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?

For simulating X11 mouse events you have several options:

If your X server supports XTEST extension (usually it does), then use XTEST Extension Library with functions XTestFakeKeyEvent,XTestFakeMotionEvent, etc. An example
You can use XLib functions like XSendEvent, XWarpPointer, etc. An example
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. An example

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

Is there anything similar for Wayland? – vinnylinux Jul 28 '18 at 18:05
BTW, the link of your first example is broken. – vinnylinux Jul 28 '18 at 18:06
For `Wayland` you can use `uinput` kernel module: https://www.kernel.org/doc/html/v4.12/input/uinput.html. And I've checked the link in my first example - it works – SergeyLebedev Jul 28 '18 at 19:22

@vinnylinux, you are right, sorry, I didn't meant linking to the current post. Fixed the link – SergeyLebedev Jul 30 '18 at 09:43
Unfortunately, that example doesn't work. Not even with XTestFakeKeyEvent. :( – vinnylinux Jul 30 '18 at 14:15

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.
