Rails testing button functionality with capybara.

I have this code, I am trying to click on the button to test its functionality using guard and capybara. I get an undefined method error on guard when I have it written like this. It comes back with no errors if I comment out the click_button line. It should render a response that the import was successful as well which is being displayed by an index page.

require 'rails_helper'
require 'spec_helper'

RSpec.describe "Imports", type: :request do
  it "checks the import page." do
    get '/imports'
    click_button "submit"
  end
end
