I'm creating a gem that will generate a controller for the Rails app that will use it. It's been a trial and error process for me when trying to test a controller. When testing models, it's been pretty easy, but when testing controllers, ActionController::TestUnit is not included (as described here). I've tried requiring it, and all similar sounding stuff in Rails but it hasn't worked.

What would I need to require in the spec_helper to get the test to work?

Thanks!

  • I've brought up this question in rspec-users mailing list, and Aslak Hellesoy said that generally, if you're testing a Rails thing, it's easier to compile the gem, use it in a Rails app and write those tests in the Rails app. While it definitely sounds easier, it feels like it's very broken apart. It will make it brittle when I put this gem out there in the wild. Commented Apr 6, 2010 at 15:27

Here's an example of a working standalone Test::Unit test with a simple controller under test included.. Maybe there's some parts here that you need to transfer over to your rspec code.

require 'rubygems' require 'test/unit' require 'active_support' require 'active_support/test_case' require 'action_controller' require 'action_controller/test_process' class UnderTestController < ActionController::Base def index render :text => 'OK' end end ActionController::Routing::Routes.draw {|map| map.resources :under_test } class MyTest < ActionController::TestCase def setup @controller = UnderTestController.new @request = ActionController::TestRequest.new @response = ActionController::TestResponse.new end test "should succeed" do get :index assert_response :success end end

Thanks I will try this later today and post up how it goes.
It seems the fundamental difference is that I don't think you can make your test class a subclass of ActionController::TestCase in rspec. In rspec I believe it's automatically inferred based on the describe block. eg. describe SampleController, "on GET index" will look for the SampleController in app/controllers. I hope I'm wrong and this can be overridden!
