Hi,

I'm working on WinUI3 desktop application in CPP. I want to test my application for user interaction like keyboard input, mouse input, dragging widgets/ Window, sending OS events, etc. I tried simulating with SendInput API, it did work well, but is there any other options to simulate user interaction events with out any 3rd part application?

    Hi,

    Welcome to Microsoft Q&A!

    You could try to use Windows.UI.Input.Preview.Injection to simulate and automate user input from devices such as keyboard, mouse, touch, pen, and gamepad in your Windows applications.

    Please note that input injection APIs require restricted capabilities. You will need to add inputInjectionBrokered as estricted capability in your manifest first.

    <rescap:Capability Name="inputInjectionBrokered" />

    For more details you could refer to the Doc: Simulate user input through input injection

    Thank you
