松散匹配中的一个值开玩笑的

我有一个分析追踪器,只会调用后1秒和一个对象,其中 intervalInMilliseconds (持续时间)值为 确定性。

我怎么用 jest.toHaveBeenCalledWith

 test('pageStats - publicationPage (will wait 1000ms)', done => {
  const track = jest.fn()

  const expected = new PayloadTiming({
    category: 'PublicationPage',
    action: 'PublicationPage',
    name: 'n/a',
    label: '7',
    intervalInMilliseconds: 1000 // or around
  })

  mockInstance.viewState.layoutMode = PSPDFKit.LayoutMode.SINGLE
  const sendPageStats = pageStats({
    instance: mockInstance,
    track,
    remoteId: nappConfig.remoteId
  })

  mockInstance.addEventListener('viewState.currentPageIndex.change', sendPageStats)

  setTimeout(() => {
    mockInstance.fire('viewState.currentPageIndex.change', 2)

    expect(track).toHaveBeenCalled()
    expect(track).toHaveBeenCalledWith(expected)

    done()
  }, 1000)

  expect(track).not.toHaveBeenCalled()
})

expect(track).toHaveBeenCalledWith(expected) 失败原因:

Expected mock function to have been called with:
      {"action": "PublicationPage", "category": "PublicationPage", "intervalInMilliseconds": 1000, "label": "7", "name": "n/a"}
    as argument 1, but it was called with
      {"action": "PublicationPage", "category": "PublicationPage", "intervalInMilliseconds": 1001, "label": "7", "name": "n/a"}

jest-extended 但是我没有看到任何对我的用例有用的东西。
