Description

• batch session should not be gc-ed until application is finished *** FAILED *** (50 milliseconds)
  org.mockito.exceptions.misusing.UnfinishedStubbingException: Unfinished stubbing detected here:
  -> at org.apache.livy.sessions.SessionManagerSpec$$anonfun$1.org$apache$livy$sessions$SessionManagerSpec$$anonfun$$changeStateAndCheck$1(SessionManagerSpec.scala:129)
  E.g. thenReturn() may be missing.
  Examples of correct stubbing:
  when(mock.isOk()).thenReturn(true);
  when(mock.isOk()).thenThrow(exception);
  doThrow(exception).when(mock).someVoidMethod();
  Hints:
  1. missing thenReturn()
  2. you are trying to stub a final method, you naughty developer!
