Why is Rspec saying "Failure/Error: Unable to find matching line from backtrace"?

Question

I'm following the rails tutorial here: http://railstutorial.org/chapters/filling-in-the-layout#top

When I run "rspec spec/", I get a bunch of errors that look like this:

1) LayoutLinks should have a Home page at '/'     Failure/Error: Unable to find matching line from backtrace     stack level too deep     # C:/Ruby19/lib/ruby/1.9.1/forwardable.rb:185  2) LayoutLinks should have a Contact page at '/contact'     Failure/Error: Unable to find matching line from backtrace     stack level too deep     # C:/Ruby19/lib/ruby/1.9.1/forwardable.rb:185 

But when I go in my web browser to localhost:3000/ and localhost:3000/contact, the pages are there and the correct titles are there. Here is my myrailsroot\spec\requests\layout_links_spec.rb file:

require 'spec_helper'  describe "LayoutLinks" do    it "should have a Home page at '/'" do     get '/'     response.should have_selector('title', :content => "Home")   end    it "should have a Contact page at '/contact'" do     get '/contact'     response.should have_selector('title', :content => "Contact")   end    it "should have an About page at '/about'" do     get '/about'     response.should have_selector('title', :content => "About")   end    it "should have a Help page at '/help'" do     get '/help'     response.should have_selector('title', :content => "Help")   end    it "should have a signup page at '/signup'" do     get '/signup'     response.should have_selector('title', :content => "Sign up")   end  end 

Any ideas would be great, thanks

Answer 1

This is due to a bug in RSpec 2.0.0.beta.19. If you use 2.0.0.beta.18 as the tutorial suggests, it will work fine. Just change whatever version you have in your Gemfile to beta 18, bundle install and run the tests again.

Here's the relevant parts from my Gemfile.

group :development do   gem 'rspec-rails', '2.0.0.beta.18' end  group :test do   gem 'rspec-rails', '2.0.0.beta.18'   gem 'spork', '0.8.4' end 

Also note that Spork can also cause problems like this from time to time. If you get inexplicable test failures, especially if you just added new controllers or actions, go give spork a kick. Hit Ctrl-C and run the spork server again.

my gemfile looked like this and it works

group :test do      gem 'rspec-rails'     gem 'webrat', '0.7.1' end 

where rspec-rails (2.1.0)

however following doesn't:

group :test do      gem 'rspec-rails'     gem 'webrat', '0.7.2' end 

So I think it is webrat plays up.
