selenium - polymer 网络组件测试仪/ Selenium 停滞不前

Question

我们正在尝试运行 Web-Component-tester，但它在 Selenium 步骤上一直停滞不前。

当我运行wct -l chrome --verbose

我得到以下内容

hook: prepare
hook: prepare:selenium
hook done: prepare:selenium
Starting Selenium server for local browsers
11:47:46.357 INFO - Launching a standalone server

11:47:47.935 INFO - Started org.openqa.jetty.jetty.Server@11bc7ed

然后在停滞几分钟后，它会跟进

hook done: prepare with error: [Error: Unable to connect to selenium]
Error: Unable to connect to selenium

从浏览器运行这些相同的测试没有问题。

虽然它已挂起，我们仍然可以通过浏览器连接到 http://127.0.0.1:11655/wd/hub

我尝试过谷歌搜索，但运气不佳。

可能会出现哪些问题或者如何进一步调试？

Answer 1

其中一个节点模块不使用 Internet Explorer 代理值。

在您的环境变量中创建一个新变量

• 名称:no_proxy
• 值:本地主机，127.0.0.1

应用后不要忘记重新启动 shell session
