如何在React/Jest中模拟从自定义钩子返回数据？

import { renderHook } from '@testing-library/react-hooks';
import { useCustomHook } from './customHook';

jest.mock('./customHook');

test('should return data from custom hook', () => {
  useCustomHook.mockReturnValue({ data: 'mockedData' });
  
  const { result } = renderHook(() => useCustomHook());
  
  expect(result.current.data).toBe('mockedData');
});

import { renderHook } from '@testing-library/react-hooks';
import { useCustomHook } from './customHook';

test('should return data from custom hook', () => {
  const mockGetData = jest.spyOn(api, 'getData');
  mockGetData.mockReturnValue('mockedData');
  
  const { result } = renderHook(() => useCustomHook());
  
  expect(result.current.data).toBe('mockedData');
});

import { renderHook } from '@testing-library/react-hooks';
import { useCustomHook } from './customHook';

test('should return data from custom hook', () => {
  const mockCustomHook = () => ({ data: 'mockedData' });
  
  const { result } = renderHook(() => mockCustomHook());
  
  expect(result.current.data).toBe('mockedData');
});
