Javascript BrowserStack-Node.js并发测试

我一直在研究如何使用BrowserStack为Node.js中的可伸缩测试创建合理的结构

请在此处查看来源：

我在尝试关闭会话或退出驱动程序时遇到问题，因此在运行并发测试时，它会经常告诉我正在使用max会话（请参见下文）

这感觉像是一种比赛状态，但可能是非常明显的

  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.

据我所知，在浏览器中运行所有mocha测试或webdriver测试之后，它将终止驱动程序，然后在before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。以下文档中给出了使用selenium runner在BrowserStack上并行运行测试的示例：

此外，如果selenium runner不能满足您的需求，请您分享您的需求（您希望并行运行哪个特定的框架或库代码），以便我们可以关注这个问题

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