我正在使用量角器来运行测试。它以随机顺序失败，但并非总是如此，但是从6起5次失败，并且出现类似的堆栈跟踪。请有人帮助理解这个特征，并找到问题出现的地方，有可能寻找并修复？ 这里是一个堆栈跟踪：在量角器上运行测试时出错（未知错误：未定义updateWindow）

你可以显示你的代码失败的地方吗？没有查看您的代码，我们无法提出任何建议。谢谢 –
在代码中查找名为updateWindow的函数。当它被调用时，它没有被定义。通常这是由于试图在“this”对象上调用它造成的。 – MBielski
我没有函数和参数调用这种方式...它位于上方，然后我的代码...我发现它在node_modules中的文件pako.js和pako_inflate.js ... –
