Question

运行sbt测试，出现以下错误消息：

如您所见，所有测试均通过。怎么了？提示，我正在使用Intellij。

更新

这是代码：

import atto._
import Atto._
import cats._
import cats.implicits._

sealed trait PcpPair

case class PcpHead(key: String, value: String) extends PcpPair

case class PcpFieldValue(field: String, value: String) extends PcpPair

case class Pcp(head: List[PcpHead], fv: List[PcpFieldValue], body: String)


object PcpProtocol {

  implicit val pcpProtocol: Protocol[Pcp] = new Protocol[Pcp] {
    override def encode(text: String): ProtocolResult[Pcp] =
      doc
        .parseOnly(text)
        .either
        .flatMap { t =>
          isValidPcp(t._1) match {
            case true => Right(t)
            case false => Left("It is not a valid PCP protocol.")
          }
        }
        .map(t => Pcp(filterPcpHead(t._1), filterFieldValue(t._1), t._2))

    override def decode(msg: Pcp): String = ???
  }

  private val PcpValidity = "pcp-"

  private val key = stringOf(letter | char('-'))
  private val value = stringOf(notChar('\n'))
  private val kv = (key <~ char(':')) ~ value
  private val kvs = sepBy(kv, char('\n'))
  private val doc = (kvs <~ string("\n\n")) ~ takeText


  private val isValidPcp: List[(String, String)] => Boolean = textList =>
    textList
      .map(kv => kv._1.startsWith(PcpValidity))
      .foldLeft(true)(_ || _)

  private val filterPcpHead: List[(String, String)] => List[PcpHead] = textList =>
    textList
      .filter(text => text._1.contains(PcpValidity))
      .map(text => PcpHead(text._1, text._2))

  private val filterFieldValue: List[(String, String)] => List[PcpFieldValue] = textList =>
    textList
      .filter(text => !text._1.contains(PcpValidity))
      .map(text => PcpFieldValue(text._1, text._2))

  private val decodeHead: List[PcpHead] => String = heads =>
    heads.foldLeft("") { (acc, value) =>
      acc |+| value.key |+| ":" |+| value.value |+| "\n"
    }

  private val decodePair: List[PcpPair] => ((String, PcpPair) => String) => String = pcpList => fnPcp =>
    pcpList.foldLeft("")(fnPcp)

}

这是测试：

class PcpParserSpec extends FunSpec with Matchers {

  val valid =
    """pcp-action:MESSAGE
      |pcp-channel:apc\:///
      |pcp-body-type:text
      |PUBLICKEY:THISPK
      |TOPIC:SEND
      |
      |Hello Foo""".stripMargin

  describe("Receive message from SAP server") {


    it("should contains pcp-channel:apc") {
      Protocol.encode(valid) should be('right)
    }

    it("should be separated by head and body") {
      Protocol.encode(valid) match {
        case Right(value) => assert(value.head.length > 0)
        case Left(text) => assert(text.length > 0)
      }
    }

    describe("The body of the message") {

      it("should contains Hello Foo") {

        Protocol.encode(valid) match {
          case Right(value) => assert(value.body == "Hello Foo")
          case Left(text) => assert(text.length > 0)
        }
      }
    }

  }

  describe("Send message to SAP") {

    it("should encode appropriate PCP protocol") {

    }

  }

}

您可能会发现target/streams/test/test/\$global/streams/succeeded_tests（在您的项目目录中）出现乱码。（我的是一团乱码。）

您应该得到类似的东西

#Successful Tests
#Thu Apr 04 07:54:33 NZDT 2019
MyTest=1554317673393

它试图读取的数字在=之后。

（对我而言）令人困惑的一点是它正在输出摘要-解析失败时我的并没有。

在运行以下操作之前，可以在这里的评论中分享succeeded_tests（上）的（某些）内容吗（我很好奇看到这些失败）。 / p>

sbt clean test应该可以解决您的问题...
