title: simpler way to test my simple Rack app?
body: <p>i have a Rack app like this:</p>
  
  <pre><code>app = Rack::Builder.new do
  
      map '/' do
          # ...
      end
  
      map '/edit' do
          # ...
      end
  
  end.to_app
  </code></pre>
  
  <p>How would i test it without long-tail installation/setup/learn process.</p>
  
  <p>RSpec and minitest are really great, but i do not really want to learn nor setup them.</p>
  
  <p>Is there something i cat just plug in and write/run tests right away in plain Ruby?</p>
  
  <p>I want to write tests as simple as i wrote the app above, without advanced techniques and gotchas.</p>
  
  <p>In KISS I Trust!</p>
