BrowserStack – Node.js并发testing
我一直在研究如何使用BrowserStack专门为Node.js中的可伸缩testing创build一个合理的结构。
请在这里查看源代码：
https://gist.github.com/Palgie/10886008 试图closures会话或退出驱动程序时遇到问题，因此在运行并发testing时，它会经常告诉我，我的最大会话正在使用中（请参阅下文）。
这感觉就像一个竞赛条件，但它可能是一件非常明显的事情。

在我的参考资料中，据我所知，它应该执行会话，但不会觉得这样。
test.after(function() { console.log('Stopping test'); driver.quit(); });
据我了解，在浏览器运行所有的摩卡testing或webdrivertesting后，它将终止驱动程序，然后它会在before方法中初始化一个新的实例。
任何帮助，将不胜感激！
干杯
您可以使用selenium runner并行运行testing。 使用Selenium Runner在BrowserStack上并行运行testing的示例在以下文档中给出： https ： //www.browserstack.com/automate/node 。
此外，如果selenium跑者不能满足您的需求，您可以请分享您的需求（哪些特定的框架或库代码，你想并行运行），以便我们可以看看这个问题
