title: Executing thread groups separately in jmeter
body: <p>I have 2 thread groups in my test case. Group A should complete first before Group B starts to execute(at least I though this was the way it worked). </p>
  
  <p>Unfortunately they are firing at the same time and tests from both tread groups are executing, what can I do to prevent this from happening. Not to allow group B to start before group A is done executing?</p>
