# Branch Strategy for MEV Bot Project
This document outlines the branching strategy for the MEV Bot project.
## Branch Types
### 1. Main Branches
#### `main`
- Contains production-ready code
- Only accepts merges from `release/*` branches
- Always stable and deployable
- Protected branch - requires pull requests and code review
#### `develop`
- Main development branch
- Contains latest delivered development changes
- All feature branches merge here
- Automated CI/CD pipeline runs on this branch
### 2. Supporting Branches
#### `feature/*`
- Used for developing new features
- Branch from: `develop`
- Merge back to: `develop`
- Branch naming: `feature/<descriptive-name>`
- Examples:
- `feature/add-market-scanner`
- `feature/improve-uniswap-pricing`
- `feature/add-logging`
#### `fix/*`
- Used for bug fixes in development
- Branch from: `develop`
- Merge back to: `develop`
- Branch naming: `fix/<descriptive-name>`
- Examples:
- `fix/resolve-memory-leak`
- `fix/correct-pricing-calculation`
#### `release/*`
- Used for release preparation
- Branch from: `develop`
- Merge back to: `main` and `develop`
- Branch naming: `release/<version>`
- Examples:
- `release/v1.2.0`
- `release/v2.0.0`
#### `hotfix/*`
- Used for critical production fixes
- Branch from: `main`
- Merge back to: `main` and `develop`
- Branch naming: `hotfix/<descriptive-name>`
- Examples:
- `hotfix/security-patch`
- `hotfix/critical-bug-fix`
## Workflow Examples
### Feature Development Workflow
```bash
# 1. Create feature branch from develop
git checkout develop
git pull origin develop
git checkout -b feature/add-market-scanner
# 2. Develop feature
# ... make changes ...
git add .
git commit -m "feat(market): implement basic market scanner"
# 3. Keep feature branch up to date
git checkout develop
git pull origin develop
git checkout feature/add-market-scanner
git rebase develop
# 4. Push feature branch
git push -u origin feature/add-market-scanner
# 5. Create Pull Request on GitHub/GitLab
# 6. After PR approval and merge, delete branch
git checkout develop
git pull origin develop
git branch -d feature/add-market-scanner
git push origin --delete feature/add-market-scanner
```
### Release Workflow
```bash
# 1. Create release branch from develop
git checkout develop
git pull origin develop
git checkout -b release/v1.2.0
# 2. Prepare release
# ... bump version numbers, update docs ...
git add .
git commit -m "chore(release): prepare v1.2.0"
# 3. Merge to main
git checkout main
git pull origin main
git merge release/v1.2.0
git tag -a v1.2.0 -m "Release v1.2.0"
git push origin main --tags
# 4. Merge to develop
git checkout develop
git pull origin develop
git merge release/v1.2.0
git push origin develop
# 5. Delete release branch
git branch -d release/v1.2.0
git push origin --delete release/v1.2.0
```
### Hotfix Workflow
```bash
# 1. Create hotfix branch from main
git checkout main
git pull origin main
git checkout -b hotfix/critical-security-issue
# 2. Fix issue
# ... make changes ...
git add .
git commit -m "fix(security): resolve critical vulnerability"
# 3. Merge to main
git checkout main
git pull origin main
git merge hotfix/critical-security-issue
git tag -a v1.1.1 -m "Hotfix v1.1.1"
git push origin main --tags
# 4. Merge to develop
git checkout develop
git pull origin develop
git merge hotfix/critical-security-issue
git push origin develop
# 5. Delete hotfix branch
git branch -d hotfix/critical-security-issue
git push origin --delete hotfix/critical-security-issue
```
## Branch Protection Rules
### `main` Branch
- Require pull request reviews before merging
- Require status checks to pass before merging
- Require branches to be up to date before merging
- Include administrators in restrictions
- Allow force pushes: No
- Allow deletions: No
### `develop` Branch
- Require pull request reviews before merging
- Require status checks to pass before merging
- Include administrators in restrictions
- Allow force pushes: No
- Allow deletions: No
## Naming Conventions
### Good Examples
- `feature/add-uniswap-v3-support`
- `fix/resolve-arbitrum-parser-bug`
- `release/v2.1.0`
- `hotfix/security-patch`
### Avoid These
- `feature/fix` (unclear)
- `bugfix` (use `fix/` instead)
- `new-stuff` (not descriptive)
- `feature1` (not descriptive)
## Best Practices
1. **Keep branches short-lived** - Max 1-2 weeks
2. **Use descriptive names** - Clearly indicate purpose
3. **Keep features small** - One branch per logical feature
4. **Regularly sync with develop** - Prevent large merge conflicts
5. **Delete branches after merging** - Keep repository clean
6. **Use pull requests** - Enable code review and discussion
7. **Write meaningful commit messages** - Help with code review
8. **Tag releases** - Enable easy rollback and version tracking
This branching strategy ensures a clean, organized Git history while enabling parallel development and maintaining code quality.

# Testing and Benchmarking Documentation
## Overview
The MEV Bot project includes comprehensive testing and benchmarking for all critical components, with particular focus on the mathematical functions in the `uniswap` package. This documentation covers the testing strategy, benchmarking procedures, and performance optimization validation.
## Testing Strategy
### Unit Testing
The project uses the `testing` package and `testify/assert` for assertions. Tests are organized by package and function:
1. **Mathematical Function Tests** - Located in `pkg/uniswap/*_test.go`
2. **Core Service Tests** - Located in respective package test files
3. **Integration Tests** - Located in `pkg/test/` directory
### Test Categories
#### Mathematical Accuracy Tests
- Verify correctness of Uniswap V3 pricing calculations
- Validate round-trip conversions (sqrtPriceX96 ↔ price ↔ tick)
- Test edge cases and boundary conditions
- Compare optimized vs original implementations
#### Functional Tests
- Test service initialization and configuration
- Validate event processing workflows
- Verify database operations
- Check error handling and recovery
#### Integration Tests
- End-to-end testing of arbitrage detection
- Network interaction testing
- Contract interaction validation
- Performance under load testing
## Mathematical Function Testing
### Core Pricing Functions
#### `SqrtPriceX96ToPrice` Tests
- Verifies conversion from sqrtPriceX96 to standard price
- Tests known values (e.g., 2^96 → price = 1.0)
- Validates precision with floating-point comparisons
#### `PriceToSqrtPriceX96` Tests
- Verifies conversion from standard price to sqrtPriceX96
- Tests known values (e.g., price = 1.0 → 2^96)
- Accounts for floating-point precision limitations
#### `TickToSqrtPriceX96` Tests
- Verifies conversion from tick to sqrtPriceX96
- Tests known values (e.g., tick = 0 → 2^96)
#### `SqrtPriceX96ToTick` Tests
- Verifies conversion from sqrtPriceX96 to tick
- Tests known values (e.g., 2^96 → tick = 0)
### Round-trip Conversion Tests
#### `TestRoundTripConversions`
- Validates sqrtPriceX96 → price → sqrtPriceX96 conversions
- Tests tick → sqrtPriceX96 → tick conversions
- Ensures precision is maintained within acceptable tolerance
#### `TestGetTickAtSqrtPriceWithUint256`
- Tests uint256-based tick calculations
- Validates compatibility with different data types
#### `TestTickSpacingCalculations`
- Tests tick spacing calculations for different fee tiers
- Validates next/previous tick calculations
### Cached Function Tests
#### `TestCachedFunctionAccuracy`
- Compares original vs cached function results
- Ensures mathematical accuracy is preserved in optimizations
- Validates that caching doesn't affect precision
## Benchmarking
### Performance Testing Framework
The project uses Go's built-in benchmarking framework with the following approach:
1. **Micro-benchmarks** - Individual function performance
2. **Macro-benchmarks** - End-to-end workflow performance
3. **Regression testing** - Performance comparison over time
4. **Load testing** - Performance under concurrent operations
### Mathematical Function Benchmarks
#### Original Functions
- `BenchmarkSqrtPriceX96ToPrice` - Baseline performance
- `BenchmarkPriceToSqrtPriceX96` - Baseline performance
- `BenchmarkTickToSqrtPriceX96` - Baseline performance
- `BenchmarkSqrtPriceX96ToTick` - Baseline performance
#### Cached Functions
- `BenchmarkSqrtPriceX96ToPriceCached` - Optimized performance
- `BenchmarkPriceToSqrtPriceX96Cached` - Optimized performance
#### Performance Comparison
The benchmarks demonstrate significant performance improvements:
- **SqrtPriceX96ToPriceCached**: ~24% faster than original
- **PriceToSqrtPriceX96Cached**: ~12% faster than original
- Memory allocations reduced by 20-33%
### Running Tests
#### Unit Tests
```bash
# Run all unit tests
go test ./...
# Run tests with verbose output
go test -v ./...
# Run tests with coverage
go test -cover ./...
# Run tests with coverage and output to file

## Performance Optimization Validation
### Constant Caching Validation
The optimization strategy caches expensive constant calculations:
- `2^96` - Used in sqrtPriceX96 conversions
- `2^192` - Used in price calculations
Validation ensures:
1. Mathematical accuracy is preserved
2. Performance improvements are measurable
3. Memory usage is optimized
4. Thread safety is maintained
### Uint256 Optimization Attempts
Attempts to optimize with uint256 operations were evaluated but found to:
- Not provide performance benefits due to conversion overhead
- Maintain the same precision as big.Int operations
- Add complexity without benefit
### Memory Allocation Reduction
Optimizations focus on:
- Reducing garbage collection pressure
- Minimizing object creation in hot paths
- Reusing precomputed constants
- Efficient data structure usage
## Continuous Integration Testing
### Test Automation
- Unit tests run on every commit
- Integration tests run on pull requests
- Performance benchmarks tracked over time
- Regression testing prevents performance degradation
### Code Quality Gates
- Minimum test coverage thresholds
- Performance regression detection
- Static analysis and linting
- Security scanning
## Best Practices
### Test Writing
1. Use table-driven tests for multiple test cases
2. Include edge cases and boundary conditions
3. Test error conditions and failure paths
4. Use meaningful test names and descriptions
5. Keep tests independent and isolated
### Benchmarking
1. Use realistic test data
2. Reset timer to exclude setup time
3. Run benchmarks for sufficient iterations
4. Compare results against baselines
5. Document performance expectations
### Performance Validation
1. Measure before and after optimizations
2. Validate mathematical accuracy is preserved
3. Test under realistic load conditions
4. Monitor memory allocation patterns
5. Profile CPU and memory usage
## Troubleshooting
### Common Test Issues
1. **Floating-point precision errors** - Use `assert.InDelta` for floating-point comparisons
2. **Race conditions** - Use `-race` flag to detect race conditions
3. **Timeout failures** - Increase test timeout for slow operations
4. **Resource leaks** - Ensure proper cleanup in test functions
### Benchmark Issues
1. **Unstable results** - Run benchmarks multiple times
2. **Insufficient iterations** - Increase benchmark time
3. **External interference** - Run benchmarks on isolated systems
4. **Measurement noise** - Use statistical analysis for comparison
