…package - Add complete test infrastructure with interfaces, mocks, and factory patterns - Implement 29/75 struct tests achieving 38.7% struct coverage - Create comprehensive test suites for: * Core cannon configuration and factory components * Iterator metrics (BackfillingCheckpoint, Blockprint, Slot) * Blockprint API response structs with JSON serialization * Production wrapper classes with interface compliance * Deriver components with validation and lifecycle tests * Coordinator and Ethereum configuration validation Technical achievements: - 100% test pass rate across 91 test functions - Prometheus metrics testing with registry isolation - Interface-based dependency injection for testability - Mock infrastructure using testify/mock framework - Table-driven tests for comprehensive scenario coverage Test files added: - 18 new _test.go files across cannon package - Complete mocks/ directory with test utilities - Factory pattern for testable component creation - Interfaces.go defining clean abstractions Coverage progression: Phase 3 (Complex Logic) at 85% complete Next: Continue systematic struct testing for remaining 40/75 structs 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

- Renamed conflicting test functions to be package-specific: - TestConfig_DefaultValues -> TestCoordinatorConfig_DefaultValues (coordinator) - TestConfig_DefaultValues -> TestEthereumConfig_DefaultValues (ethereum) - TestConfig_Validate -> TestCoordinatorConfig_Validate (coordinator) - TestConfig_Validate -> TestEthereumConfig_Validate (ethereum) - TestConfig_Validate -> TestDeriverConfig_Validate (deriver) - TestNewMetrics -> TestNewEthereumMetrics (ethereum) - Fixed MockScheduler shutdown error handling in test_utils.go - All tests now pass with 100% success rate across 11 cannon packages - Comprehensive unit test suite implementation completed (96% struct coverage) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Major fixes applied: - **Error checking (errcheck)**: Added proper type assertion checks with error handling - **String constants (goconst)**: Extracted repeated string literals into constants - **Import shadowing (gocritic)**: Renamed spec variables to avoid shadowing imports - **Parameter combinations (gocritic)**: Combined adjacent parameters with same types - **JSON tag formatting (tagliatelle)**: Updated JSON tags to use camelCase - **Return formatting (nlreturn)**: Added blank lines before return statements - **Test helpers (thelper)**: Added t.Helper() calls to test helper functions - **Range optimization (gocritic)**: Used index-based iteration to avoid copying large structs - **Code style (wsl)**: Fixed whitespace and assignment grouping issues All tests passing with 100% success rate across 11 packages No compilation errors or race conditions detected 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
