I am in the process of upgrading from Rails 3 to 4. Whenever I run a test I always get two errors like this:
Capybara::Rails::TestCase#test_printer_url: ActionController::UrlGenerationError: No route matches {:action=>"test", :controller=>"printers"} missing required keys: [:id]
If I test all my controllers I get 2, if I just test one of my models I get the same 2. They are nothing to do with any test I have written myself, they seem to be tests Capybara is running on itself.
The problem seems to arise because I have a route for printers in my project, set up like this.
resources :printers do member do get :test end end
Okay, so just rename it to something to stop the name collision... If I rename "test" to "test_printer45745dc", or I change it from GET to POST it still fails! And if I have a second member line in there, I get four errors.
If I change it to a collection, I get a different error:
Capybara::Rails::TestCase#test_printers_url: ArgumentError: Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
What Capybara seems to do is to generate tests on the fly, based on the routes, and then generate errors however they are set up.
Why would it do that? What can I do about it?
I am using JRuby 1.7.4 on Windows, by the way
