During *Kernel Test Days*, contributors are asked to run a _Kernel Regression Test_ which will help to detect and troubleshoot any issue with a new kernel version, before wider usage.
It consist in running a series of tests provided by the https://pagure.io/kernel-tests[Kernel Test Suite]
The main goal of a Kernel Test Day is to test a new kernel on many different machines as possible, so every new Kernel Test Day is announced some days in advance with a https://fedoramagazine.org/[fedoramagazine] post.
During test days a dedicated wiki page will provide a link to download a *test day image* which is a live distro of Fedora with the kernel version to test already in it.
The test day image also contain the _test suite_, aka the scripts to test the kernel on your machine.
The downloaded .iso file must then be written in a bootable USB stick.
TIP: Check https://docs.fedoraproject.org/en-US/quick-docs/creating-and-using-a-live-installation-image/#proc_creating-and-using-live-usb[this guide] for creating a bootable USB stick.
You can also install the required kernel version on a Virtual Machine running an up to date Fedora release and do the test in the VM.
In this case you can just add https://copr.fedorainfracloud.org/coprs/jforbes/kernel-stabilization/[this] *Copr repository* on the Fedora distro running in your VM.
IMPORTANT: *Disclaimer*: 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!
Once inside the kernel-tests folder, it’s time to edit some configuration files; first we need to copy the content of the `config.example` file in a new hidden file named `.config`
During a kernel test day, a dedicated web application page is created for uploading results, there you can fill a form with a description of the results you got.
Just Click on the *Enter Result* button and fill the form.
Enter a username in the *Username* field, in the *Profile* field enter a description of the machine you tested the kernel on, and choose the result of your test from the dropdown menu (failed or pass).
In the *Bugs* field you can write the number of a bug (or bug numbers divided by semicolons. i.e. '752855;25532') that you opened on Bugzilla, against that particular kernel.
If you found a bug in the kernel, please report it via https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&component=kernel[this link.]
If you don't have a Bugzilla account,you can still log in with your FAS account.
NOTE: If a test fails repeatedly, consider helping by reporting the failure on https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&component=kernel[Bugzilla]
If you want to help more: join the https://fedoraproject.org/wiki/QA[Fedora Quality Assurance] team and propose new test cases for the kernel that are not already on https://fedoraproject.org/wiki/KernelRegressionTests[this] page.
