# E2E Integration Test Script for Kotlin Support in knot (v0.7.0)
#
# This script tests Kotlin-specific features:
# 1. Spins up isolated Neo4j and Qdrant instances on high ports (17xxx/16xxx)
# 2. Indexes Kotlin test file (sample.kt)
# 3. Queries via MCP to validate Kotlin entity extraction
# 4. Tests class, interface, object, function, and annotation extraction
# 5. Cleans up containers and data
#
# Usage: ./tests/run_kotlin_e2e.sh
# Requirements: docker, docker-compose

set -e  # Exit on error
