C＃TestStack.White-從最小化的窗口正確獲取Window.Items

Question

我目前正在使用TestStack.White框架從外部Window檢索信息。

當Window.DisplayState 恢復或最大化時 ，我可以完美地獲取所需的項目...但是當其最小化時 ，我無法從Window中看到每個項目...以下示例顯示了Google Chrome項目在Visual Studio 即時窗口中使用命令：

最大化的窗口：

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

Count = 35
[0]: {Panel. AutomationId:183101736, Name:Chrome Legacy Window, ControlType:painel, FrameworkId:Win32}
[1]: {MenuBar. AutomationId:SystemMenuBar, Name:Barra de menus do sistema, ControlType:barra de menus, FrameworkId:Win32}
[2]: {Button. AutomationId:Minimize, Name:Minimizar, ControlType:botão, FrameworkId:Win32}
[3]: {Button. AutomationId:Restore, Name:Restaurar, ControlType:botão, FrameworkId:Win32}
[4]: {Button. AutomationId:Close, Name:Fechar, ControlType:botão, FrameworkId:Win32}

[8]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[9]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[10]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[11]: {Tab. AutomationId:, Name:, ControlType:guia, FrameworkId:}
[12]: {Button. AutomationId:, Name:Nova guia, ControlType:botão, FrameworkId:}
[13]: {Button. AutomationId:, Name:Fechar, ControlType:botão, FrameworkId:}

[17]: {Button. AutomationId:, Name:Fechar, ControlType:botão, FrameworkId:}
[18]: {Button. AutomationId:, Name:Fechar, ControlType:botão, FrameworkId:}
[19]: {Button. AutomationId:, Name:Fechar, ControlType:botão, FrameworkId:}
[20]: {Button. AutomationId:, Name:Fechar, ControlType:botão, FrameworkId:}
[21]: {ToolStrip. AutomationId:, Name:main, ControlType:barra de ferramentas, FrameworkId:}
[22]: {Button. AutomationId:, Name:Recarregar, ControlType:botão, FrameworkId:}
[23]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[24]: {Button. AutomationId:, Name:Adicionar esta página aos favoritos, ControlType:botão, FrameworkId:}
[25]: {CustomUIItem. AutomationId:, Name:Extensões, ControlType:personalizado, FrameworkId:}
[26]: {Button. AutomationId:, Name:AdBlock - clique para detalhes, ControlType:botão, FrameworkId:}
[27]: {Button. AutomationId:, Name:Tampermonkey, ControlType:botão, FrameworkId:}
[28]: {ToolStrip. AutomationId:, Name:Favoritos, ControlType:barra de ferramentas, FrameworkId:}
[29]: {Button. AutomationId:, Name:AAA, ControlType:botão, FrameworkId:}
[30]: {Button. AutomationId:, Name:BBB, ControlType:botão, FrameworkId:}
[31]: {Button. AutomationId:, Name:CCC, ControlType:botão, FrameworkId:}
[32]: {Button. AutomationId:, Name:DDD, ControlType:botão, FrameworkId:}
[33]: {Button. AutomationId:, Name:EEE, ControlType:botão, FrameworkId:}
[34]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}

最小化的窗口：

Window.DisplayState (COMMAND)
Minimized
Window.Items (COMMAND)

Count = 19
[0]: {MenuBar. AutomationId:SystemMenuBar, Name:Barra de menus do sistema, ControlType:barra de menus, FrameworkId:Win32}
[1]: {Button. AutomationId:Restore, Name:Restaurar, ControlType:botão, FrameworkId:Win32}
[2]: {Button. AutomationId:Maximize, Name:Maximizar, ControlType:botão, FrameworkId:Win32}
[3]: {Button. AutomationId:Close, Name:Fechar, ControlType:botão, FrameworkId:Win32}
[4]: {CustomUIItem. AutomationId:, Name:Google Chrome, ControlType:personalizado, FrameworkId:}
[5]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[6]: {Button. AutomationId:, Name:Murilo, ControlType:botão, FrameworkId:}
[7]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[8]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[9]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[10]: {Tab. AutomationId:, Name:, ControlType:guia, FrameworkId:}
[11]: {Button. AutomationId:, Name:Nova guia, ControlType:botão, FrameworkId:}
[12]: {ToolStrip. AutomationId:, Name:main, ControlType:barra de ferramentas, FrameworkId:}
[13]: {Button. AutomationId:, Name:Recarregar, ControlType:botão, FrameworkId:}
[14]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}
[15]: {Button. AutomationId:, Name:Adicionar esta página aos favoritos, ControlType:botão, FrameworkId:}
[16]: {CustomUIItem. AutomationId:, Name:Extensões, ControlType:personalizado, FrameworkId:}
[17]: {ToolStrip. AutomationId:, Name:Favoritos, ControlType:barra de ferramentas, FrameworkId:}
[18]: {CustomUIItem. AutomationId:, Name:, ControlType:personalizado, FrameworkId:}

大家可以看到，當Window 最大化時，上面的示例顯示了35個項目，而Minimized Window僅顯示了18個項目。

如果我想要Panel 183101736（ 最大化 Window第一個位置），可以使用以下代碼輕松獲得：

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

如果將Window 最小化 ，則必須使用Window.DisplayState = DisplayState.Maximized ...手動更改其狀態，否則，它將引發以下Exception 。 有沒有一種方法可以在不強制打開Window情況下獲取“每個”項目？

Answer 1

我認為UIItems僅在渲染時出現。 最小化的窗口不會被渲染，因此找不到UIItems。 要獲取項目，窗口需要處於活動狀態，而不是最小化，並且處於前台。

這是關於最后一部分的問題： 是否可以用White激活窗口？

從本質上講，就像使用這些現代javascript頁面進行Web抓取一樣，您無法抓取尚未加載到dom中的內容。 與休息服務（或用於Windows自動化的適當ipc）相反，它使用呈現的界面來處理，“模擬”人類用戶-並且限於他將要呈現的項目。
