SSH Integration Tests (`ssh.test.ts`) **Comprehensive SSH functionality testing:** - ✅ Password authentication (valid/invalid credentials) - ✅ SSH key authentication (private key, invalid key handling) - ✅ Command execution (simple, sequential, long-running commands) - ✅ Session persistence (environment variables, working directory) - ✅ Connection pooling (reuse, limits, cleanup) - ✅ Error handling (connection refused, auth failures, timeouts) - ✅ Configuration options (custom ports, IPv6, host key checking) - ✅ Integration with ConsoleManager **Key Features:** - Tests both authentication methods with realistic scenarios - Validates command execution and output capture - Ensures session state persistence across operations - Tests connection pool management under various conditions - Comprehensive error handling and recovery testing ### 2. Session Management Tests (`session-management.test.ts`) **Session lifecycle and resource management:** - ✅ Concurrent session limits (enforcement, rapid creation/destruction) - ✅ Session recovery after crashes (detection, cleanup, restart) - ✅ State transitions (status changes, metadata preservation) - ✅ Resource cleanup (processes, buffers, monitoring resources) - ✅ Memory leak prevention (buffer limits, garbage collection) **Key Features:** - Tests system behavior under high concurrent load - Validates proper resource cleanup and leak prevention - Ensures graceful handling of session failures - Tests state management throughout session lifecycle - Performance monitoring and resource optimization ### 3. Error Detection Tests (`error-detection.test.ts`) **Multi-language error pattern matching:** - ✅ JavaScript/Node.js errors (stack traces, exceptions) - ✅ Python errors (tracebacks, syntax errors) - ✅ Java errors (stack traces, null pointers) - ✅ C/C++ errors (segmentation faults, assertions) - ✅ Compilation errors (across languages) - ✅ Database and network errors - ✅ Severity classification (critical, high, medium, low) - ✅ Performance under high error rates - ✅ Custom error patterns **Key Features:** - Comprehensive error pattern library for multiple languages - Intelligent severity scoring and classification - High-performance error detection (handles 100+ errors efficiently) - Extensible custom pattern system - Recovery strategy suggestions based on error types ### 4. Load and Stress Tests (`load.test.ts`) **Performance and scalability testing:** - ✅ 50+ concurrent sessions (creation, management, cleanup) - ✅ Memory usage monitoring (leak detection, efficient cleanup) - ✅ Connection pool saturation (limits, recovery) - ✅ Performance benchmarks (session creation speed, throughput) - ✅ System recovery under extreme load - ✅ Mixed workload scenarios - ✅ Real-time performance monitoring **Key Performance Targets:** - Session creation: < 100ms average per session - Concurrent sessions: Support 50+ simultaneous sessions - Memory efficiency: < 10MB per session average - Error detection: > 20 commands/second processing - Command throughput: > 100 commands/minute per session ### 5. Mock Infrastructure (`SSHServer.ts`) **Sophisticated mock SSH server:** - ✅ Password and key authentication simulation - ✅ Command processing (bash/shell commands) - ✅ Session state management - ✅ Connection management (multiple concurrent connections) - ✅ Failure mode simulation (network issues, auth failures) - ✅ Performance testing capabilities - ✅ Realistic SSH protocol behavior **Mock Capabilities:** - Simulates real SSH server without external dependencies - Supports common Unix/Linux commands (echo, ls, cd, pwd, etc.) - Environment variable and working directory persistence - Configurable failure modes for resilience testing - Performance metrics and connection management ## CI/CD Integration ### Test Workflow (`.github/workflows/test.yml`) **Comprehensive CI/CD pipeline:** - ✅ Multi-platform testing (Ubuntu, Windows, macOS) - ✅ Multiple Node.js versions (18, 20, 21) - ✅ Separate test categories (unit, integration, SSH, stress) - ✅ Security scanning (CodeQL, npm audit) - ✅ Docker containerization testing - ✅ Cross-platform shell compatibility - ✅ Performance benchmarking - ✅ Coverage reporting **Workflow Jobs:** 1. **Unit Tests**: Fast feedback on individual components 2. **Integration Tests**: Cross-platform real-world scenarios 3. **SSH Tests**: Dedicated SSH server setup and testing 4. **Stress Tests**: Performance validation and limit testing 5. **Security Scan**: Vulnerability and security analysis 6. **Docker Tests**: Containerization and deployment testing 7. **Benchmark Tests**: Performance metrics collection ### Release Workflow (`.github/workflows/release.yml`) **Automated release pipeline:** - ✅ Pre-release test validation - ✅ NPM package publishing - ✅ Docker image building and publishing - ✅ GitHub release creation - ✅ Documentation updates - ✅ Post-release verification ## Test Execution ### Available Test Scripts ```bash # Run all tests npm test # Run specific test categories npm run test:unit # Unit tests only npm run test:integration # Integration tests only npm run test:stress # Stress tests only # Run specific test files npm run test:ssh # SSH integration tests npm run test:sessions # Session management tests npm run test:errors # Error detection tests npm run test:load # Load testing # Development workflows npm run test:watch # Watch mode for development npm run test:coverage # Generate coverage reports ``` ### Jest Configuration Features -
