I'm surprised this is the first time this has come up with rspec-2, but here we are :)

This is a path-separator bug that I'll resolve in the next release. For now, you can do this in your controller specs:

describe DiscrepanciesController do
  include RSpec::Rails::ControllerExampleGroup

That should work fine.

If you want to do a more global workaround, add this to your spec_helper config:

RSpec.configure do |c|
  c.include RSpec::Rails::ControllerExampleGroup, :example_group => { :file_path => /\bspec[\\\/]controllers[\\\/]/ }
end

HTH,
David
