Opinions requested, please. I lave a large C# application that primarily has many custom data entry pages. It also produces on-screen graphics.

I want to produce a test application to controlthe target application via the UI. I can make minor mods to the target,such as adding AutomationId to the various UI elements for easier access.

My question:
What are the preferred test platforms? I wouldlike the test app to use C#, but am comfortable with Python, Java, and other languages.

TIA

What I have tried:

Most of my searching has yielded 10+ year old advice, or general automation information,such as for unit testing.

Solution 1

There is no information given on how the application was built.

This is where thee Mvvm design pattern excels. It allows for Unit testing - ref: MVVM - Writing a Testable Presentation Layer with MVVM | Microsoft Learn[^]

For UI testing, look at using AutomationPeer: UI Automation of a Custom Control - WPF .NET Framework | Microsoft Learn[^]

Thank you Graeme_Grant. Not sure how to answer yout "How is it built" question. I will need to treat he target app as a "Black Box", except I am one of the developers. It does use MVVM patterns. It also has extensive unit testing. The customer is requesting testing at he UI levelas well.

I will review AutomationPeer - I haven't seen this one before

If the ViewModel, Model, service, etc, and they have one or more public methods with a return value, then you can run a unit test against it.

I like to use xUnit[^] and Fluent Assertions[^] for testing.

Can't see it. What with scroll bars, view ports, view boxes, sliders, ... You have acceptance tests (scripts) for a given use case. Once upon a time there were only textboxes and buttons. If that is "how your app is built", then I would say automation is "feasible"; otherwise, it's just pain.

If you are still looking for a solution, I have automated an windows application [WPF] with Java and Appium[selenium], you can also use C# which will also work. I have also used winApp driver to locate the elements.

WOW I forgot I asked this question a year ago!!!
Thank you for your response.

I settled on custom C# code that uses FlaUI as the base library. Works sufficiently well.
