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

The focusable() assertion mirrors the corresponding interactor property and asserts that an element has a non-negative tabindex. 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('.login-form')

// without a scoped selector
await new Interactor('.link-to')

// when the corresponding property is overridden
@interactor class FieldInteractor {
  focusable = focusable('input')

// the scoped selector argument is no longer available
await new FieldInteractor('.name-field')
