An intelligent web application that automatically generates comprehensive test cases for your GitHub repositories using AI. This tool streamlines the testing process by analyzing your code structure and generating relevant unit tests, integration tests, and edge case scenarios.
The AI Test Case Generator is a full-stack application that connects to your GitHub repositories, analyzes your code files, and uses artificial intelligence to generate meaningful test cases. It provides an intuitive workflow from code analysis to test generation and even automated pull request creation.
- GitHub Integration: Seamless authentication and repository access
- Intelligent File Browser: Advanced filtering, search, and file preview capabilities
- AI-Powered Analysis: Smart test case generation based on code structure and patterns
- Test Case Management: Organize, edit, and manage generated test suites
- Automated PR Creation: Generate pull requests with test files directly to your repository
- Professional UI: Modern, responsive interface with dark/light mode support

The application uses Google's Gemini AI for test generation through secure server actions. You can modify the AI service in lib/ai-actions.ts to:
- Adjust generation parameters (temperature, max tokens)
- Customize prompts for different test types
- Switch to different AI providers (OpenAI, Anthropic, etc.)
GitHub integration is handled through lib/github-api.ts. The service supports:
- Repository listing and file browsing
- File content retrieval
- Branch creation and file commits
- Pull request creation
The application implements secure practices:
- Server-side AI calls: API keys are never exposed to the client
- Secure authentication: GitHub tokens are handled securely
- Environment variables: Sensitive data is kept server-side only
- Responsive Design: Works seamlessly on desktop, tablet, and mobile
- Dark/Light Mode: Automatic theme switching based on system preference
- Modern Animations: Smooth transitions and hover effects
- Accessibility: WCAG compliant with proper ARIA labels and keyboard navigation
- Professional Typography: Clean, readable fonts optimized for developer tools
- Push your code to GitHub
- Connect your repository to Vercel
- Add environment variables in Vercel dashboard:
GEMINI_API_KEY: Your Gemini API key
- Deploy automatically on every push
The application can be deployed on any platform that supports Next.js:
- Netlify
- Railway
- DigitalOcean App Platform
- AWS Amplify
- Support for multiple programming languages
- Integration with popular testing frameworks (Jest, Mocha, Pytest)
- Code coverage analysis
- Batch processing for multiple repositories
- Team collaboration features
- Custom test templates
The AI Test Case Generator represents a significant step forward in automated testing workflows. By combining the power of artificial intelligence with intuitive user experience design, it transforms the traditionally time-consuming process of writing test cases into an efficient, intelligent workflow.
This tool not only saves developers valuable time but also ensures comprehensive test coverage by identifying edge cases and scenarios that might be overlooked in manual testing. The seamless integration with GitHub and automated PR creation makes it easy to incorporate generated tests into existing development workflows.
Whether you're working on a small personal project or managing large-scale enterprise applications, the AI Test Case Generator provides the tools and intelligence needed to maintain high-quality, well-tested codebases with minimal manual effort.
