title: Using Cucumber with parallel_tests gives me a heap of undefined steps
body: <p>I'm trying to get parallel_tests working with my cucumber features as it allows me to run my tests much faster.</p>

  <p>Problem is that when I run my features this way I get a heap of undefined steps. I've seen this problem mentioned as a closed issue here:</p>

  <p>With phuong-nguyen he suggests adding features/step_definitions features/support to my bundle exec command. I've tried this every which way, how do I include these two directories in my bundle exec command?</p>
  
  <p>Here is what I've tried so far:</p>
  
  <pre><code>$ bundle exec rake --require features/step_definitions --require features/support parallel:features
  $ bundle exec features/step_definitions features/support rake parallel:features   
  $ bundle exec rake parallel:features features/step_definitions features/support
  </code></pre>
  
  <p>Update:</p>
  
  <p>After updating parallel_tests to 0.6.1 the following command still has the same issue:</p>
  
  <pre><code>$ bundle exec rake parallel:features features/step_definitions features/support
  </code></pre>
  
  <p>Some features pass whilst others still cannot find the steps</p>
