"""Test Sampling Middleware Integration using FastMCP Client SDK."""

"""Test sampling middleware for request/response monitoring and analysis.

🔧 MCP Tools Used:
- Sampling middleware: Monitor and sample MCP requests/responses
- Data collection: Capture tool usage patterns and metrics
- Performance monitoring: Track tool execution times and patterns
- Usage analytics: Analyze tool usage statistics

🧪 What's Being Tested:
- Request/response sampling functionality
- Data collection accuracy and completeness
- Performance impact of sampling middleware
- Statistical analysis of tool usage patterns
- Sampling rate configuration and optimization
- Data storage and retrieval mechanisms
- Privacy and security considerations for sampled data

🔍 Potential Duplications:
- Performance monitoring overlaps with other performance tests
- Middleware testing patterns similar to template middleware tests
- Data collection might overlap with analytics and logging functionality
- Usage tracking might be similar to other monitoring systems
