how to run unit test as uwp

[abdelrahman-alfar]

• I packaged my app to UWP to be able to use toastnotification
• but when I write unit tests it fails system.AggregateException : One or more errors occurred. ---- System.Exception : Element not found. (Exception from HRESULT: 0x80070490)
• Same behavior if i start the application not as deployed version

So my question is how to make the unit test starts as deployed version not desktop?
