With Rails 3.2 LTS your RSpec 2 controller specs might fail with an error like this:

CopyNoMethodError:
  undefined method `[]' for nil:NilClass

Fix

To fix this, use our compatibility fork of rspec-rails 2.14 Show archive.org snapshot .

You can switch to the fork by updating your Gemfile:

Copygem 'rspec-rails', :git => 'https://github.com/makandra/rspec-rails.git', :branch => '2-14-lts'

Now run bundle update rspec-rails.
