Selenium Webdriver警告 - 无效令牌“屏幕”

我是Selenium Webdriver中的新成员。当我使用这段代码时，我得到了输出和警告。请帮助我，我怎样才能忽略这个警告。我的代码是：Selenium Webdriver警告 - 无效令牌“屏幕”

package com.webdriver.Webdriver; 

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.htmlunit.HtmlUnitDriver; 

public class Example { 

    public static void main(String[] args) { 
     // Create a new instance of the html unit driver 
     // Notice that the remainder of the code relies on the interface, 
     // not the implementation. 
     WebDriver driver = new HtmlUnitDriver(); 
     // And now use this to visit Google 
     driver.get("https://mobile.twitter.com/andres/about"); 
     // Find the text input element by its name 
     //WebElement element = driver.findElement(By.xpath("//title")); 
     WebElement element = driver.findElement(By.xpath("//div[@class='footer']/strong/a")); 
     String s=element.getText(); 
     // Enter something to search for 
     //element.sendKeys("Cheese!"); 
     // Now submit the form. WebDriver will find the form for us from the element 
     //element.submit(); 
     // Check the title of the page 
     System.out.println("Page title is: " + driver.getTitle()); 
     System.out.println(s); 
     driver.quit(); 
     } 

}

为https://mobile.twitter.com/andres/about页面的CSS文件中包含意外/不支持/断码。

您有两种选择：用SilentCssErrorHandler替换DefaultCssErrorHandler或将其替换为仅过滤这些特定错误的默认实现（将错误消息与输出中显示的字符串相匹配）。

要安装自定义处理程序：

HtmlUnitDriver driver = new HtmlUnitDriver(); // Can't use generic driver anymore 
driver.getWebClient().setCssErrorHandler(handler); // install your handler

'getWebClient（）'不是公共方法。 – Bombe

上面的代码是从我的项目复制并粘贴的。如果该方法不再公开，则可以获取源代码并将其公开，或者使用反射来调用它。 *叹气*当单元测试库与你争吵时，你不也讨厌它吗？ –

您需要实现自己的HtmlUnitDriver子类，然后设置cssErrorHandler为SilentCssErrorHandler实例。

这可以很容易地用内部类实现，重写构造并设置错误处理程序：

import com.gargoylesoftware.htmlunit.SilentCssErrorHandler; 
import org.openqa.selenium.htmlunit.HtmlUnitDriver; 

public abstract class MyBaseTestCase { 
    protected HtmlUnitDriver webDriver = new SilentHtmlUnitDriver(); 

    protected class SilentHtmlUnitDriver extends HtmlUnitDriver { 
     SilentHtmlUnitDriver() { 
      super(); 
      this.getWebClient().setCssErrorHandler(new SilentCssErrorHandler()); 
     } 
    } 
}

然后你可以扩展这个基类，并访问webdriver的对象，并享受免费的垃圾邮件输出！
