title: Test parallelism with IntelliJ and TestNG
body: <p>I'm attempting to run some TestNG tests in parallel but don't have access to a testng.xml as IntelliJ builds it on the fly.  I've tried adding parameters such as 'parallel=methods' to the run configuration but this doesn't appear to be making any difference.</p>
  
  <p>How can I make TestNG run in parallel from IntelliJ without resorting to having to build my own testng.xml file?</p>
