MutahunterAI: Revolutionizing Software Testing with AI

MutahunterAI is an innovative, open-source tool that combines automatic test generation with advanced LLM-based mutation testing. This powerful solution is designed to enhance software quality across various programming languages, making it an invaluable asset for developers and QA teams alike.

Key Features

Language Agnostic Approach

MutahunterAI supports any language that provides coverage reports in Cobertura XML, Jacoco XML, and lcov formats. This versatility allows seamless integration into diverse development environments.

Automatic Unit Test Generation

Leveraging Large Language Models (LLMs), MutahunterAI identifies gaps in test coverage and automatically generates unit tests to increase both line and mutation coverage. This feature ensures comprehensive testing without manual intervention.

LLM Context-aware Mutations

Utilizing state-of-the-art LLM models, MutahunterAI creates context-aware mutants that are more effective in detecting potential faults. These AI-generated mutants have:

• Higher fault detection potential
• Fewer equivalent mutants
• Greater coupling and semantic similarity to real faults

Diff-Based Mutation Testing

MutahunterAI optimizes the testing process by focusing on modified files and lines based on the latest commit or pull request changes. This targeted approach ensures efficient use of resources and faster feedback cycles.

LLM Surviving Mutants Analysis

The tool automatically analyzes survived mutants, providing valuable insights into potential weaknesses in the test suite and identifying areas for improvement in the codebase.

Benefits for Developers

1. Improved Code Quality: By generating comprehensive tests and intelligent mutants, MutahunterAI helps identify and fix potential bugs early in the development cycle.

2. Time Efficiency: Automatic test generation and targeted mutation testing save developers countless hours that would otherwise be spent on manual test creation and execution.

3. Continuous Integration Ready: Easily integrate MutahunterAI into your CI/CD pipeline for consistent, automated testing with each code change.

4. Flexibility: Support for various LLM providers, including self-hosted options, Anthropic, OpenAI, and others via LiteLLM, allows teams to choose the best fit for their needs and resources.

Getting Started

MutahunterAI offers a quick start option through Replit, making it easy for developers to experiment with the tool. For more detailed setup and usage instructions, refer to the project's GitHub repository.
