title: How to kill phantomjs processes running in background after the tests are completed
body: <p>After I run the phatomjs/java integration tests on the build server , the phantomjs processes still keep running in the background and have to be killed manually.</p>
  
  <p>Is there a way to do this in the java code? I am already using driver.quit() in the test cleanup part. Is there anything else also to be included?</p>
