WinAppDriver not finding UWP app by ID even though the app is installed

[nathan-alden-hp]

Proof that my UWP app is installed (Visual Studio installs it when I run it in Debug configuration):

PS > Get-AppxPackage -AllUsers | ?{ $_.Name.Contains("52a95998-8cfa-43d7-96c9-06fc6d8ad1c5") }

Hi @nathan-alden-hp

Can you run get-StartApps via powershell and confirm the app name?

[nathan-alden-hp]

PS > Get-StartApps | ?{ $_.Name.Contains("XamlUwpApp") }

Name       AppID
----       -----
XamlUwpApp 52a95998-8cfa-43d7-96c9-06fc6d8ad1c5_x38zh4nq6sjk4!App

[nathan-alden-hp]

FWIW, I updated the Appium.WebDriver package to 4.0.0. I got some obsolete warnings, so I updated my test code to this:

var options = new AppiumOptions();

options.AddAdditionalCapability("app", "52a95998-8cfa-43d7-96c9-06fc6d8ad1c5_0.0.0.0_x64__x38zh4nq6sjk4!app");

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

windowsDriver.FindElementByAccessibilityId("UIGenerateRandomEquationButton").Click();

However, the driver still reports the same error.

Also note that this app is being side-loaded by using the Add-AppDevPackage.ps1 script generated by the Store app package build in Visual Studio. The self-signed certificate used to sign the bundle was added to the Trusted Root Certification Authorities store by the script.

Hi @nathan-alden-hp

Try passing in just the following for the AppID - since it looks like there is a variation what is being reported.

52a95998-8cfa-43d7-96c9-06fc6d8ad1c5_x38zh4nq6sjk4!App

If that doesn't work, then I'd recommend using a Desktop Session.

Hello @hassanuz,

I am facing the similar issue. Not able to launch my app through App ID.

Could you please suggest me the fix?
