如何访问带有白色的MessageBox?

问题描述

我在WPF应用程序中有一个简单的消息框，如下所示:

I have a simple message box in a WPF application that is launched as below:

private void Button_Click(object sender, RoutedEventArgs e)
{
   MessageBox.Show("Howdy", "Howdy");
}

我可以让白色单击我的按钮并启动消息框.

I can get white to click my button and launch the message box.

UISpy将其显示为我的窗口的子级，我无法确定访问它的方法.

UISpy shows it as a child of my window I couldn't work out the method to access it.

如何访问我的MessageBox以验证其内容?

How do I get access to my MessageBox to verify its contents?

推荐答案

找到了！窗口类具有一个可完成此操作的MessageBox方法:

Found it! The window class has a MessageBox method that does the trick:

        var app = Application.Launch(@"c:\ApplicationPath.exe");
        var window = app.GetWindow("Window1");
        var helloButton = window.Get<Button>("Hello");
        Assert.IsNotNull(helloButton);
        helloButton.Click();
        var messageBox = window.MessageBox("Howdy");
        Assert.IsNotNull(messageBox);
