How to terminate session in Selenium Grid? My problem is that if my test fail hub still keep session for this test and I can't run another test (it run but fail because can't get free node, because it is registered in hub). I have found this How to kill thread in a Selenium Grid node and there is an answer to use DELETE /session/:sessionId but it didn't work for me. Documentation on Selenium Grid or Extras is very pure, maybe some one have similar issue and know how to resole it?
