"""
Comprehensive tests for MCP Server for Splunk using FastMCP in-memory testing.

This test suite covers:
- Core server functionality
- All tools (health, search, admin, metadata, kvstore)
- All resources (splunk_config, splunk_docs)
- All prompts (troubleshooting)
- Server lifecycle and middleware
- Client configuration handling
