# ==============================================================================
# LightRAG E2E Test Runner
# ==============================================================================
# This script runs the End-to-End test suite for LightRAG.
# It supports multiple storage backends and configurable LLM models.
#
# Usage: ./e2e/run_isolation_test.sh [options]
#
# Options:
#   -b, --backend <type>    Storage backend to test (file, postgres, all). Default: file
#   -m, --model <name>      Ollama model to use. Default: gpt-oss:20b
#   -d, --dim <number>      Embedding dimension. Default: 1024
#   -h, --help              Show this help message
# ==============================================================================
