添加一个新的对象到列表中，那么已经存储的对象将被新的对象覆盖

我想问一些帮助！我使用WebDriver编写自动化测试，并具有下面的代码。这种静态方法的目的是从页面的certian部分收集对象。添加一个新的对象到列表中，那么已经存储的对象将被新的对象覆盖

正如你所看到的，我使用for循环来修改定位器值，我测试定位器是否显示它。如果它被显示，那么我启动MenuGroupObject对象，然后将它放入一个List对象，它是最后的返回值。

请看看代码片段下面的输出结果。

public static List<MenuGroupPageObject> GetListOfMenuGroups(IWebDriver webDriver) 
    { 
     var listOfMenuGroupPageObjects = new List<MenuGroupPageObject>(); 

     var menuGroupLocatorPattern = MenuBarLocatorHelper.GetMenuBarRootLocator() + 
             MenuBarLocatorHelper.GetLocatorPatternForMenuGroups(); 

     for (var i = 1; i < 20; i++) 
     { 
      var realMenuGroupNameLocator = menuGroupLocatorPattern.Replace(
       MenuBarLocatorHelper.GetThePureMenuGroupLocatorPatternForMenuGroups(), i.ToString(CultureInfo.InvariantCulture)); 

      if(SafeElementHandler.IsElementPresent(webDriver,By.XPath(realMenuGroupNameLocator))) 
      { 
       var menuGroupObject = new MenuGroupPageObject(webDriver, realMenuGroupNameLocator); 
       listOfMenuGroupPageObjects.Add(menuGroupObject); 

       foreach (MenuGroupPageObject listOfMenuGroupPageObject in listOfMenuGroupPageObjects) 
       { 
        Console.WriteLine("mainlocators in the bag round: " + i + "... " + listOfMenuGroupPageObject.GetMainLocator()); 
       } 
      } 
     } 

     return listOfMenuGroupPageObjects; 
    }

所以，结果是这样的：

mainlocators in the bag round: 1... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[1] 

mainlocators in the bag round: 2... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[2] 
mainlocators in the bag round: 2... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[2] 

mainlocators in the bag round: 3... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[3] 
mainlocators in the bag round: 3... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[3] 
mainlocators in the bag round: 3... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[3] 

mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[4] 
mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[4] 
mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[4] 
mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[4] 

mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[5] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[5] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[5] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[5] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[5]

你应该注意到的是，在每一轮中已经存储对象（S）将被最新的覆盖。但是，它应该是这样的：

mainlocators in the bag round: 1... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[1] 

mainlocators in the bag round: 2... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[1] 
mainlocators in the bag round: 2... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[2] 

mainlocators in the bag round: 3... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[1] 
mainlocators in the bag round: 3... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[2] 
mainlocators in the bag round: 3... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[3] 

mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[1] 
mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[2] 
mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[3] 
mainlocators in the bag round: 4... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[4] 

mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[1] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[2] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[3] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[4] 
mainlocators in the bag round: 5... //div[@id='contentContainer']/div[@id='container']/div[@id='leftHandMenubar']/ul[5]

我的问题是，什么是错的？我在c＃中检查了列表<>，并且我还没有发现任何缺少的东西（缺少构造器参数或类似的东西）会导致类似这样的事情。

我读过这篇文章三次，不知道你的实际问题是什么。 –

使用调试器来解决这个问题。 –

问题出在'MenuGroupPageObject'对象上。检查你的构造函数并检查'GetMainLocator'方法。 – mcabral

正如我在我的评论中写的，MenuPageObject对象有一个静态字段。
