我在 sbt 中使用 ScalaTest 进行 ScalatraSuite 单元测试时遇到了一些问题。

我正在使用的版本：Scalatra：2.2.1 ScalaTest：1.9.1 ScalatraScalatest：2.2.1 Jetty：9.0.2.v20130417 Scala：2.10.1 SBT：0.12.3

我不得不扩展 ScalatraSuite 并覆盖 baseUrl 方法，因为 Jetty v9+ 我假设有一些代码更改，其中 getHost 和 getLocalPort 已被重构，因此作为临时解决方法，我同时使用它：

    trait TempScalatraSuite extends ScalatraSuite {

  override def baseUrl: String =
    server.getConnectors.headOption match {
      case Some(conn) =>
        val networkConn = conn.asInstanceOf[org.eclipse.jetty.server.NetworkConnector]
        val host = Option(networkConn.getHost) getOrElse "localhost"
        val port = networkConn.getLocalPort
        require(port > 0, "The detected local port is < 1, that's not allowed")
        "http://%s:%d".format(host, port)
      case None =>
        sys.error("can't calculate base URL: no connector")
    }
}

现在到了这一点，当在 sbt 中执行单元测试时，所有 scalatra 测试都失败了，这是我试图（通过 sbt）运行但没有运气的测试示例：

 class MyTestServiceHttpServiceSpec extends TempScalatraSuite with WordSpec {

  val log = LoggerFactory.getLogger(this.getClass.getName)

  addServlet(classOf[MyTestServiceHttpService], "/*")

  val contentType = Map("Content-Type" -> "application/json")

  "An invocation to /subscribeviaproxy" should {
    "yield a JSON result that contains a responseCode and a responseText when submitting a POST call" in {
      val jsonRequest = """{
                          "eventSource":"95100000",
                          "sourceNumber":"95100000",
                          "locale":"en_US"
                         }""""
      post("/subscribeviaproxy", jsonRequest.getBytes ,contentType) {
        log.info("responseBody is [{}]", body)
        status should equal (200)
        body should include ("responseCode")
        body should include ("responseMessage")
      }
    }
  }
}

SBT 总是失败并出现以下错误：

我可以看到码头服务器正在启动然后被关闭，但我真的不明白为什么。

先感谢您。

设法解决了这个问题，所有需要做的就是在 SBT 中设置一个选项来分叉 JVM 进行测试：

fork in Test := true,

之后的测试就像魅力一样。
