AIUnitTest 0.0.7

CLI to generate and update Python unit tests automatically using coverage and AI

AIUnitTest

AIUnitTest is a command-line tool that reads your pyproject.toml and test coverage data (.coverage) to generate and update missing Python unit tests using AI.

How it Works

1. Coverage Analysis: The tool uses coverage.py to identify lines of code that are not covered by your existing test suite.
2. Source Code Chunking: It breaks down the source code into logical chunks (functions and classes).
3. AI-Powered Test Generation: For each chunk with uncovered lines, it sends the source code and the uncovered line numbers to an AI model (like OpenAI's GPT) to generate new test cases.
4. Test File Updates: The newly generated tests are appended to the corresponding test file.

Features

• Coverage Analysis: Uses the Coverage.py API to identify untested lines.
• AI-Powered Test Generation: Calls OpenAI GPT to create or enhance test cases.
• Config-Driven: Automatically picks up coverage.run.source and pytest.ini_options.testpaths from pyproject.toml.
• Auto Mode: The --auto flag sets source and tests directories without manual arguments.
• Async & Parallel: Speeds up OpenAI requests for large codebases.

Installation

There are two ways to install AIUnitTest:

From PyPI

You can install the latest stable version from PyPI:

pip install AIUnitTest

Optional Dependencies

AIUnitTest supports optional features that can be installed as needed:

Basic Installation (OpenAI only)

pip install AIUnitTest

With HuggingFace Support

pip install AIUnitTest[huggingface]

With FAISS Indexing Support

pip install AIUnitTest[faiss]

All Optional Features

pip install AIUnitTest[all]

Development Dependencies

pip install AIUnitTest[dev]

You can also combine multiple extras:

pip install AIUnitTest[huggingface,faiss]

From GitHub (for the latest development version)

1. Clone the repository:

   git clone https://github.com/ofido/AIUnitTest.git
   cd AIUnitTest
   

2. Install the project in editable mode:

   pip install -e .
   # Or with optional dependencies:
   pip install -e .[all]
   

Usage

Automatic Mode

The easiest way to run the tool is in automatic mode. It will automatically discover your source and test folders from your pyproject.toml file.

ai-unit-test --auto

Manual Mode

You can also specify the source and test folders manually:

ai-unit-test --folders src --tests-folder tests

Generating a Test for a Specific Function

You can also generate a test for a single function:

ai-unit-test func my_module/my_file.py my_function

Indexing and Searching Tests

You can index your tests for semantic search:

ai-unit-test index

And then search for tests related to a specific query:

ai-unit-test search "my search query"

Command-Line Options

• --folders: The source code folders to analyze.
• --tests-folder: The folder where the tests are located.
• --coverage-file: The path to the .coverage file.
• --auto: Try to discover folders/tests from pyproject.toml.

Configuration

AIUnitTest uses the standard pyproject.toml file for configuration. Here are the relevant sections:

• [tool.coverage.run]:
  • source: A list of source code folders.
• [tool.pytest.ini_options]:
  • testpaths: A list of test folders.
