title: Set up RSpec to test a gem (not Rails)
body: <p>It is pretty easy with the added generator of rspec-rails to set up RSpec for testing a Rails application. But how about adding RSpec for testing a gem in development?
  I am not using jeweler or such tools. I just used Bundler (<code>bundle gem my_gem</code>) to setup the structure for the new gem and edit the *.gemspec manually.
  I also added <code>s.add_development_dependency &quot;rspec&quot;, &quot;&gt;= 2.0.0&quot;</code> to gemspec and did a <code>bundle install</code>.</p>
  <p>Is there some nice tutorial what to do next to get RSpec working?</p>
