Architecture

Dual-Port Design

  • Business Port (8000): Serves mock API endpoints
  • Admin Port (8001): Management interface and logging
  • No Path Conflicts: Eliminates /admin endpoint conflicts

Database Schema

  • Request Logs: Complete request/response audit trail
  • Test Sessions: Stateful test execution tracking
  • Compliance Events: Regulatory compliance monitoring
  • Performance Metrics: Response time and throughput data
