No route matches Anonymous controller problem

[g3d]

As i see, anonymous controller doesn`t work. I expect test custom 404 error handling, but have only errors:

rspec spec/controllers/errors_controller_spec.rb

No DRb server is running. Running in local process instead ...

I already looked to similar cases (like #573 or http://stackoverflow.com/questions/7027518/no-route-matches-rspecs-anonymous-controller) but it doesn`t helped me, so i writed this issue.

rspec (2.11.0, 2.10.0)
rspec-core (2.11.1, 2.10.1)

[andrewhavens]

I am running into a similar issue. Not sure how to test this type of scenario.

[alindeman]

Thanks for the detailed report. I'll see if I can figure out what's going on here soon; in the mean time, you might be able to test the coverage you want by testing this at a higher level using request specs.

[pcasaretto]

I think this is expected, see this:
c8523df
However, I believe this assumption is very limiting.
Maybe we can force the routing somehow?

[ku1ik]

I have similar issue and wondering what's the best way to handle this.

[vanstee]

Anonymus controllers only create resource routes. So routes like routing_error wont exist but stuff like index or show should work. Here's the spec that defines this functionality:

https://www.relishapp.com/rspec/rspec-rails/docs/controller-specs/anonymous-controller#anonymous-controllers-only-create-resource-routes

Does this resolve the issue you were seeing?

[alindeman]

It is possible to do something like this:

require "spec_helper"

describe ApplicationController do
  controller do
    def custom
      render :text => "custom!"
    end
  end

  describe "#custom" do
    before do
      routes.draw { get "custom" => "anonymous#custom" }
    end

    it "responds to GET" do
      get :custom
      expect(response.body).to eq "custom!"
    end
  end
end

YMMV as to whether it's a good idea for your app :) And @vanstee is correct in that we only draw the default resources routes for you.

[pcasaretto]

Very nice! Thanks @alindeman . That should be on the docs.
Quick question, will the drawn routes get rolled back, or do we have to do it on our own?

[alindeman]

The routes are rolled back automatically. If you'd like to submit a documentation update, I'd likely pull it in :)

[ngoral]

I got a problem with this too: usage of routes.draw in before block (not in it) causes all following tests to fail with No route matches ....
Am I missing something?

[henrik]

Another data point, without having delved deep into the issue:

If I add an index action (do def index; render text: "hi"; end) and then do get :index, everything works fine. If I try something else like get :show or get :foobar (having added a corresponding action), I get the route error.

index is also the only action I see in the doc examples (https://relishapp.com/rspec/rspec-rails/docs/controller-specs/anonymous-controller), so maybe it has some special magic.

EDIT: Ah, the docs go into this: https://relishapp.com/rspec/rspec-rails/docs/controller-specs/anonymous-controller#anonymous-controllers-only-create-resource-routes
