Windows 10 - How do I test touch events without a touchscreen?
Microsoft.Windows.Simulator.exe
Located in C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Simulator\16.0\Microsoft.Windows.Simulator.exe
The Simulator has modes that allow for basic touch events using the mouse, as well as pinch-to-zoom, and 2 finger rotation. It simulates your current Windows machine so you can even open up your code in VS, run your app, and set breakpoints that would normally only hit when using touch events.
Edit: based on the comment of Luishg, you need to install both Visual Studio and the Visual Studio UWP package for the Simulator to be installed.
You can actually launch this from visual studio now:https://docs.microsoft.com/en-us/visualstudio/debugger/run-windows-store-apps-in-the-simulator?view=vs-2019
Set the simulator as the target
To run your UWP app in the simulator, select Simulator from the drop-down list next to the Start Debugging button on the debugger Standard toolbar. This option is only available if your app's Target Platform Min. Version is less than or equal to the operating system on your development machine.
PS. mine didnt actually work first time I had to reboot my pc to get it working
