/**
 * Fetch mock utilities for testing
 *
 * Provides utilities for mocking the global fetch function.
 * For more complex scenarios, consider using MSW (Mock Service Worker).
 *
 * @example
 * ```typescript
 * // Simple mock
 * const mockFetch = setupFetchMock({ data: 'test' });
 *
 * // Make request
 * const response = await fetch('/api/test');
 * const data = await response.json();
 *
 * // Assert
 * expect(data).toEqual({ data: 'test' });
 * expect(mockFetch.calls).toHaveLength(1);
 *
 * // Reset
 * mockFetch.restore();
 * ```
