# Development and Testing Plan

## Overview

This document outlines the development methodology and testing strategy for implementing exchange-specific helper libraries in the MEV bot project.

## Development Methodology

### Iterative Development
1. Implement core interface for each exchange
2. Add basic swap functionality
3. Implement liquidity operations
4. Add pricing functions
5. Enhance with exchange-specific features
6. Optimize performance

### Code Organization
- Separate packages for each exchange: `pkg/exchanges/uniswap`, `pkg/exchanges/sushiswap`, etc.
- Shared interfaces in `pkg/interfaces`
- Common utilities in `pkg/utils`
- Configuration in `pkg/config`

### Version Control
- Feature branches for each exchange implementation
- Regular integration with main branch
- Clear commit messages following conventional commits
- Pull request reviews for all changes

## Testing Strategy

### Unit Testing
- Test each function in isolation
- Mock external dependencies
- Test edge cases and error conditions
- Verify interface compliance
- Target >90% code coverage for core exchange functions

### Integration Testing
- Test with mainnet fork environments
- Validate against real exchange contracts
- Test multi-step operations
- Verify gas cost estimations
- Cross-platform consistency checks

### Performance Testing
- Measure execution latency
- Test throughput under load
- Benchmark gas consumption
- Profile memory usage
- Stress test with high-frequency requests

### Security Testing
- Validate input sanitization
- Test for common vulnerabilities
- Verify slippage protection
- Check for reentrancy issues
- Audit external calls

## Quality Assurance

### Code Review Process
- Required review for all pull requests
- Automated linting and formatting
- Security checks with gosec
- Documentation verification
- Test coverage verification

### Continuous Integration
- Automated testing on push/PR
- Build verification
- Security scanning
- Performance regression checks
- Code quality metrics
