Can't get controller test working with RSpec 2 and edge Rails 3

Question

Not sure if this is a Rails 3 issue or an RSpec 2 issue, but I can't seem to get a standard controller test working - it seems that the 'get' method can't be found.

I have a controller test that looks like this (named discrepancies_controller_spec.rb in spec/controllers directory):

require 'spec_helper'

describe DiscrepanciesController do
  before :each do
    Discrepancy.delete_all
  end

  it "resolves a discrepancy" do
 discrepancy = Discrepancy.create(:my_number=>"12345", :status=>"Open")

 get :resolve, :id => discrepancy.id

 retrieved_discrepancy = Discrepancy.find_by_my_number("12345")
 retrieved_discrepancy.status.should == "Resolved"
  end
end

(Yes, I'm aware of the security implications of modifying data with an HTTP/GET - that's a separate issue...)

When I run it with rake, I get the following error:

1) DiscrepanciesController resolves a discrepanc
    Failure/Error: Unable to find C to read failed line
    undefined method `get' for #<RSpec::Core::ExampleGroup::Nested_1:0xc9170d0 @__memoized={}>
    # ./spec/controllers/discrepancies_controller_spec.rb:38 (ignore the line number, commented out code was removed from the sample)
    # C:/Users/Patrick_Gannon/.bundle/ruby/1.8/bundler/gems/rails-16a5e918a06649ffac24fd5873b875daf66212ad-master/activesupport/lib/active_support/dependencies.rb:212:in `inject'
    # C:/Ruby187/bin/rake:19:in `load'
    # C:/Ruby187/bin/rake:19

I can manage to test the controller action by instantiating the controller myself and calling the controller action directly, and it works, but its ugly because I have to mock out things like respond_to and params.

Other pertinent information: I am running Windows 7 32-bit, Ruby 1.8.7 (2010-01-10 patchlevel 249) [i386-wingw32], edge Rails 3 and MongoDB/MongoMapper. Here is my list of installed gems (via 'bundle gem' - all my installed gems were installed by Bundler)

I also added a puts statement in the test to show what methods are available in the test fixture ((methods - Object.methods).sort.inspect), and "get" is not in the list. Here is what is in the list:

Answer 1

Got an answer to this on the RSpec mailing list from David Chelimsky, as follows:

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
