title: How to rerun failed test cases in the same test run(test run was launched by TFS2015 vNext Run Functional Test task)
body: <p>We are trying to migrate our coded UI tests from MTM to TFS2015 vNext web based test management. </p>
  
  <p>Before in MTM, after a test run is done, you can right click and rerun failed test cases. 
  But in the test run that launched by "run functional test" task in vNext build, there is no such option (you can not even see the test run in MTM). </p>
  
  <p>I would like still be able to select the failed test case and rerun it in the same test environment, and update the test result in the same test run after the rerun finish. </p>
  
  <p>Any way to achieve this?</p>
  
  <p>Thanks,
  Angel</p>
