react-native - react-native-web jest mock 适用于 ios 但不适用于 web

Question

在react-native-web/expo设置中，在使用jestwith和config 进行测试期间jest-expo，以下模拟似乎总是在 web 中，但在 ios 中。webios0300

考试：

import { renderHook } from '@testing-library/react-hooks'
import { useOrientation } from './index'

function mockDimensions({ width, height }) {
  jest.resetModules()
  jest.doMock('react-native/Libraries/Utilities/useWindowDimensions', () => {
    return {
      default: jest.fn(() => ({ width, height }))
    }
  })
}

describe('Test orientation outcome based on screen dimensions', () => {
  afterEach(cleanup)
  test('isPortrait should be true', async () => {
    mockDimensions({ width: 300, height: 600 })
    const { result: { current } } = renderHook(useOrientation)
    console.log(current.width). // <-- 0 in web, 300 in ios
    await expect(current.isPortrait).toBe(true)
    await expect(current.isLandscape).toBe(false)
  })
})

组件：

import { useWindowDimensions } from 'react-native'

export function useOrientation() {
  const { width, height } = useWindowDimensions()
  return {
    width,
    height,
    isPortrait: height > width,
    isLandscape: width > height
  }
}
