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:

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
