Is this code a Unit or a End-to-End test?

Is the example bellow running Unit or a End-to-End tests. Should End-to-End tests always open a browser?

Scenario('search', async I => {
  I.say(`I wait for results to appear.`)
  I.wait4UrlToContain('#q=foo')
  I.wait4ElementVisible('.search-results__item', 20)

  I.wait4DataLayerEvent({
    eventInfo: {
      eventName: 'Onsite Search',
      eventAction: 'Success'
    },
   ...
  })
