//使用这个修改过CssErrorHandler的类即可屏蔽HtmlUnitDriver的annoying warnings

public class ErrorLessDriver extends HtmlUnitDriver {
 
    public class Ignore implements ErrorHandler {
        @Override
        public void error(CSSParseException arg0) throws CSSException {
        }
 
        @Override
        public void fatalError(CSSParseException arg0) throws CSSException {
        }
 
        @Override
        public void warning(CSSParseException arg0) throws CSSException {
        }
 
    }
 
    public ErrorLessDriver(BrowserVersion chrome16) {
        this.getWebClient().setCssErrorHandler(new Ignore());
    }
