run-integration-tests.sh

#!/bin/bash

# Run integration tests - orchestrates the complete test workflow
# This script mimics the GitHub Actions workflow for local execution
#
# By default, this script runs integration tests in BOTH modes:
#   1. Default mode (monitoring tools disabled) - tests the user experience
#   2. Monitoring mode (monitoring tools enabled) - tests session_* tools
#
# Environment Variables:
#   MCP_MODE               - MCP transport mode (default: stdio, also: http)
#   HTTP_HOST              - Server host for HTTP mode (default: localhost)
#   HTTP_PORT              - Server port for HTTP mode (default: 3000)
#   TIMEOUT_SECONDS        - Request timeout (default: 30)
#   ENABLE_MONITORING_TOOLS - Force a specific mode instead of running both:
#                            "true"  = only run with monitoring tools enabled
#                            "false" = only run with monitoring tools disabled
#                            unset   = run BOTH modes (default)
#
# Usage:
#   ./run-integration-tests.sh                    # Run in BOTH modes (recommended)
#   ENABLE_MONITORING_TOOLS=false ./run-integration-tests.sh  # Only default mode
#   ENABLE_MONITORING_TOOLS=true ./run-integration-tests.sh   # Only monitoring mode
#   MCP_MODE=http ./run-integration-tests.sh      # Run using HTTP transport
#   ./run-integration-tests.sh --tools session_end            # Filter to specific tools
