WPF:如何在Appium中测试应用程序是否最小化

Question

在我的项目中，我想用appium和WinAppDriver测试我的应用程序的ui(用c# .net-core-5.0/WPF编写)。

第一步是实现我的应用程序的无边界设计，所以我使用了windowChrome功能，并建立了一个自定义的标题栏，最小化，恢复和关闭按钮。对于这个按钮，我现在想要编写测试用例。

测试代码应该直接....使用提供的appium驱动程序单击最小化，最大化按钮，并测试窗口对象具有的windowState属性。但是我不知道如何提取windowState属性。

[TestMethod]
public void TestMinimizeWindow()
{
session.FindElementByAccessibilityId("MinimizeButton").Click();
//how to extract the information whether the app is minmized, maximized or normal
var actualWindowState = ...
Assert.AreEqual(WindowState.Minimized,actualWindowState);
}

谁知道如何提取属性与appium/WinAppDriver?或者有人有其他解决办法吗?

正如Arkane的帖子所建议的那样，我创建了一个处理过程，从中我可以确定状态

namespace codedui_test
{
public enum ShowWindowCommands : int
{
Hide = 0,
Normal = 1,
Minimized = 2,
Maximized = 3,
}
[Serializable]
[StructLayout(LayoutKind.Sequential)]
public struct WINDOWPLACEMENT
{
public int length;
public int flags;
public ShowWindowCommands showCmd;
public System.Drawing.Point ptMinPosition;
public System.Drawing.Point ptMaxPosition;
public System.Drawing.Rectangle rcNormalPosition;
}
public class ProcessManager
{
protected Process process;
public ProcessManager(string processToWatch)
{

//get Handle of window to extract it's position and styles
Process[] processes = Process.GetProcesses();
foreach (Process proc in processes)
{
if (proc.ProcessName == processToWatch)
{
process = proc;
break;
}
}
}
public WINDOWPLACEMENT GetPlacement()
{
IntPtr hwnd = process.MainWindowHandle;
WINDOWPLACEMENT placement = new WINDOWPLACEMENT();
placement.length = Marshal.SizeOf(placement);
GetWindowPlacement(hwnd, ref placement);
return placement;
}
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
internal static extern bool GetWindowPlacement(IntPtr hWnd, ref WINDOWPLACEMENT lpwndpl);
}
}

在我的Testclass中，我现在能够创建一个processobject，从中我可以获得位置:

using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium.Appium.Windows;
namespace codedui_test
{
[TestClass]
public class MainWindowTest
{
protected static ProcessManager dSProcess;
[ClassInitialize]
public static void ClassInitialize(TestContext context)
{
//Setup Handle to Window to be able to determine it's size
dSProcess = new ProcessManager("ProgramName");
}
[TestMethod]
public void TestWindowControl()
{
session.FindElementByAccessibilityId("MaximizeButton").Click();
var placement = dSProcess.GetPlacement();
Assert.AreEqual("Maximized", placement.showCmd.ToString());
session.FindElementByAccessibilityId("RestoreButton").Click();
placement = dSProcess.GetPlacement();
Assert.AreEqual("Normal", placement.showCmd.ToString());
session.FindElementByAccessibilityId("MinimizeButton").Click();
placement = dSProcess.GetPlacement();
Assert.AreEqual("Minimized", placement.showCmd.ToString());
}
....further methods
}
}
