java - SoapUI项目执行后WebDriver异常

Question

请帮助解决以下问题。

我正在使用 Eclipse。我的主类调用下面的 2 个 class/java 文件。

1) Invoke_SoapUI_Project.java(这将执行 SOAP UI 项目)2) Run_Selenium_Script.java (这会从 Firefox 打开 URL 之一)。

我的主函数调用上面的Invoke_SoapUI_Project.java并触发“SOAP UI XML Project”的执行，并且运行良好。

然后我的第二个函数“Run_Selenium_Script.java”调用并尝试打开网页之一。但在我定义 webdriver 对象的行出现以下错误。即 driver= new firefoxDriver();

但是如果我评论 Invoke_SoapUI_Project.java，那么我不会遇到以下异常，firefox 对象会正确创建并打开我的 URL。

我遇到以下异常:

我们在这里偶然发现了似乎相同的问题(花了我们相当长的时间)，但我们设法解决了它:

问题似乎是 SoapUI 将默认 proxyselector 设置为 null，而 Apache httpclient 并不期望这样。

重现问题:

WsdlProject wsdlProject = new WsdlProject("");
WebDriver driver = new FirefoxDriver();

解决方法:

ProxySelector proxy = ProxySelector.getDefault();
WsdlProject wsdlProject = new WsdlProject("");
ProxySelector.setDefault(proxy);
WebDriver driver = new FirefoxDriver();

peidong-hu 两天前发送了一个独立补丁(从那里获取了解决方案): https://github.com/Ardesco/selenium-standalone-server-plugin/issues/23

我已经提交了 selenium 的错误报告，将使用以下详细信息更新它:https://github.com/SeleniumHQ/selenium/issues/388

我还将提交一份 SoapUI 报告。
