scala play框架中默认IntegrationSpec中定义的端口在哪里？

scala play框架的默认集成规范如下所示：

class IntegrationSpec extends PlaySpec with OneServerPerTest with OneBrowserPerTest with HtmlUnitFactory {

  "Application" should {

    "work from within a browser" in {

      go to ("http://localhost:" + port)

      pageSource must include ("Your new application is ready.")
    }
  }
}

单击

端口

变量打开

OneServerPerTest.scala

文件：

  /**
   * The port used by the `TestServer`.  By default this will be set to the result returned from
   * `Helpers.testServerPort`. You can override this to provide a different port number.
   */
  lazy val port: Int = Helpers.testServerPort

单击Helpers.testServerPort将导致：

  /**
   * The port to use for a test server. Defaults to 19001. May be configured using the system property
   * testserver.port
   */
  lazy val testServerPort = Option(System.getProperty("testserver.port")).map(_.toInt).getOrElse(19001)

---

搜索

testserver.port

不会返回变量。当默认端口为9000且其中定义了

testserver.port

时，测试如何成功？

使用此端口启动

testserver

，如下所示。9000端口是开发模式的默认端口，而不是所有测试模式。如果在用于启动测试的命令中未设置

testserver.port

属性，则将使用默认属性（19001）
