Description

There are some Junit api usage in scalatest, for example

 

  test("SPARK-31422: getMemoryStatus should not fail after BlockManagerMaster stops") {
    val bmm = new BlockManagerMaster(null, null, new SparkConf, true)
    assertTrue(bmm.getMemoryStatus.isEmpty)
  } 

`assertTrue` is junit api
