# 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
|
||||
go test -coverprofile=coverage.out ./...
|
||||
```
|
||||
|
||||
#### Mathematical Function Tests
|
||||
```bash
|
||||
# Run only Uniswap pricing tests
|
||||
go test ./pkg/uniswap/...
|
||||
|
||||
# Run with verbose output
|
||||
go test -v ./pkg/uniswap/...
|
||||
|
||||
# Run with coverage
|
||||
go test -cover ./pkg/uniswap/...
|
||||
```
|
||||
|
||||
#### Specific Test Cases
|
||||
```bash
|
||||
# Run a specific test function
|
||||
go test -run TestSqrtPriceX96ToPrice ./pkg/uniswap/
|
||||
|
||||
# Run tests matching a pattern
|
||||
go test -run Test.*Price ./pkg/uniswap/
|
||||
```
|
||||
|
||||
### Running Benchmarks
|
||||
|
||||
#### Basic Benchmarks
|
||||
```bash
|
||||
# Run all benchmarks
|
||||
go test -bench=. ./...
|
||||
|
||||
# Run benchmarks with memory profiling
|
||||
go test -bench=. -benchmem ./...
|
||||
|
||||
# Run benchmarks with timing
|
||||
go test -bench=. -benchtime=5s ./...
|
||||
|
||||
# Run specific benchmark
|
||||
go test -bench=BenchmarkSqrtPriceX96ToPrice ./pkg/uniswap/
|
||||
```
|
||||
|
||||
#### Benchmark Analysis
|
||||
```bash
|
||||
# Run benchmarks and save results
|
||||
go test -bench=. -benchmem ./pkg/uniswap/ > benchmark_results.txt
|
||||
|
||||
# Compare benchmark results
|
||||
benchcmp old_results.txt new_results.txt
|
||||
```
|
||||
|
||||
## 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
|
||||
|
||||
## Future Improvements
|
||||
|
||||
### Testing Enhancements
|
||||
1. Property-based testing with `gopter` or similar libraries
|
||||
2. Fuzz testing for edge case discovery
|
||||
3. Load testing frameworks for stress testing
|
||||
4. Automated performance regression detection
|
||||
|
||||
### Benchmarking Improvements
|
||||
1. Continuous benchmark tracking
|
||||
2. Comparative benchmarking across versions
|
||||
3. Detailed profiling integration
|
||||
4. Resource usage monitoring
