Error `comparison of Symbol with Module failed` after upgrading to Rspec 3

rspec, rspec-rails, ruby-on-rails

Solution

You can't use symbols after `describe` anymore. You need to replace

describe :index do

with

describe 'index' do

You are however able to use symbols as tags, for example...

describe 'index', :awesome do
  ...
end

Now when running the tests you can target only tests with a certain tag.

$ rspec --tag awesome

Problem

I just upgraded from Rspec 2.99 to Rspec 3 and am getting the following error for some of my tests. ``` Failure/Error: Unable to find matching line from backtrace ArgumentError: comparison of Symbol with Module failed ``` I have the following controller test ``` require 'spec_helper' describe PeopleController, type: :controller do subject { response } describe :index do before { get :index } it { should_not be_success } it { should have_http_status '401' } end end ``` Any idea what might be causing the error?
