#5998 ✓invalid

ActionView::TestCase does not honor default_url_options set in application_controller.rb

Reported by AdamTao | November 17th, 2010 @ 10:33 PM | in 3.0.5

Using Rails 3, I have a :scope in routes.rb:

scope "(/:locale)" do
  resources :products

In application_controller.rb I set the default :locale

def default_url_options(options={})
  {:locale => "en-US"}

In my views, this works when I test in my browser, but ActionView::TestCase tests fail

<%= link_to, product %>

While running a test, I see:

No route matches {:action=>"show", :controller=>"products", :locale=>#<Product id: ...>}

Here is a test that fails:

class ProductShowTest < ActionView::TestCase
  def test_render
    render "products/show", :product => => "WidgetA")
    assert_match /WidgetA/, rendered

    When unit testing views the controller is just a stub controller which inherits from ActionController::Base and not ApplicationController. You need to override this stub if you need special behaviour like default_url_options, e.g:

    # app/views/products/index.html.erb
    <%= link_to('Products', products_path) %>
    # test/unit/views/products_index_test.rb
    require 'test_helper'
    class ProductsIndexTest < ActionView::TestCase
      class ProductsController < TestController
        def default_url_options
          { :locale => 'de' }
      def setup
        @controller =
      def test_render
        render :template => "products/index"
        assert_match %r{href="/de/products"}, rendered

    Note that you have to define the controller in your test as using the real one will not have a test request and response.
