title: Class methods: describe "#my_class_method" or describe "#self.my_class_method"?
body: <p>I try to have best-practice-conforming RSpec tests, and I know that when testing an instance method, one can do</p>
  
  <pre><code>describe "#my_instance_method" do ... end
  </code></pre>
  
  <p>But what about class methods? Should I add a <code>self.</code> to it in the description string?</p>
  
  <pre><code>describe "#self.my_class_method" do ... end
  </code></pre>
  
  <p>Thanks for your opinion!</p>
