I've created a Rails Engine in the normal fashion, installed RSpec, and generated a scaffold for a model, but I can't get any routing specs to pass.
Here's one example:
describe Licensing::LicensesController do
it 'routes to #index' do
get('/licensing/licenses').should route_to('licensing/licenses#index')
end
end
I'm running the examples in the dummy app like this:
$ cd spec/dummy
$ rake spec
/Users/brandan/.rvm/rubies/ruby-1.9.3-p194/bin/ruby -S rspec ../routing/licensing/licenses_routing_spec.rb
F
Failures:
1) Licensing::LicensesController routes to #index
Failure/Error: get('/licensing/licenses').should route_to('licensing/licenses#index')
No route matches "/licensing/licenses"
# /Users/brandan/repos/licensing/spec/routing/licensing/licenses_routing_spec.rb:5:in `block (2 levels) in <top (required)>'
Finished in 0.04345 seconds
1 example, 1 failure
The engine is mounted correctly in the dummy app:
# spec/dummy/config/routes.rb
Rails.application.routes.draw do
mount Licensing::Engine => "/licensing"
end
And I can go into the dummy app and fire up the console and get that route just fine:
1.9.3p194 :001 > app.get('/licensing/licenses')
Licensing::License Load (0.3ms) SELECT "licensing_licenses".* FROM "licensing_licenses"
200
1.9.3p194 :002 > app.response.body
"<!DOCTYPE html>..."
There's some discrepancy between the dummy app and RSpec, and I can't figure out what it is. I've found several articles that claim to solve this problem, but none of them have helped, and several of them are specific to Rails 3.1:
Has anybody solved this problem in Rails 3.2/RSpec 2.10?

Update (2013-10-31)
RSpec 2.14 now fully supports engine routes:
module MyEngine
describe ExampleController do
routes { MyEngine::Engine.routes }
end
end
Add it to all routing specs:
# spec/spec_helper.rb
config.include Module.new {
def self.included(base)
base.routes { Reportr::Engine.routes }
end
}, type: :routing
The best solution I've been able to find so far is explicitly setting the route set that will be used during the tests:
RSpec.configure do |config|
config.before(:each, type: :controller) { @routes = Licensing::Engine.routes }
config.before(:each, type: :routing) { @routes = Licensing::Engine.routes }
end
Then I had to rewrite my routing examples to omit the namespace:
it 'routes to #index' do
get('/licenses').should route_to('licensing/licenses#index')
end
This seems like a bit of a hack, but it does make sense. I'm not testing whether Rails is able to mount an engine at a particular path. I'm only testing that my engine has correctly set up its own routes. Still, I'd rather not have to overwrite an instance variable to make it happen.
Here are another couple of good threads on this topic:
