The main tasks it does is build on a few different distros as well as build with the various build options to make sure they work.It doesn't (yet) run the test suite runner because that one mostly requires device nodes to operate on. Most of the fancy is to get the docker images ready. A dnf update takes forever, so we don't want to do that on 10 different machines. So instead we build docker images with all the bits pre-installed, push that to the registry and use those images for testing. To speed things up, we only do that when the current image is older than a week. And we only do that when we push to libinput proper, so a merge request or pushing to your private gitlab repo will never trigger a docker image update - it will trigger the tests and use the docker images tough.

libinput
libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.
libinput provides device detection, event handling and abstraction so minimize the amount of custom input code the user of libinput need to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.
Architecture
libinput is not used directly by applications. Think of it more as a device driver than an application library. It is used by the xf86-input-libinput X.Org driver or Wayland compositors. The typical software stack for a system running Wayland is:
@dotfile libinput-stack-wayland.gv
The Wayland compositor may be Weston, mutter, KWin, etc. Note that Wayland encourages the use of toolkits, so the Wayland client (your application) does not usually talk directly to the compositor but rather employs a toolkit (e.g. GTK) to do so. The Wayland client does not know whether libinput is in use.
The simplified software stack for a system running X.Org is:
@dotfile libinput-stack-xorg.gv
libinput is not employed directly by the X server but by the xf86-input-libinput driver instead. That driver is loaded by the server on demand, depending on the xorg.conf.d configuration snippets. The X client does not know whether libinput is in use.
