rspec users - Aug 2011 - inheriting test cases vs. mixing them in

I''ve come across an interesting blog post showing how to inherit
tests:

http://benbiddington.wordpress.com/2010/11/06/rspec-common-base-specs/

How does it stack against the usual mixing/shared_examples_for,
beautifully described in

http://blog.davidchelimsky.net/2010/11/07/specifying-mixins-with-shared-example-groups-in-rspec-2/

I.e., what are the cases where you''d do inheritance vs
shared_examples_for?

Cheers,
Alexy

I see no use case for class inheritance in RSpec. If you need to include
some methods in a spec, use the `include` config option:

module MySpecMethods
  def foo
  end
end

RSpec.configure do |config|
  config.include MySpecMethods

  # to restrict to controllers, for example
  config.include MySpecMethods, :type => :controller
end
