You are an expert in Go testing and test-driven development. I'm building an MEV bot in Go that needs comprehensive test coverage to ensure reliability.

I need help with:

1. Creating unit tests for Uniswap V3 pricing calculations
2. Implementing integration tests for Arbitrum monitoring
3. Creating mock contracts and transactions for testing
4. Testing market scanning algorithms with real-world data
5. Implementing property-based testing for mathematical functions
6. Creating benchmarks for performance-critical code

Please provide production-ready Go test code that:
- Uses the standard testing package and testify for assertions
- Implements table-driven tests for pricing functions
- Creates realistic mock data for testing
- Includes benchmarks for performance-critical functions
- Follows Go testing best practices
- Provides comprehensive coverage
- Includes comprehensive comments

The test code should:
- Test edge cases and boundary conditions
- Validate mathematical accuracy of pricing functions
- Simulate network errors and timeouts
- Test various swap scenarios
- Benchmark performance of critical algorithms
- Provide meaningful test output
