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.

The main goal of a Kernel Test Day is to test a new kernel on many different machines as possible.
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.
== How to participate in Kernel Test Days
== What to do during Kernel Test Days
These are the different ways to contribute in a Kernel Test Day
The first thing to do is to get the right kernel version to test.
These are the different ways to get the kernel to test:
=== Downloading a test day image
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 new kernel 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. see https://docs.fedoraproject.org/en-US/quick-docs/creating-and-using-a-live-installation-image/#proc_creating-and-using-live-usb[this guide]

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 then boot the live image and run the tests without worries of messing up with your OS.
=== Testing on a Virtual Machine
You can also install the new kernel 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.

During kernel test days, on the relative wiki page will be provided a link to download the newly built kernels directly from koji builds. This is recommended for secure boot users.

NOTE: *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!

To run the tests, you’ll need to install some packages:
Before testing, you need to install some packages:
sudo dnf install gcc git python-fedora keyutils libtirpc-devel
* If you are using the ‘test day image’ you will have the kernel-tests folder in your home folder. so you can enter the folder with cd ~/kernel-tests
* If you are using the _*test day image*_ you will have the kernel-tests folder in your home folder; you can enter the folder with
cd ~/kernel-tests
* If you are not using the test day image you will need to clone the kernel-tests repo.
Use this command in terminal:
git clone https://pagure.io/kernel-tests.git
this will download the same folder that you find in the test day image, with the testing scripts. When the download is finished, enter the kernel-tests folder

Here we can decide whether or not to upload the results of our tests to Fedora servers.
By default, running the tests will not automatically submit results.

Anyway, add whatever results you got from the tests on the dedicated result page of the Kernel Test day!
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 https://bugzilla.redhat.com[Bugzilla] bug , if you opened one against this kernel for a bug that you found.

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[Bugzilla]

*Done!*

Thanks for helping the fedora team in testing the newest kernel on your machine!
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.
