Rspec/Capybara: How to "expect to see Routing Error"?

Question

How do I tell RSpec/Capybara to expect a RoutingError? The reason is I want users to click a link to "claim a plate" via PUT, not via GET/visiting the path.

Basically I want to expect ActionController::RoutingError: No route matches [GET] "/plates/claim/1".

  scenario 'they have to click the claim link' do
    create_plates
    sign_in_as_doctor
    visit claim_plate_path(@plates.first.id)
    ?????
  end

Answer 1

Try this

 scenario 'they have to click the claim link' do
    create_plates
    sign_in_as_doctor
    expect{visit claim_plate_path(@plates.first.id)}.to raise_error( ActionController::RoutingError)
  end
