title: run JUnit 4 Groovy tests in order
body: <p>Currently I'm creating some Gebish tests. For easier understanding for myself I'm using the Class name as a case and the method as a step.</p>
  
  <p>Because of my idea I need a specific order to pass all tests. For that I put a-z in front of the files and class names.
  With <code>@FixMethodOrder(MethodSorters.NAME_ASCENDING)</code> I found a way to run the methods in an order. Now I'm stuck to run the classes in a specific order and I don't know how to fix it.</p>
  
  <p>When I'm running it in Intellij, it has no order.
  When I'm running it through the command line through gradle, it's running from a-z.
  When I'm running it through Jenkins, it has no order too.</p>
  
  <p>Now, how can I run the tests classes in an alphabetical order?</p>
