"""Comprehensive Test Suite for File Operation Tools - Following Proven MCP Tool Test Pattern. logging.basicConfig(level=logging.DEBUG) This test suite validates the File Operation Tools functionality using the systematic testing approach that achieved 100% success rate across 9 tool suites. Test Coverage: - File operation functionality with comprehensive validation (copy, move, delete, rename, create_folder, get_info) - Path security validation and sanitization - Permission checking and error handling - Transaction safety and rollback capability - Backup creation for destructive operations - Security validation for file operations - Property-based testing for robust input validation - Integration testing with mocked file system operations - Error handling for all failure scenarios - Performance testing for file operation limits Testing Strategy: - Property-based testing with Hypothesis for comprehensive input coverage - Mock-based testing for file system operations and security validation - Security validation for path traversal prevention - Integration testing scenarios with realistic file operations - Performance and safety testing with operation limits """ from __future__ import annotations import logging from datetime import timedelta from typing import TYPE_CHECKING, Any from unittest.mock import AsyncMock, Mock, patch import pytest from fastmcp import Context from hypothesis import HealthCheck, assume, given, settings from hypothesis import strategies as st from hypothesis.strategies import composite #
