grammar of 'get' is incorrect here. Try something like:
RunPendingTasksUntilCallback
RunPendingTasksUntilFirstCallback
RunPendingTasksUntilSuccessCallback
RunPendingTasksUntilErrorCallback

And document in this header that it runs tasks until the first callback that the
test fixture tracks.

Done.

   void FinishPendingTasks();
