title: Ordering unit test using XCTest in Xcode 6
body: <p>I would like to know if there is any way to tell Xcode to run unit tests in a specified order. I mean not in a same XCTestCase class file, but between all the class file.</p>
  
  <p><img src="https://i.stack.imgur.com/4zLg3.png" alt="enter image description here"></p>
  
  <p>For example I want to run the SitchozrSDKSessionTest before running SitchozrSDKMessageTest.</p>
  
  <p>I looked over few threads on stack or on Apple documentation and I haven't found something helpful.</p>
  
  <p>Thanks for your help.</p>
