> DAGSchedulerSuite exists many test case(e.g. trivial job failure | run shuffle with map stage failure) contains the pattern of failed + assert, such as:
> {code:java}
>   test("trivial job failure") {
>     submit(new MyRDD(sc, 1, Nil), Array(0))
>     failed(taskSets(0), "some failure")
>     assert(failure.getMessage === "Job aborted due to stage failure: some failure")
>     assert(sparkListener.failedStages === Seq(0))
>     assertDataStructuresEmpty()
>   }
> {code}
> We should extract the general method like failedAndCheck(taskSet: TaskSet, message: String, predicate)
