# E2E Integration Test Script for knot
# 
# This script tests the complete indexing and MCP query pipeline:
# 1. Spins up isolated Neo4j and Qdrant instances on high ports (17xxx/16xxx)
# 2. Indexes test files from tests/testing_files/
# 3. Queries the MCP server to validate decorator and type reference extraction
# 4. Cleans up containers and data
#
# Usage: ./tests/run_e2e.sh
# Requirements: docker, docker-compose, jq (optional for JSON parsing)
