title: Call database seeder from a subfolder
body: <p>I want to create a set of database seed classes specifically for adding data for test cases I'm writing. </p>
  
  <p>My plan was to put them in the folder:</p>
  
  <pre><code>app/database/seeds/testData/
  </code></pre>
  
  <p>and then call the seeder via the command:</p>
  
  <pre><code>php artisan db:seed --class="testData/myTestSeeder"
  </code></pre>
  
  <p>But I get a "class does not exist" error. </p>
  
  <p>Is it possible to call database seeders that live in a subfolder in seeds? I don't see an explicit "yes" in the docs, but I don't see an explicit "no" either. </p>
