The kernel team is working on final integration for kernel 5.6. This version was just recently released, and will arrive soon in Fedora.
Fedora kernel and QA teams have organized a test week from Monday, April 13, 2020 through Monday, April 20, 2020
It is pretty simple to test the kernel, you can find detailed instructions in this document: Kernel Test Days
As stated there, you could also install and test the new kernel on your Workstation/Server installation, on a bare metal machine, but make sure you have no important data on that installation, things might go wrong — don’t do this on your production machine!
So it is better to use a spare machine, a VM or use the live image that will be cooked for the occasion.
