Testing error pages in Rails with Rspec + Capybara

Question

In Rails 3.2.9 I have custom error pages defines like this:

# application.rb config.exceptions_app = self.routes  # routes.rb match '/404' => 'errors#not_found' 

Which works like expected. When I set config.consider_all_requests_local = false in development.rb I get the not_found view when visiting /foo

But how do I test this with Rspec + Capybara?

I've tried this:

# /spec/features/not_found_spec.rb require 'spec_helper' describe 'not found page' do   it 'should respond with 404 page' do     visit '/foo'     page.should have_content('not found')   end end 

When I run this spec I get:

1) not found page should respond with 404 page   Failure/Error: visit '/foo'   ActionController::RoutingError:     No route matches [GET] "/foo" 

How can I test this?

Edit:

Forgot to mention: I've set config.consider_all_requests_local = false in test.rb

Answer 1

The problematic setting in the test.rb is not only the

consider_all_requests_local = false 

but also

config.action_dispatch.show_exceptions = true 

If you set this you should be able to test the error. I was not able to use it in an around filter.

Have a look for http://agileleague.com/blog/rails-3-2-custom-error-pages-the-exceptions_app-and-testing-with-capybara/

Answer 2

the config.consider_all_requests_local = false setting would need to be set in config/environments/test.rb in the same way you have done for your development one.

If you don't want to do this for all tests, perhaps an rspec around filter would be useful to set the state before the test and restore afterwards like so:

# /spec/features/not_found_spec.rb require 'spec_helper' describe 'not found page' do   around :each do |example|      Rails.application.config.consider_all_requests_local = false      example.run      Rails.application.config.consider_all_requests_local = true   end    it 'should respond with 404 page' do     visit '/foo'     page.should have_content('not found')   end end
