerequisites:

To use AITestCraft, you need an OpenAI API key. To obtain it, follow these steps:

1. Sign up for an account at OpenAI.
2. Navigate to the API section and follow the instructions to generate your API key.

Before running AITestCraft, ensure that your OPENAI_API_KEY environment variable is set with your OpenAI API key. Alternatively, you can specify a custom environment variable name for your OpenAI API key using the command-line interface.

Installation:

Install AITestCraft using pip:

pip install aitestcraft

Usage:

First, set the OPENAI_API_KEY environment variable or a custom one:

For Unix-based systems (Linux/Mac):

export OPENAI_API_KEY='your_api_key_here'

For Windows:

set OPENAI_API_KEY=your_api_key_here

Alternatively, use a custom environment variable:

export MY_ENV_VAR_NAME='your_api_key_here'

To generate unit tests, create a JSON configuration file named to-test.json:

{
  "language": "python",
  "language_version": "3.11",
  "model": "gpt-3.5-turbo",
  "overwrite": "never",
  "additional_comments": [
    "Use functions for each testcase and not unittest.TestCase"
  ],
  "files": [
    {
      "code": "aitestcraft/conf_representation.py",
      "test": "tests/test_conf_representation.py"
    },
    {
      "code": "aitestcraft/validators.py",
      "test": "tests/test_validators.py"
    },
    {
      "code": "aitestcraft/ai_generator.py",
      "test": "tests/test_ai_generator.py"
    }
  ]
}

Then run the package with:

aitestcraft to-test.json

Or if you're using a custom environment variable for the API key:

python aitestgen.py --open-ai-env-var MY_ENV_VAR_NAME ./to-test.json

Configuration Fields:

• language: Programming language used.
• language_version: Version of the programming language.
• model: OpenAI model used for generating tests.
• overwrite: ["neve" / "always"] If set to "never", existing test files will not be overwritten.
• additional_comments: Optional, global comments for test generation.
• files: A list of objects representing the source code and the test files.

In the files, if a comment starts with AI-TEST, it indicates a message for the AI to include specific demands for the next line, like so:

# AI-TEST: don't test this condition

Note:

The generated tests may require minor adjustments to fit the exact needs of your project.

Order the files in to-test.json from the most standalone files to those with the most dependencies. This helps to provide context that can improve the quality of the generated tests.

Disclaimer:

The test generation is not guaranteed to be perfect and might need adjustments to work seamlessly with your codebase.
