"""Comprehensive Test Suite for Accessibility Engine Tools - Following Proven MCP Tool Test Pattern.
import logging
logging.basicConfig(level=logging.DEBUG)
This test suite validates the Accessibility Engine Tools functionality using the systematic
testing approach that achieved 100% success rate across multiple tool suites.
Test Coverage:
- Accessibility compliance testing with WCAG validation
- Assistive technology integration and compatibility testing
- WCAG compliance validation with multi-version support
- Accessibility report generation with multiple formats
- FastMCP integration with Context support and progress reporting
- Security validation for accessibility testing parameters
- Error handling for all failure scenarios and edge cases
- Property-based testing for robust input validation
Testing Strategy:
- Property-based testing with Hypothesis for comprehensive input coverage
- Mock-based testing for accessibility components and external integrations
- Security validation for accessibility testing parameters and configurations
- Integration testing scenarios with realistic accessibility operations
- Performance and timeout testing with accessibility operation limits
Key Mocking Pattern:
- Accessibility components: Mock CompliantValidator, WCAGAnalyzer, test runners
- Context: Mock progress reporting and logging operations
- Assistive technology: Mock integration manager and technology configurations
- Report generation: Mock report generator and export functionality
