How to load a spec_helper.rb automatically in RSpec 2

In RSpec 2, the /spec folder is always automatically on your load path. This means that all you need is:

require 'spec_helper'

at the top of your spec files. This will always load /spec/spec_helper.rb, and is the minimum you'll be able to get away with.

This means you don't need a horrid approach such as:

require File.join(File.dirname(File.dirname(__FILE__)), 'spec_helper.rb')

(which needs to be updated for different nesting levels).

Also you can add to your .rspec file the option: --require spec_helper, which will require this file in each spec file, without the manual require statement at the top.

The --require spec_helper line is automatically added to the .rspec file for RSpec 3.0 when you do rspec --init.
