There was a problem hiding this comment.
Based on our assumption everywhere else, that is Cancel comes before StartTestRun.
If Cancel comes, it will result in a HandleTestRunComplete, where we have a baseTestRunEventsHandler which only gets set if Start was called, else it could also potentially cause null reference.
