"""Tests for the resource templating and user authentication system using FastMCP Client."""

"""Test resource templating functionality for dynamic resource generation.

🔧 MCP Tools Used:
- Resource templating engine: Generate dynamic resources from templates
- Template-based resources: Create resources using template patterns
- Resource validation: Validate generated resources
- Dynamic content generation: Generate content based on templates

🧪 What's Being Tested:
- Resource template engine functionality
- Dynamic resource generation from templates
- Template parameter substitution and validation
- Resource lifecycle management with templates
- Template inheritance and composition
- Error handling for invalid templates or parameters
- Performance of template-based resource generation

🔍 Potential Duplications:
- Template functionality overlaps with middleware template tests
- Resource management might overlap with service resource tests
- Dynamic generation patterns similar to other template-based tools
- Validation logic might be similar to other resource validation tests
