title: Custom failure messages in Rspec
body: <p>In my RSpec + Capybara tests, when I'm <code>expecting</code> something but the test fails, I'd like to have some custom messages.</p>
  
  <p>I achieved it with:</p>
  
  <pre><code>it "a test" do
   do_something
   expect(current_path).to eq('/some/path'), "expected path to be 'some_path' but fails"
  end
  </code></pre>
  
  <p>but what I'd like to have is ONLY my custome message, without the <strong>Failure/Error</strong> line from RSpec</p>

  <p>Is this possible?</p>
