How to use the @better-scroll/core/src/__tests__/__utils__/layout.mockDomClient function in @better-scroll/core

beforeEach(() => {
    // create Dom indicator
    const indicatorWrapper = document.createElement('div')
    const indicatorEl = document.createElement('div')
    indicatorWrapper.appendChild(indicatorEl)
    // mock clientHeight and clientWidth
    mockDomClient(indicatorWrapper, { height: 100, width: 100 })

    indicatorOptions = {
      wrapper: indicatorWrapper,
      direction: 'vertical' as Direction,
      fade: true,
      interactive: true
    }
  })
