title: How to generate automatic Rspec tests for existing scaffold
body: <p>I have an application on Ruby on Rails. All files have been modified from what the scaffold by itself generates. I want to include automatic testing with the Rspec gem, but I want it to generate all the automatic tests it normally does (since this is my first time working with rspec). </p>
  
  <p>I have seen that the usual way to do it is to install Rspec before generating the scaffolds (and when you generate the scaffold the tests are automatically generated), but since everything is already generated, how can I generate the tests only?</p>
  
  <p>I have got all the way to the <code>rails generate rspec:install</code> command, getting it ready for the test runs.</p>
  
  <p>How can I automatically generate the tests for an existing scaffold?</p>
