How It Works

Effortless Test Generation

DebuggAI monitors your application as you develop, learning from real usage patterns to automatically generate comprehensive test suites.

DebuggAI automatically generating test suites

1. Run Your App

Simply run your application locally with our lightweight SDK. It works with any framework or language.

2. Automatic Monitoring

Our SDK silently monitors function calls, edge cases, and error states as you interact with your app.

3. AI Test Generation

DebuggAI analyzes the collected data and generates comprehensive test suites tailored to your codebase.

4. Seamless Integration

Tests are automatically added to your project, ready to run in your existing test framework.

Features

Comprehensive Test Coverage

DebuggAI doesn't just generate basic tests. It creates comprehensive test suites that cover edge cases, error handling, and performance scenarios.

Comprehensive Test Coverage

Automatically generate tests for edge cases, error handling, and happy paths based on real usage patterns.

Framework Agnostic

Works with any testing framework including Jest, Mocha, Pytest, JUnit, and more.

CI/CD Integration

Seamlessly integrates with your existing CI/CD pipeline to run generated tests automatically.

Real-time Test Generation

Tests are generated in real-time as you develop, ensuring your test suite grows with your codebase.

Regression Prevention

Automatically creates tests for fixed bugs to prevent regressions and ensure issues stay resolved.

Performance Testing

Identifies performance bottlenecks and generates tests to ensure your code meets performance requirements.
