BrowserStack - Node.js并发测试

Question

我一直在寻找在Node.js中为可伸缩测试创建合理结构的方法，特别是使用BrowserStack。

请在此处查看源代码：

https://gist.github.com/Palgie/10886008

在尝试关闭会话或退出驱动程序时，我遇到了一个问题，因此当运行并发测试时，它会经常告诉我我的最大会话数正在使用中(见下文)。

这看起来像是一种竞争状况，但它可能是非常明显的事情。

  Now testing Chrome - 22.0
  Now testing IE - 10.0
  ․․․․
  Stopping test
  Stopping test
  ․

    4 passing (14s)
    1 failing

    1)  "after all" hook:
       Error: This driver instance does not have a valid session ID (did you call WebDriver.quit()?) and may no longer be used.

        at Timer.listOnTimeout [as ontimeout] (timers.js:110:15)

在源代码中，我引用了它，据我所知，它应该执行会话，但感觉不像是。

test.after(function() {
  console.log('Stopping test');
  driver.quit();
});

据我所知，在浏览器中运行所有mocha测试或webdriver测试之后，它将终止driver，然后在之前的方法中初始化一个新实例。

任何帮助都将不胜感激！

干杯

您可以使用selenium-runner并行运行测试。以下文档提供了使用selenium-runner在BrowserStack上并行运行测试的示例：https://www.browserstack.com/automate/node。

此外，如果selenium-runner不能满足您的需求，您是否可以分享您的需求(您希望并行运行哪个特定的框架或库代码)，以便我们可以查看此问题
