If I have understood you correctly:

1. You have been supplied an application written in WPF targeting the .NET Framework.
2. You want to test the user interface interactivity on this WPF application
3. You want to use LabVIEW to automate the testing of the WPF application.

This is possible but it is not a native LabVIEW feature - you need an API to call within LabVIEW itself using .NET or Win32 calls. You could use Microsoft's UI Automation framework; you can use it directly or preferably use a framework that wraps it like TestStack.White. Here's an old discussion although still relevant (https://stackoverflow.com/questions/58340/how-to-test-a-wpf-user-interface). Although most tutorials around will walk you through how to do it using Visual Studio you can execute the same library calls using LabVIEW .NET nodes, as long as you work within the normal limitations of .NET integration in LabVIEW (mostly generics - https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P8iWSAS).

I'm not aware of any convenient frameworks or tools provided by third parties specifically for LabVIEW to do what you want. Your best option is to use TestStack.White or FlaUI and make the necessary .NET calls in a LabVIEW VI(s). You can start here (https://teststackwhite.readthedocs.io/en/latest/ or https://github.com/Roemer/FlaUI). If you are not familiar with .NET or WPF then it could be a challenging process, especially if its 'urgent'.

Why are you trying to control a WPF UI using LabVIEW? What is the goal of this?

[tyk007]

Both tools I referred to are open source (if you take a look at the pages). As I said; I'm not aware of any specific example showing how to do what you are asking. If you are unfamiliar with the technologies and strategies involved then I would suggest that LabVIEW is probably not the best choice for what you are trying to achieve - save yourself some of the complexity and try following the examples written in C# targeting a .NET assembly.
