无法使用TestStack.White访问树节点

Question

我试图用TestStack.White自动化视图，但无法处理树和树项。

在Outlook的日历视图中，有一个具有以下结构的日历文件夹树：

​

​

SearchCriteria searchCriteria = SearchCriteria.ByText("Calendar Folders").AndControlType(ControlType.Tree).AndIndex(0);
Tree calendarTree = (Tree)WhiteWindows.mainWindow.Get(searchCriteria);

calendarTree.Click(); // this action is performed correctly - clicks on the tree

Console.WriteLine("No. of nodes: " + calendarTree.Nodes.Count); // this line throws an exception

一些东西：

对于以下代码，也发生了相同的异常：

foreach(TreeNode node in calendarTree.Nodes) // Exception thrown here
{
    //perform action on nodes
}

有人有办法解决这个问题吗？

Answer 1

我们遇到了同样的问题。好像是个虫子。我们开发的解决方法是以IUIItems而不是TreeNodes的形式与节点交互。您必须编写一些与它们交互的定制代码，但至少它允许您执行单击操作等。

Answer 2

看来它已经起作用了。TestStack.White 0.13.3 + UIAComWrapper 1.1.0.14

Tree tree = mainWindow.Get<Tree>("treeMenu"); //primaryId
tree.Click();
MessageBox.Show(tree.Nodes.Count.ToString());
