• selector - optional selector to scope the assertion to a nested element

The scrollable() assertion mirrors the corresponding interactor property and asserts that an element is scrollable in either the horizontal or vertical direction. If the corresponding property has been redefined, a new assertion is defined which does not accept a selector.

// with a scoped selector
await new Interactor('.page')

// without a scoped selector
await new Interactor('.has-overflow')

// when the corresponding property is overridden
@interactor class PageInteractor {
  scrollable = scrollable('.content')

// the scoped selector argument is no longer available
await new PageInteractor('.home-page')
