使用 Selenium 和 C# 在 draggable=true 时拖放不工作 [英] Drag and drop not working using Actions when draggable=true using Selenium and C#

问题描述

元素被正确识别，我可以看到鼠标在这两个元素之间移动，但没有发生拖放.单击并按住时，UI 未显示任何突出显示.也没有错误.

Elements are identified correctly and i can see mouse moving between this two elements but drag and drop not happening. Ui not displayed any highlights when click and hold. No errors also.

我尝试了在不同讨论中提出的不同解决方案，但它们都不适合我

I have tried different solutions suggested on different discussions none of them working for me

我的代码

_actions = new Actions(Driver.WebDriver);
        var dragAndDrop = _actions.ClickAndHold(parentRow)
                                  .MoveToElement(childRow )
                                  .Release(target)
                                  .Build();
        dragAndDrop.Perform();
        Driver.Wait();

这就是我识别元素的方式

This is how i am identifying elements

 var childList =Driver.WebDriver.FindElements(By.ClassName("itl-treeNode-title"));
     var parentRow = childList.FirstOrDefault(x => x.Text.Equals(parentSrc)).FindElement(By.XPath("following-sibling::*[1]"));
     var childRow = childList.FirstOrDefault(x => x.Text.Equals(childSrc)).FindElement(By.XPath("following-sibling::*[1]"));

相同的代码可以在我们应用程序的另一个用户界面上运行.

Same code works on another ui on our application.

我现在已经像下面这样更改了我的代码，现在我得到了陈旧的元素异常——因为我需要动态识别这个元素，所以我不能使用这里提到的 POM 解决方案 https://www.softwaretestingmaterial.com/stale-element-reference-exception-selenium-webdriver/#How-To-Overcome-Stale-Element-Reference-Exception-in-Selenium

I have now changed my code like below and now i am getting stale element exception- Since i need to identify this element dynamically i can not use the POM solution mentioned here https://www.softwaretestingmaterial.com/stale-element-reference-exception-selenium-webdriver/#How-To-Overcome-Stale-Element-Reference-Exception-in-Selenium

var childList = Driver.WebDriver.FindElements(By.ClassName("itl-treeNode-title"));
     var parent = childList.FirstOrDefault(x => x.Text.Equals(parentSrc)).FindElement(By.XPath("parent::*"));
     var parentRow = parent.FindElement(By.ClassName("itl-treenode-content-cover"));
     var child = childList.FirstOrDefault(x => x.Text.Equals(childSrc)).FindElement(By.XPath("parent::*"));
     var childRow = child.FindElement(By.ClassName("itl-treenode-content-cover"));         
     childRow.Click();
     //try
     //{
     //   (new Actions(Driver.WebDriver)).DragAndDrop(childRow, parent).Perform();
     //}         
     //catch (Exception ex)
     //{
     //   throw new Exception("Failed to perform drag and drop ");
     //}
     new Actions(Driver.WebDriver).ClickAndHold(childRow)
               .MoveToElement(parent)
               .Release(parent)
               .Build()
               .Perform();
     Driver.Wait();

例外

OpenQA.Selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document
  (Session info: chrome=77.0.3865.120)
   at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse)
   at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
   at OpenQA.Selenium.Remote.RemoteWebDriver.PerformActions(IList`1 actionSequenceList)
   at OpenQA.Selenium.Interactions.Actions.Perform()

推荐答案

点击childRow后，再次构建webelement，避免stale element引用异常，示例代码如下.

After clicking on childRow, build the webelement again to avoid stale element reference exception, sample code below.

var childList = Driver.WebDriver.FindElements(By.ClassName("itl-treeNode-title"));
var parent = childList.FirstOrDefault(x => x.Text.Equals(parentSrc)).FindElement(By.XPath("parent::*"));
var parentRow = parent.FindElement(By.ClassName("itl-treenode-content-cover"));
var child = childList.FirstOrDefault(x => x.Text.Equals(childSrc)).FindElement(By.XPath("parent::*"));
var childRow = child.FindElement(By.ClassName("itl-treenode-content-cover"));    
childRow.Click();
childRow = child.FindElement(By.ClassName("itl-treenode-content-cover"));    
new Actions(Driver.WebDriver).ClickAndHold(childRow)
           .MoveToElement(parent)
           .Release(parent)
           .Build()
           .Perform();
Driver.Wait();
