# MCP Server Comprehensive Testing Strategy ## Executive Summary This document outlines a comprehensive testing strategy to build robust test harnesses for all 45 MCP server tools. The strategy addresses the current 68.89% failure rate by creating systematic, automated testing infrastructure that validates each tool's functionality, parameter handling, and error cases. ## Current State Analysis ### Failed Tools (31/45 = 68.89%) - **Parameter Validation Issues**: 30/31 failures due to missing required parameters - **Core Issue**: Lack of comprehensive test data and validation framework - **Root Cause**: No systematic approach to test all tool combinations and edge cases ### Test Coverage Requirements 1. **Core Ethereum Operations** (22 tools) - Block queries, wallet management, utilities 2. **ERC20 Token Operations** (7 tools) - Token info, balances, transfers, approvals 3. **ERC721 NFT Operations** (9 tools) - NFT info, ownership, metadata, transfers 4. **ERC1155 Multi-Token Operations** (3 tools) - Multi-token balances and operations 5. **Network & Configuration** (3 tools) - Network discovery and configuration 6. **Guidance & Help** (1 tool) - ENS resolution guidance ## Testing Architecture ### 1. Test Infrastructure Components #### A. Test Blockchain Environment - **Primary**: Hardhat Network (local test blockchain) - **Secondary**: Ganache CLI (backup/alternative) - **Requirements**: - Fast transaction processing - Deterministic behavior - Account/wallet management - Contract deployment capabilities - Block mining control #### B. Test Contract Suite ``` contracts/test/ ├── TestERC20.sol # Comprehensive ERC20 test token ├── TestERC721.sol # NFT collection for testing ├── TestERC1155.sol # Multi-token contract ├── TestWallet.sol # Wallet contract for advanced testing └── TestOracle.sol # Price/data oracle for complex scenarios ``` #### C. MCP Client Test Framework ``` tests/framework/ ├── MCPTestClient.ts # Core MCP protocol client ├── TestRunner.ts # Test execution engine ├── Assertions.ts # Custom assertion library ├── TestData.ts # Test data management └── Validators.ts # Response validation ``` #### D. Test Data Management ``` tests/data/ ├── accounts.json # Test wallet addresses and keys ├── contracts.json # Deployed contract addresses ├── testCases/ # Organized test case definitions │ ├── core/ # Core Ethereum operations │ ├── erc20/ # ERC20 token tests │ ├── erc721/ # NFT tests │ ├── erc1155/ # Multi-token tests │ └── network/ # Network operation tests └── expected/ # Expected responses for validation ``` ### 2. Test Categories & Strategies #### A. Core Ethereum Operations (22 tools) **Test Strategy**: Integration tests against live test blockchain - **Network Operations**: Test with multiple networks (mainnet, testnet, local) - **Wallet Operations**: Generate, load, validate test wallets - **Transaction Operations**: Create, sign, broadcast test transactions - **Utility Operations**: Format/parse operations with known values - **ENS Operations**: Test with known ENS names and addresses #### B. Token Operations (ERC20/721/1155) (19 tools) **Test Strategy**: Contract deployment and interaction testing - **Pre-deployment**: Deploy test contracts with known properties - **Balance Testing**: Transfer tokens and verify balance changes - **Approval Testing**: Test approval workflows - **Metadata Testing**: Verify token/NFT metadata retrieval - **Transfer Testing**: Execute and validate transfers #### C. Network & Configuration (3 tools) **Test Strategy**: Configuration validation and network discovery - **Network Discovery**: Validate supported networks list - **Network Details**: Test network information retrieval - **Configuration**: Validate provider settings #### D. Error Handling & Edge Cases **Test Strategy**: Comprehensive negative testing - **Invalid Parameters**: Test all parameter validation - **Network Failures**: Simulate network issues - **Contract Failures**: Test with non-existent contracts - **Permission Failures**: Test unauthorized operations ### 3. Parallel Development Streams #### Stream 1: Test Infrastructure & Blockchain Setup **Responsibility**: Set up core testing infrastructure - Hardhat environment configuration - Test contract development and deployment - Test account management - Basic blockchain utilities #### Stream 2: MCP Client Test Framework **Responsibility**: Build MCP testing tools - MCP protocol client implementation - Test execution framework - Response validation system - Test case management #### Stream 3: Test Case Development & Validation **Responsibility**: Create comprehensive test suites - Test case definitions for all 45 tools - Expected response validation - Error case testing - Integration test workflows ### 4. Test Execution Strategy #### Phase 1: Unit Testing (Individual Tools) - Test each tool in isolation - Validate parameter handling - Verify response formats - Test error conditions #### Phase 2: Integration Testing (Tool Combinations) - Test workflows requiring multiple tools - Validate state changes across tools - Test transaction sequences - Verify data consistency #### Phase 3: End-to-End Testing (Complete Scenarios) - Full user workflows - Complex multi-step operations - Performance testing - Stress testing #### Phase 4: Regression Testing (Continuous) - Automated test execution - Change detection - Performance monitoring - Error tracking ## Test Data Requirements ### 1. Test Accounts ```javascript { "deployer": { address: "0x...", privateKey: "0x..." }, "user1": { address: "0x...", privateKey: "0x..." }, "user2": { address: "0x...", privateKey: "0x..." }, "receiver": { address: "0x...", privateKey: "0x..." } } ``` ### 2. Test Contracts ```javascript { "TestERC20": { "address": "0x...", "name": "Test Token", "symbol": "TEST", "decimals": 18, "totalSupply": "1000000000000000000000000" }, "TestERC721": { "address": "0x...", "name": "Test NFT", "symbol": "TNFT", "baseURI": "https://test.com/metadata/" } } ``` ### 3. Test Scenarios ```javascript { "erc20_transfer": { "description": "Transfer ERC20 tokens between accounts", "steps": [ { "tool": "getERC20Balance", "params": {...}, "expected": {...} }, { "tool": "transferERC20", "params": {...}, "expected": {...} }, { "tool": "getERC20Balance", "params": {...}, "expected": {...} } ] } } ``` ## Success Criteria ### Quantitative Metrics - **Tool Success Rate**: Target >95% (from current 31.11%) - **Test Coverage**: 100% of tools with comprehensive test cases - **Response Time**: <5 seconds average per tool call - **Error Handling**: 100% of error conditions tested and validated ### Qualitative Metrics - All tools have clear, documented test cases - Test framework is maintainable and extensible - Testing can be run locally and in CI/CD - Results are clearly reported and actionable ## Implementation Timeline ### Phase 1: Foundation (Week 1) - Set up Hardhat environment - Deploy basic test contracts - Implement MCP test client - Create test data structures ### Phase 2: Core Testing (Week 2) - Implement tests for core Ethereum operations - Build token operation test suites - Create validation framework - Implement error testing ### Phase 3: Integration (Week 3) - End-to-end workflow testing - Performance testing - Stress testing - Documentation and reporting ### Phase 4: Automation (Week 4) - CI/CD integration - Automated reporting - Monitoring and alerting - Continuous improvement ## Risk Mitigation ### Technical Risks - **Network Dependency**: Use local Hardhat network for deterministic testing - **Contract Complexity**: Start with simple contracts, expand gradually - **MCP Protocol Changes**: Abstract protocol handling into reusable components - **Test Maintenance**: Design for maintainability and clear documentation ### Operational Risks - **Resource Requirements**: Ensure adequate testing infrastructure - **Team Coordination**: Clear communication and work stream boundaries - **Timeline Pressure**: Prioritize critical tools first, expand coverage iteratively ## Conclusion This comprehensive testing strategy addresses the root causes of the current 68.89% failure rate by providing: 1. **Systematic Test Coverage**: Every tool tested with appropriate scenarios 2. **Realistic Test Environment**: Local blockchain with deployed test contracts 3. **Automated Validation**: Consistent, repeatable testing framework 4. **Comprehensive Error Testing**: All edge cases and error conditions covered The parallel development approach ensures rapid implementation while maintaining quality through systematic validation at each step. --- **Next Steps**: Split this strategy into three parallel development streams and implement using TDD methodology with comprehensive validation.
