Fedora Checksum Tester is a little script that can automatically run checksum tests as defined in https://fedoraproject.org/wiki/QA:Testcase_Mediakit_Checksums.
The program is packed for PyPi, so you can install it easily using the pip command.
pip install --user fedora_checksum_tester
Navigate into the directory where you have downloaded the images to check and
run fedora_checksum_tester with those options. If you have not downloaded any
images to check, the program downloads the images automatically from Koji.
--release : The release number of the Fedora compose, for which you want to download the images. Rawhide is used by default.
--compose : The compose identification. Mostly, this is a date in the form of YYYYMMDD except for the release candidates. If left out, the number is calculated from the actual date, but it only works for Rawhide images.
--arch : Architecture for which to download the images. x86_64 used by default.
--variant : One possible variant, such as Cloud, Everything, Server, Spins, Workstation.
--subvariant : Can be used with Spins variant, to distinguish between various spins, such as KDE, LXCD, Xfce. If left out, all spins will be tested.
--type : Can be used with Server to distinguish between boot and dvd.
--purge : If set to True, all downloaded images will be deleted after the test has finished, independently of the result.
--forcedownload : Not yet implemented. This, if set to True will download the image even if it has been previously downloaded.
