title: Rails: rake db:test:prepare Vs rake test:prepare
body: <p>AS the guides, the command used to prepare test database is</p>
  
  <pre><code>bundle exec rake db:test:prepare
  </code></pre>
  
  <p>However, I have found that following command also works &amp; created the test db for me.</p>
  
  <pre><code>bundle exec rake test:prepare
  </code></pre>
  
  <p>Wanted to know if this is a valid command, if yes. Where can I find the documentation. </p>
  
  <p>tested on <code>rails 3.2.8</code></p>
