C# TestStack.White - 从最小化的窗口中正确获取 Window.Items

Question

我目前正在使用TestStack.White 框架从外部Window 检索信息。

当 Window.DisplayState 是 Restored 或 Maximized 时，我可以完美地得到我想要的项目...但是当它是最小化，我无法从窗口中看到每个项目...以下示例显示了使用 Visual Studio 即时窗口中的命令的 Google Chrome 项目：： p>

最大化窗口：

Window.DisplayState (COMMAND)
Maximized
Window.Items (COMMAND)

Count = 35
[0]: {Panel. AutomationId:183101736, Name:Chrome Legacy Window, ControlType:painel, FrameworkId:Win32}

如你们所见，上面的例子在Window最大化时显示了35个项目，而Window最小化只显示了18个项目。

如果我想要Panel183101736（最大化Window中的第一位），可以使用以下代码轻松获得：

TestStack.White.UIItems.Panel panel = Window.Get<TestStack.White.UIItems.Panel>(SearchCriteria.ByAutomationId("183101736"));

如果Window是Minimized，我必须使用Window.DisplayState = DisplayState.Maximized手动更改其状态...否则，它将引发以下问题Exception。有没有办法在不强制打开 Window 的情况下获取“每个”项目？

Answer 1

我认为 UIItems 只是在它们被渲染时才存在。不会呈现最小化的窗口，因此找不到 UIItems。 要获取项目，窗口需要处于活动状态，而不是最小化并且在前台。

这是关于最后一部分的问题： Is there any way to activate a window with White?

它本质上就像使用这些现代 javascript 页面进行 WebScraping 一样，您无法抓取尚未加载到 dom 中的内容。与 rest-service（或对于 windows-automation 一个适当的 ipc）相反，它处理呈现的界面，“模拟”人类用户 - 并且仅限于他将呈现的项目。
