# Claude Sonnet 4 Thinking Model: Go MCP Server Testing Framework Implementation ## Project Overview You are working on a Go-based Model Context Protocol (MCP) server project that is undergoing a comprehensive testing framework modernization. The project currently has a mix of PowerShell legacy tests and modern Go tests, with significant progress made in organizing the testing structure. ## Current State Assessment Before beginning any work, you MUST: 1. **Read the Migration Status Document**: - File: `c:\Users\James\Documents\go-dev-mcp\scripts\testing\MIGRATION_STATUS.md` - This document tracks all completed work and outstanding tasks - Use this as your primary reference for current state 2. **Review the Organization Summary**: - File: `c:\Users\James\Documents\go-dev-mcp\scripts\testing\ORGANIZATION_SUMMARY.md` - This explains the current directory structure and organization 3. **Explore the Current Directory Structure**: - Use `d94_directory_tree` to examine `c:\Users\James\Documents\go-dev-mcp\scripts\testing` - Use `d94_list_directory` to understand the current file layout - Use `d94_read_file` to examine key files and understand the current implementations ## Primary Objectives Based on the Migration Status document, implement the following next steps in order of priority: ### Phase 1: End-to-End Testing Infrastructure (High Priority) **Objective**: Implement comprehensive E2E tests with mock server capability #### Task 1.1: Mock Server Implementation - **Location**: Create new files in `c:\Users\James\Documents\go-dev-mcp\internal\testing\mock\` - **Requirements**: - Implement a mock MCP server that can simulate real server responses - Support for all tool operations (go_run, go_build, go_test, go_fmt, go_mod) - Configurable response scenarios (success, failure, timeout) - JSON-RPC 2.0 protocol compliance for MCP - **Files to Create**: - `mock_server.go` - Main mock server implementation - `mock_responses.go` - Predefined response templates - `mock_config.go` - Configuration for different test scenarios - **Parallel Work**: Can be developed independently #### Task 1.2: E2E Test Framework - **Location**: Update `c:\Users\James\Documents\go-dev-mcp\scripts\testing\legacy\core\e2e_test.ps1` - **Requirements**: - Convert PowerShell E2E test to Go implementation - Integration with mock server from Task 1.1 - Test full request-response cycles - Validation of JSON-RPC protocol compliance - **Files to Create/Update**: - `c:\Users\James\Documents\go-dev-mcp\scripts\testing\e2e_test.go` - Update migration status table to mark E2E tests as complete - **Dependencies**: Requires completion of Task 1.1 #### Task 1.3: Integration Test Enhancement - **Location**: Update `c:\Users\James\Documents\go-dev-mcp\scripts\testing\integration_test.go` - **Requirements**: - Complete the "In Progress" integration tests - Add edge case coverage - Implement comprehensive error handling tests - Add timeout and resource limit testing - **Parallel Work**: Can work on this while Tasks 1.1-1.2 are in progress ### Phase 2: Test Metrics and Coverage (Medium Priority) **Objective**: Implement comprehensive test metrics collection and reporting #### Task 2.1: Test Metrics Collection Utility - **Location**: Create `c:\Users\James\Documents\go-dev-mcp\scripts\testing\metrics\` - **Requirements**: - Go-based test metrics collector - Coverage report generation - Performance benchmarking - Test execution time tracking - Integration with existing test runners - **Files to Create**: - `metrics_collector.go` - Main metrics collection logic - `coverage_reporter.go` - Coverage report generation - `benchmark_runner.go` - Performance testing utilities - `report_generator.go` - HTML/JSON report generation - **Parallel Work**: Can be developed independently #### Task 2.2: Coverage Enhancement - **Location**: Update existing test files - **Requirements**: - Increase test coverage from ~70% to 90% target - Add missing test cases for edge conditions - Implement property-based testing for complex scenarios - Add stress testing for concurrent operations - **Strategy**: Work on this incrementally across all existing test files ### Phase 3: Directory Structure Optimization (Medium Priority) **Objective**: Complete the directory organization improvements #### Task 3.1: Hybrid Strategy Directory Organization - **Location**: `c:\Users\James\Documents\go-dev-mcp\scripts\testing\legacy\strategies\` - **Requirements**: - Create `hybrid/` subdirectory matching the `direct/` structure - Move all hybrid-related tests to the new subdirectory - Update all references and script paths - Maintain backward compatibility - **Files to Move/Update**: - Move `hybrid_strategy_test.ps1` to `hybrid/hybrid_strategy_test.ps1` - Move `hybrid_strat_verify.ps1` to `hybrid/hybrid_strat_verify.ps1` - Update `run_tests.ps1` references - Update `run_strategy_tests.ps1` references - **Parallel Work**: Can be done independently #### Task 3.2: Documentation Updates - **Location**: Update documentation files - **Requirements**: - Update `ORGANIZATION_SUMMARY.md` to reflect hybrid directory changes - Update main project documentation - Create comprehensive testing guide - Document new testing patterns and best practices - **Dependencies**: Should be done after Task 3.1 ### Phase 4: Advanced Testing Features (Lower Priority) **Objective**: Implement advanced testing capabilities #### Task 4.1: Comprehensive Strategy Testing - **Location**: Expand existing strategy tests - **Requirements**: - Add more test scenarios for direct and hybrid strategies - Implement cross-platform testing scenarios - Add performance comparison between strategies - Test edge cases and error conditions - **Parallel Work**: Can be developed independently #### Task 4.2: API Boundary Testing - **Location**: Create new test category - **Requirements**: - Test MCP protocol boundaries - Validate JSON-RPC 2.0 compliance - Test serialization/deserialization - Add malformed request handling tests - **Files to Create**: - `c:\Users\James\Documents\go-dev-mcp\scripts\testing\api_boundary_test.go` - Add new category to migration status table ## Implementation Guidelines ### Parallel Development Strategy 1. **Independent Workstreams**: Tasks 1.1, 2.1, 3.1, and 4.1 can be developed in parallel 2. **Dependent Tasks**: Tasks 1.2 depends on 1.1; Task 3.2 depends on 3.1 3. **Incremental Tasks**: Task 2.2 should be worked on continuously across phases ### File Management Approach - **Use filesystem tools extensively**: `d94_read_file`, `d94_write_file`, `d94_create_directory` - **Check current state before changes**: Always read files before modifying - **Update migration status**: After completing each task, update the migration status document - **Create before modifying**: Use `d94_create_file` for new files, `d94_edit_file` for modifications ### Progress Tracking Requirements After completing each major task: 1. **Update Migration Status Table**: Mark completed items as ✅ Complete 2. **Update Progress Metrics**: Recalculate percentages and counts 3. **Add Recent Changes Entry**: Document what was accomplished 4. **Update Next Steps**: Remove completed items, add new discoveries 5. **Update Last Modified Date**: Keep the timestamp current ### Quality Standards - **Go Code**: Follow Go best practices, proper error handling, comprehensive comments - **PowerShell Scripts**: Follow PowerShell best practices, proper error handling - **Tests**: Each test should be isolated, repeatable, and well-documented - **Documentation**: Keep all documentation current and comprehensive ### Validation Requirements For each completed task: 1. **Run existing tests**: Ensure no regressions 2. **Test new functionality**: Verify new features work as expected 3. **Update documentation**: Ensure docs reflect new state 4. **Cross-platform considerations**: Test on Windows environment specifically ## Starting Instructions 1. **Begin with State Assessment**: Read the migration status document and understand current state 2. **Choose Starting Point**: Pick the highest priority task that can be worked on independently 3. **Create Work Plan**: Break your chosen task into smaller subtasks 4. **Track Progress**: Update migration status as you make progress 5. **Test Continuously**: Run tests frequently to catch issues early ## Key Files to Monitor - `c:\Users\James\Documents\go-dev-mcp\scripts\testing\MIGRATION_STATUS.md` - Primary tracking document - `c:\Users\James\Documents\go-dev-mcp\scripts\testing\ORGANIZATION_SUMMARY.md` - Structure documentation - `c:\Users\James\Documents\go-dev-mcp\scripts\testing\run_tests.ps1` - Main test runner - All files in `c:\Users\James\Documents\go-dev-mcp\scripts\testing\legacy\` - Legacy test structure ## Success Criteria - All items in "Next Steps" section are completed and marked as ✅ - Test coverage reaches 90% target - All PowerShell tests are successfully migrated to Go - Directory structure is fully organized and consistent - Documentation is comprehensive and up-to-date - Mock server enables comprehensive E2E testing - Metrics collection provides valuable insights into test performance Remember: Work incrementally, test frequently, document thoroughly, and update the migration status document as you progress. Use the filesystem tools to maintain awareness of the current state and make changes systematically.
