我几乎已经完成了我的滚烫的项目，它使用类型安全api而不是字段api。在整个项目设置中留给我的最后一个问题是整个烫伤作业本身的集成测试（我已经完成了类型安全外部操作模式的单元测试！）。这意味着运行整个作业并测试作业的各个接收器的输出。
然而，一些非常奇怪的事情正在发生。在我的

typedSink { scala.collection.mutable.Buffer[] => Unit }

似乎我的程序没有看到缓冲区，也没有对缓冲区做任何事情，所以集成测试总是通过，即使它不应该通过。以下是工作本身和测试，以帮助阐明正在发生的事情：

object MyJob {
  val inputArgPath = "input"
  val validOutputArgPath = "validOutput"
  val invalidOutputArgPath = "invalidOutput"
}

class MyJob(args: Args) extends Job(args) {

  import OperationWrappers._

  implicit lazy val uId: Some[UniqueID] = Some(UniqueID.getIDFor(flowDef))

  val inputPath: String = args(MyJob.inputArgPath)
  val validOutputPath: String = args(MyJob.validOutputArgPath)
  val invalidOutputPath: String = args(MyJob.invalidOutputArgPath)

  val eventInput: TypedPipe[(LongWritable, Text)] = this.mode match {
    case m: HadoopMode => TypedPipe.from(WritableSequenceFile[LongWritable, Text](inputPath))
    case _ => TypedPipe.from(TypedTsv[(LongWritable, Text)](inputPath))
  }

  def returnOutputPipe(outputString: String): FixedPathSource with TypedSink[(LongWritable, Text)] with TypedSource[(LongWritable, Text)] = {
    val eventOutput: FixedPathSource with TypedSink[(LongWritable, Text)] with TypedSource[(LongWritable, Text)] = this.mode match {
      case m: HadoopMode => WritableSequenceFile[LongWritable, Text](outputString)
      case _ => TypedTsv[(LongWritable, Text)](outputString)
    }
    eventOutput
  }

  val validatedEvents: TypedPipe[(LongWritable, Either[Text, Event])] = eventInput.convertJsonToEither.forceToDisk

  validatedEvents.removeInvalidTuples.removeEitherWrapper.write(returnOutputPipe(invalidOutputPath))
  validatedEvents.keepValidTuples.removeEitherWrapper.write(returnOutputPipe(validOutputPath))

  override protected def handleStats(statsData: CascadingStats) = {
    //This is code to handle counters.
  }
}

下面是集成测试：

class MyJobTest extends FlatSpec with Matchers {
  private val LOG = LoggerFactory.getLogger(classOf[MyJobTest])

  val validEvents: List[(LongWritable, Text)] = scala.io.Source.fromInputStream(getClass.getResourceAsStream("/validEvents.txt")).getLines().toList.map(s => {
    val eventText = new Text
    val typedFields = s.split(Constants.TAB)
    eventText.set(typedFields(1))
    (new LongWritable(typedFields(0).toLong), eventText)
  })

  "Integrate-Test: My Job" should "run test" in {

    LOG.info("Before Job Test starts.")
    JobTest(classOf[MyJob].getName)
      .arg(MyJob.inputArgPath, "input")
      .arg(MyJob.invalidOutputArgPath, "invalidOutput")
      .arg(MyJob.validOutputArgPath, "validOutput")
      .source(TypedTsv[(LongWritable, Text)]("input"), validEvents)
      .typedSink[(LongWritable, Text)](TypedTsv[(LongWritable, Text)]("invalidOutput")) {
      (buffer: mutable.Buffer[(LongWritable, Text)]) => {
        LOG.info("This is inside the buffer1.")
        buffer.size should equal(1000000)
      }
    }
      .typedSink[(LongWritable, Text)](TypedTsv[(LongWritable, Text)]("validOutput")) {
      (buffer: mutable.Buffer[(LongWritable, Text)]) => {
        LOG.info("This is inside the buffer2.")
        buffer.size should equal(1000000000)
      }
    }
      .run
      .finish
  }
}

最后，输出：

如您所见，记录器记录“作业测试开始前”的日志，但typedsink部分内部没有发生任何事情。这是令人沮丧的，因为我的代码看起来像我看到的所有其他代码，但它不工作。它应该没有通过测试，但一切都运行成功。此外，typedsink内部的记录器从不输出。最后，如果您查看输出，您会发现它正确地处理了计数器，因此它正在运行作业直至完成。我花了很多时间尝试新事物，但似乎什么都不管用。希望社区能够帮助我。谢谢！
