rspec users - Sep 2010 - Rspec and rails: Problems while testing libraries in the lib directory

I have some classes in the lib directory, and I want to test it. My
class which I want to test looks like:

class StatAggregation
  class << self
    def skills_rate(user_id)
      user_id = User.find_by_id(user_id)
      ...
    end
  end
end

I created spec:

require File.expand_path(File.dirname(__FILE__) + ''/../../
spec_helper'')

describe StatAggregation do
  fixtures [
    :users
  ]

  describe ''skills_rate method'' do
    it ''should work'' do
      @user_id = 1
      @user = mock_model(User)
 
User.should_receive(:find_by_id).with(@user_id).and_return(@user)
      ...
      StatAggregation.skills_rate(@user_id)
    end
  end
end

It works ok, but it doesn''t show where appeared error:

1)
ArgumentError in ''PxStatAggregation skills_rate method should
work''
wrong number of arguments (1 for 0)
script/spec:10:

Finished in 0.326331 seconds

How to get number of line where appeared error "wrong number of
arguments (1 for 0)"?

Use the -h flag on the [r]spec command (rspec for rspec-2, spec for
rspec-1) to learn about the command line options:

# rspec-1
spec -h

# rspec-2
rspec -h

In either case you''ll see a -b flag to get a full backtrace:

# rspec-1
spec spec -b

# rspec-2
rspec spec -b
