} ``` **MockToolsetManager**: Simulates toolset manager behavior for integration testing ```typescript class MockToolsetManager { setCurrentToolset(config) { /* track toolset changes */ } getCurrentToolset() { /* return active toolset */ } unequipToolset() { /* cleanup */ } } ``` **MockMcpConfigHandlers**: Provides MCP configuration management for testing ```typescript class MockMcpConfigHandlers { getCurrentConfig() { /* return current MCP config */ } setCurrentConfig(config) { /* update MCP config */ } restartConnections() { /* simulate restart */ } } ``` ### Test Environment Tests use `TestEnvironment` with memfs for isolated file system operations: ```typescript beforeEach(async () => { env = new TestEnvironment('/tmp/hypertool-test-persona'); await env.setup(); // Create test personas in memfs await setupTestPersonas(); }); ``` ### Test Data Each test suite creates realistic test personas with various configurations: - **Valid personas**: Complete personas with toolsets and metadata - **Invalid personas**: Malformed YAML or missing required fields - **Complex personas**: Multiple toolsets and MCP configurations - **Minimal personas**: Basic personas for simple testing ## Running Integration Tests ### Run All Integration Tests ```bash npm test -- test/integration/persona-*.test.ts ``` ### Run Specific Test Suite ```bash # Core integration tests (reliable) npm test -- test/integration/persona-core.test.ts # Toolset integration tests npm test -- test/integration/persona-toolset.test.ts # MCP config integration tests npm test -- test/integration/persona-mcp-config.test.ts # Discovery integration tests npm test -- test/integration/persona-discovery.test.ts # CLI integration tests npm test -- test/integration/persona-cli.test.ts ``` ### Run with Coverage ```bash npm test -- test/integration/ --coverage ``` ## Test Status and Known Issues ### Working Tests ✅ - **persona-core.test.ts**: All core integration functionality working - Core persona manager initialization and component integration - Error handling and recovery scenarios - Concurrent operation safety - Resource management and cleanup ### Partial Implementation ⚠️ - **persona-toolset.test.ts**: Basic functionality working, discovery integration needs refinement - **persona-mcp-config.test.ts**: Mock handlers working, real integration needs environment fixes - **persona-discovery.test.ts**: Core discovery working, file system integration needs memfs fixes - **persona-cli.test.ts**: Command structure working, execution needs mock improvements ### Known Issues 1. **Discovery Integration**: Real file system discovery with memfs needs better integration 2. **Event Handling**: Event emission timing in test environment needs adjustment 3. **CLI Command Execution**: Commander.js command execution in tests needs better mocking 4. **Async Operation Timing**: Some tests need better async operation coordination ## Future Improvements ### Short Term 1. Fix memfs integration for reliable file system operations 2. Improve mock component fidelity to match real implementations 3. Add better async operation coordination in tests 4. Enhance CLI command execution testing ### Long Term 1. Add performance benchmarking integration tests 2. Create integration tests for persona import/export 3. Add network operation testing for MCP connections 4. Create integration tests for persona validation workflows ## Integration Test Patterns ### Component Integration Pattern ```typescript describe('Component Integration', () => { let personaManager: PersonaManager; let toolsetManager: MockToolsetManager; let discoveryEngine: MockToolDiscoveryEngine; beforeEach(async () => { // Setup all components toolsetManager = new MockToolsetManager(); discoveryEngine = new MockToolDiscoveryEngine(); personaManager = new PersonaManager({ toolsetManager, toolDiscoveryEngine: discoveryEngine, }); await personaManager.initialize(); }); it('should integrate components correctly', async () => { // Test integration behavior }); }); ``` ### Event Integration Pattern ```typescript it('should emit events during integration workflows', async () => { const events: any[] = []; personaManager.on(PersonaEvents.PERSONA_ACTIVATED, (event) => { events.push(event); }); await personaManager.activatePersona('test-persona'); expect(events).toHaveLength(1); expect(events[0].persona.name).toBe('test-persona'); }); ``` ### Error Integration Pattern ```typescript it('should handle integration errors gracefully', async () => { // Setup component to fail toolsetManager.setCurrentToolset = vi.fn().mockRejectedValue( new Error('Toolset application failed') ); const result = await personaManager.activatePersona('test-persona'); expect(result.success).toBe(false); expect(result.errors).toContain('Toolset application failed'); }); ``` ## Conclusion The integration test suite provides comprehensive coverage of persona system integration with existing hypertool-mcp components. The core integration tests (`persona-core.test.ts`) are fully functional and provide confidence in the essential integration points. The other test suites provide extensive coverage but need refinement for full CI reliability. The integration tests demonstrate that: 1. ✅ The persona system integrates correctly with core hypertool-mcp components 2. ✅ Component lifecycle management works properly 3. ✅ Error handling and recovery mechanisms function correctly 4. ✅ The system handles resource constraints and concurrent operations safely 5. ⚠️ Advanced features like discovery, MCP config merging, and CLI integration are implemented but need environment refinement This integration test suite serves as both validation of the persona system integration and documentation of the expected integration behavior between components.
