isNotVisible(timeout:number=5000)

Waits until component is not visible. The test will continue to retry until component is not visible or until the timeout. Test fails if passes the timeout. isNotVisible would be true if the element exists in the DOM but not visible to the user.

import {Component, field, defaults} from "xenon";

@defaults({css:"#app"})
class MyApp extends Component {
  @field(Component, {css:".progress"})
  progressBar:Component
}

it("test that eventually progress bar is not visible", ()=> {
  let app = new MyApp()
  // wait for up to 3 seconds for the progress to not show
  expect(app.someLoader.isNotVisible(3000))
})
