Testing a redirect outside of a controller

I have a helper module with a method that fires off redirect_to if the current user does not have permission to visit a web page.

I am getting a NoMethodError error when running the tests, since the helper does not actually have a redirect_to method. I have tried stubbing out redirect_to like this:

it "redirects the user to the user's langing page if the user doesn't have permission" do
  allow(helper).to receive(:current_or_guest_user) { test_user }
  expect(helper).to receive(:redirect_to)
  helper.require_permission :view_admins
end

but I get a long long error that the helper does not implement redirect_to.

Is there a way to stub out this method?

You could create an anonymous controller in your spec and include your module in it. When you've got that, you can test it like a normal controller action/method. So, add something along the lines of this to your spec:

controller(YourController) do
  include YourModule

  def index
    render text: 'body'
  end
end

I don't know whether your method is a before_action or not, but it seems like it is since you're testing whether the user has the required view_admins permission.

So, when the user has the required permission, your spec should be something like this:

context 'when the user has the required permission' do
  before do
    # make sure the user has the required permission
  end

  it 'the user will see the rendered text' do
    get :index
    expect(response.body).to eq 'body'
  end
end

And when the user doesn't have the required permission they'll be redirected to the path you've defined. So, something like this:

context 'when the user does NOT have the required permission' do
  before do
    # make sure the user does NOT have the required permission
  end

  it 'the user will be redirected to the specified path' do
    get :index
    expect(controller).to redirect_to your_specified_path
  end
end
