WinAppDriver crashes when I call element.Text

I use element.FindElementsByXPath(“//*”) to get all child elements of a message box dialog. Then when I go through the element list calling subElement.Text on each causes WinAppDriver to crash on 4th sub element. I can see that the correct GET …/text is called but that kills WinAppDriver .exe. My application is a Windows Forms app that calls MessageBox.Show to show a message box dialog.

My test code is

    [TestMethod]
    public void MessageBox()
    {
      var capabilities = new DesiredCapabilities();
      capabilities.SetCapability("app", @"D:\MessageBoxSample\bin\Debug\MessageBoxSample.exe");

      var driver = new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), capabilities);

      var window = driver.FindElementByAccessibilityId("Form1");
      var button = window.FindElementByAccessibilityId("button1");
      button.Click();

      var messageBox = window.FindElementByClassName("#32770");
      var elements = messageBox.FindElementsByXPath("//*");

      foreach (var element in elements)
      {
        var str = element.Text;
      }
    }

You can find the MessageBoxSample.exe here MessageBoxSample.zip

Thanks. I can wait for the next version. The purpose of calling Text attribute of each element is just to collect the strings that are present on the UI at that moment. I am writing a localization testing tool. Previously be used UI automation on Windows but now studing if we can switch to WebDriver because we need use it anyway with web and mobile applications.

I am happy that you fix this because it is quite common that application just call Message.Show with one parameter like in my sample.

    private void button1_Click(object sender, EventArgs e)
    {
      MessageBox.Show("This is a sample");
    }

I tested a case when I also pass Caption and it indeed works.

Hi @timotiusmargo,
i would like to get a text from an app from the username field after sending keys to my project login username field, Send keys are working, but I’m unable to get a text from it. I’m used getText(), and also .getAttribute(“Value.Value”) , but both are not working. do you know any other way to get a text? Otherwise, is there any way to verify username fields without getting a text from it and make assertions??
