登录时的代码：

                getUserName().sendKeys(username);
                logger.info("password="+password);
                getPassword().clear();
                getPassword().sendKeys(password);
                getLoginObject().click();
                logger.info("login successful");
                logger.info("Title()="+webTest.getTitle());

新建时的代码：
public static void createEssential(String name,String event_code){
               
                webTest.findElementByXpath("//i[@class='icons-add-plus btn']").click();
                webTest.waitTime();

                webTest.findElementById("atomicevent_event_code").sendKeys(event_code);
               
        }

掉渣饼

你可以在这行代码前面加个等待时间试试
webTest.findElementByXpath("//i[@class='icons-add-plus btn']").click();

加了等待时间，但还是不行，还发现有一个错
Marionette: Element does not support any accessible actions -> id: , tagName: I, className: atomic-events-management-ico

重定位句柄，但是还是不对
public static  void closeParentWindow(){
                logger.info("WindowHandle(1)="+webTest.getWindowHandle());
                webTest.getDriver().manage().window().maximize();
               
                String currentWindow = webTest.getWindowHandle();
                //得到所有窗口的句柄
                Set<String> handles = webTest.getWindowHandles();
                handles.remove(currentWindow);
                 String child_handle = (String)handles.iterator().next();
                 webTest.switchToWindow(currentWindow);
                 webTest.close();
                 webTest.setDriver(webTest.switchToWindow(child_handle));
                 
                logger.info(webTest.getTitle()+","+webTest.getCurrentUrl());
        }

加了等待时间也不对
Marionette: Element does not support any accessible actions -> id: , tagName: I, className: atomic-events-management-icon

如果打开新的页面是新的frame，首先要跳到新的frame，否则一直在老的页面会一直找不到元素。 switch_to_frame("frame")

是的，原来是嵌套在iframe标签中了
