You've ran into an issue that has plagued software developers for many decades now - how do I test UI? The simplest answer is - don't. This is a generally accepted practice. Instead, design your application such that most of the logic is outside of the UI and built into components. You can then also design your UI logic of the application using patterns such as Model View Controller, Model View Presenter, and Model View View-Model which allow that logic to be tested. XAML based technologies typically lean towards the MVVM pattern.
