FlakyHunter: Revolutionizing How You Detect and Fix Flaky Tests

Flaky tests are one of the silent productivity killers in software development. They cause false alarms, reduce confidence in your test suite, and waste hours of debugging time. That’s why I built FlakyHunter, a comprehensive system designed to identify, analyze, and help resolve flaky tests across any software project.

What is FlakyHunter?

FlakyHunter is a full-stack application that combines a robust backend, an interactive frontend, and extensible plugins to support multiple testing frameworks. It helps developers and QA teams:

  • Detect flaky tests in their codebase
  • Understand the root causes behind test failures
  • Track trends and patterns to improve test reliability
  • Suggest potential remediation strategies

Key Features

1. Intelligent Backend

  • Built with Python 3.13 and FastAPI for lightning-fast API responses.
  • PostgreSQL database with SQLAlchemy ORM for structured and reliable data storage.
  • Machine Learning scoring that predicts the probability of a test being flaky.
  • Root cause analysis engine to highlight why a test fails intermittently.
  • Comprehensive API endpoints to feed data into the frontend and plugins.

2. Interactive Frontend

  • Developed using React 18 with TypeScript, Vite, and Tailwind CSS.
  • Dynamic dashboards with charts, tables, and visualizations for flaky test trends.
  • Drill down into individual tests with logs, details, and root cause insights.
  • Powerful search and filtering system for test results.
  • Fully responsive, accessible, and optimized for modern development workflows.

3. Extensible Plugins

  • Pytest plugin for Python projects
  • Jest plugin for JavaScript/TypeScript projects
  • JUnit plugin for Java projects
  • Plugins automatically send test execution data to the backend for analysis.

4. CI/CD Integration

  • GitHub Actions workflow for automated testing, building, and deployment.
  • Full test coverage checks before deploying to staging or production.
  • Automatic monitoring and alerts on runtime errors.

Why FlakyHunter?

  • Saves developers countless hours debugging non-deterministic test failures.
  • Improves confidence in CI/CD pipelines.
  • Supports multiple programming languages and frameworks.
  • Provides actionable insights instead of just raw data.

How It Works

  1. Your project runs tests using a supported framework.
  2. Plugins capture the test results and send them to the FlakyHunter backend.
  3. The backend stores the data, runs ML models to predict flakiness, and performs root cause analysis.
  4. Developers access a powerful frontend dashboard to review results, trends, and suggested fixes.
  5. Continuous integration ensures your test suite is constantly monitored and optimized.

Getting Started
