class DummyJob < Wayfarer::Base
  route.to :index

    # Mind the explicit return
    browser.execute_script("return [window.scrollX, window.scrollY]")
  end
end

class DummyJob < Wayfarer::Base
  route.to :index

  def index
    # Capybara does not return value of JavaScript execution
    browser.execute_script("console.log('Foobar')") # => nil
  end
