Simulating mouse and keyboard input on Wayland and X11

Question

I am working on a small acceptance test for my OpenGL application written in C. So far, I'm only able to take screenshots and haven't found a way of simulating mouse and keyboard input on both Wayland and X11.

Any suggestions on how to manipulate the event stream of a specific window in Wayland/X11?

Answer 1

For simulating X11 mouse events you have several options:

1. If your X server supports XTEST extension (usually it does), then use XTEST Extension Library with functions XTestFakeKeyEvent , XTestFakeMotionEvent , etc. An example
2. You can use XLib functions like XSendEvent , XWarpPointer , etc. An example
3. If you are under Linux and your tests have access to command shell then you can use command line tool xdotool (which internally uses XTEST extension . Anexample

For Wayland you can use uinput kernel module. Documentation and examples are here

Answer 2

keyboard is a Python library designed to emulate keyboard and mouse on both Linux (X11 only) and Windows. There may be a similar project that uses C, but I don't know of it yet.
