I'm using RSpec for testing and when I left work Friday afternoon, my tests were passing. But when I went home and synced my repository, the tests failed on my laptop. Now back at work, the tests are failing still. Don't believe its my code since running rspec by itself returns an error and spork won't even start up. When I try to start Spork, I get the following error message:
Using RSpec
Loading Spork.prefork block...

Anyone know what could be causing this?
I ran into this problem. In the spec_helper.rb try replacing:
require "rails"
with
require "rails/all"
Worked in my situation.
You need to initialize environment, add this line to spec_helper.rb:
require File.expand_path("../../config/environment", __FILE__)
You may encounter this issue if you're trying to use rspec-rails in a non-rails project. In that case using require "rails/all" is not an option because it'd require ActiveRecord stuff leaving you with:
ActiveRecord::ConnectionNotEstablished: No connection pool with 'primary' found.
Instead you can fix this issue with:
require "action_controller/railtie"
If it's not a Rails app and you don't want to include all of Rails, add this to your spec_helper.rb:
require 'action_view'
