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

#5998

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

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

In application_controller.rb I set the default :locale

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

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

<%= link_to product.name, 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 => Product.new(:name => "WidgetA")
    assert_match /WidgetA/, rendered
  end
end

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' }
    end
  end

  def setup
    @controller = ProductsController.new
  end

  def test_render
    render :template => "products/index"
    assert_match %r{href="/de/products"}, rendered
  end
end

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