title: How to check if a method exists using Rspec?
body: <p>I want to write a nice clean check whether a method exists or not:</p>
  
  <pre><code>expect(subscriber.respond_to?(:fake_method)).to be(true)    &lt;-- This fails (as expected)
  
  expect(subscriber).respond_to?(:fake_method)                &lt;-- This passes, why?
  </code></pre>
  
  <p>The fake_method does not exist, but when I use the second convention, my test passes.</p>
  
  <p>Any ideas?</p>
