title: How to develop Gems?
body: <p>I would like to write my own gem that helps me in my rails apps. It will also inculde some controllers that deliver html. So i need to test that in a browser (html/css/js). </p>
  
  <p>Whats the best practice for that? </p>
  
  <p>Now im using the echoe gem to build my gem (are there any better gems?).
  rake install
  switch to other tab
  stop the rails app
  start the rails app (so it has loaded the gem)
  and then testing it, in a browser with good old refresh.</p>
  
  <p>This is no fun. Can i do it more efficient somehow? Is it insane not to write tests for the ruby files?</p>
