Java 使用负载性能列表进行Selenium测试

我正在尝试使用我的单元测试在浏览器上进行“负载”测试。由于各种原因，我们看到浏览器端的性能下降，因为我们严重依赖打印对话框

我通过ScalaTest进行了以下单元测试：

class LoadPrePaidSpec extends FlatSpec with Matchers with Chrome with Eventually {

implicit override val patienceConfig =
    PatienceConfig(timeout = scaled(Span(40, Seconds)), interval = scaled(Span(100, Millis)))
def build(csvLine:String):TestCSVHolder ={
    val split = csvLine.split(",")
    TestCSVHolder(memberId = split(0), preSaleCode = split(1),
      prePaidCode = split(2), lastName = split(3), firstName = split(4), badgeName = split(5))
  }

  def memberHelper(member: TestCSVHolder): Unit = {
    //insert member id via prepaid code
    textField("member_id").value = member.prePaidCode
    //fire keyup event
    executeScript("var eventToFire=jQuery.Event(\"keyup\");eventToFire.keyCode=221;eventToFire.which=221;" +
      "$(\"#member_id\").trigger(eventToFire)")
    eventually {
      val eles = webDriver.findElements(By.xpath(s"//*[contains(@id, '${member.memberId}')]"))
      eles.get(0).getTagName
      //We remove the head element because it just says Prep For Print
      val tdEles = (eles.get(0).findElements(By.tagName("td")).toList.tail)
      tdEles(0).getText() should be(member.lastName)
      tdEles(1).getText() should be(member.firstName)
      tdEles(2).getText() should be(member.badgeName)
    }
  }

  "Scanning an ID" should "look up the member" in {
    val member = new TestCSVHolder("100001", "ABCD", "[-100001-ABCD]", "John", "Doe", "JohnDoe")

    go to (url)
    //login
    textField("user_name").value = "mrkaiser"
    webDriver.findElementById("credentials").sendKeys("somepassword")
    click on ("btnLogin")
    //click to pre-paid
    click on linkText("Pre-Paid")
    memberHelper())
    webDriver.quit()
  }
}

但是，当我尝试使用foreach遍历元素列表并传入memberHelper时，在大约5个元素的列表之后，我得到以下堆栈跟踪：

The code passed to eventually never returned normally. Attempted 369 times over 40.110734904 seconds. Last failure message: Index: 0, Size: 0.

我的最终目标是从一个文件中实际测试20K范围内的元素，但在我能得到一个像这样的小列表之前，我很为难

---

我在Scala 2.11.6、Scala测试2.2.0和selenium 2.35.0上使用chromedriver和am

看起来你用lambda打了一个“最终”的电话-试着在那里输入一些日志，看看369次尝试失败的原因。啊，我应该澄清一下，当发出一次运行时，我没有发现异常。当我使用列表并多次运行它时，会出现错误。我试图在浏览器端做一个压力测试。我真正想做的是尝试看看浏览器是否有内存泄漏，以及它如何处理打印。我的团队已经看到IE在打印对话框的负载下（我们每天在每台机器上打印5-6K标签），由于我们正在转向Chrome，我们希望自动化一个测试，让我们检查Chrome是否能够处理负载。
