/** * GetFileDesignPatternTool Tests * * TESTING PATTERNS: * - Test tool metadata (name, description, schema) * - Test successful execution with valid inputs * - Test error handling with invalid inputs * - Test toolConfig option passing * - Mock external dependencies for isolation * * CODING STANDARDS: * - Use describe blocks to group related tests * - Use it with 'should...' naming pattern * - Test input validation and edge cases * - Verify ToolResult structure * - Check both success and error paths * - Mock external dependencies */ import { describe, it, expect, vi, beforeEach } from 'vitest';
