List of variables usable in tests

This list contains variables that are possible to set/redefine in WebUI and get their values in tests. This document merges relevant variables from official documentation (backend variables), variables that control flow through main.pm (test variables) and variables that are specified when ISO is posted into OpenQA (run variables).

Backend variables

These variables control settings of underlying virtual machine where tests runs on. Some of them (ARCH, QEMURAM, ...) should be set per machine, others (HDD_$i, HDDMODEL, ...) should be set per test and some of them (KEEPHDDS, MAKETESTSNAPSHOTS, SKIPTO) should be set only during development and debugging.

Variable	Values allowed	Default value	Explanation
ARCH	x86_64, i686, aarch64, ...	depends on tested medium	architecture of VM
BIOS	filename	ovmf-x86_64-ms.bin for x86_64 UEFI, not set otherwise	set different BIOS
BOOTFROM	characters (see man qemu, -boot order= option)	not set	boot from different medium than CD
CDMODEL	see qemu-kvm -device help	not set/Qemu default	type of device for CD
HDDMODEL	see qemu-kvm -device help (e. g. PATA = id-hd, SATA = ide-hd,bus-ahci0.0, SCSI = virtio-scsi-pci)	virtio-blk	type of device for HDD
HDDSIZEGB	integer	10	size (in GBs) for disks that are created automatically
HDD_$i (HDD_1, HDD_2, ...)	filename	not set	attach additional HDD to VM
ISO	filename	not set	attach CD drive with ISO inserted
ISO_$i (ISO_1, ISO_2, ...)	filename	not set	additional CD drives to by attached
KEEPHDDS	boolean	false/not set	don't delete HDD after test finishes
LAPTOP	boolean or filename	false/not set	if true, Dell E6330 DMI is used; if set to filename, that file is used for DMI
MAKETESTSNAPSHOTS	boolean	false/not set	save snapshot for each test
NOVIDEO	boolean	false/not set	don't create video output if set
NUMDISKS	integer	1	number of disks to be created and attached to VM
PART_TABLE_TYPE	mbr, gpt	not set	what type of partition table should attached HDD have
PXEBOOT	boolean	false/not set	boot VM from PXE (network)
QEMU	filename, path to Qemu binary	not set	filename of Qemu binary
QEMUCPU	see qemu-kvm -cpu help	not set	CPU to emulate
QEMUCPUS	integer	1	number of processor cores to use for Qemu
QEMURAM	integer	1024	size of RAM to use (in MiB)
QEMUTHREADS	integer	0	number of CPU threads to use for Qemu
QEMUVGA	see qemu-kvm -device help	cirrus (should be set to std on Fedora, cirrus driver was retired)	display device to use for VM
QEMU_COMPRESS_QCOW2	boolean	false/not set	compress qcow2 images
SKIPTO	name of snapshot	not set	restore VM from given snapshot - better used with MAKETESTSNAPSHOTS
UEFI	boolean	false/not set	whether to use UEFI (UEFI BIOS files should be installed)
UEFI_BIOS	filename	false/not set, ovmf-x86_64-ms.bin when UEFI is set	filename of UEFI BIOS
USBBOOT	boolean	false/not set	if set, mount ISO as USB and boot from it

For additional (kvm2usb, IPMI...) as well as for other Qemu variables, see official documentation.

Test variables

These variables control flow through main.pm - by setting them, you can alter what parts will be loaded.

There are certain tests that conflict each other. Note that conflict is always mutual, but for simplification purposes, only one side of this conflict is shown (that means, if it's shown that A conflicts B, it also means that B conflicts A even if not shown in the table).

Variable	Values allowed	Default value/behavior	Conflicts	Explanation
LIVE	boolean	not set	technically PACKAGE_SET, KICKSTART, MIRRORLIST_GRAPHICAL, REPOSITORY_GRAPHICAL, REPOSITORY_VARIATION	specify that the test is running on Live system - additional steps are required (starting Anaconda...)
PACKAGE_SET	string (minimal, default, ...)	minimal; default when LIVE is set	nothing	sets packageset to install - you have to add appropriate needles, see tests/_software_selection.pm
ENTRYPOINT	filename	not set	N/A	set ENTRYPOINT to load specific test directly (bypass modular structure, mainly usable for testing)
UPGRADE	string (minimal, desktop, encrypted, ...)	not set	all except of LIVE and USER_PASSWORD	when set, do an upgrade test of specified type
KICKSTART	boolean	false/not set	all	when specified, do an kickstart installation (you should use GRUB variable to specify where kickstart file resides)
MIRRORLIST_GRAPHICAL	boolean	false/not set	REPOSITORY_GRAPHICAL	sets installation source to mirrorlist
REPOSITORY_GRAPHICAL	url to repository (without arch and /os, for example http://dl.fedoraproject.org/pub/fedora/linux/development)	not set	MIRRORLIST_GRAPHICAL	sets installation source to repository url in Anaconda
REPOSITORY_VARIATION	url to repository (without arch and /os, for example http://dl.fedoraproject.org/pub/fedora/linux/development)	not set	nothing	sets installation source to repository url in GRUB
PARTITIONING	string (custom_software_raid, guided_delete_all, ...)	guided_empty	nothing	load specified test for partitioning part (when PARTITIONING=guided_delete_all, tests/disk_guided_delete_all.pm is loaded) and optionally post-install partitioning check (if tests/disk_guided_delete_all_postinstall.pm exists, it will be loaded after login to the installed system). Also, if value starts with custom_, the select_disks() method will check the custom partitioning box
ENCRYPT_PASSWORD	string	not set	nothing	if set, encrypt disk with given password
DESKTOP	boolean	false/not set	nothing	set to indicate that Fedora is running with GUI (so for example OpenQA should expect graphical login screen)
ROOT_PASSWORD	string	weakpassword	nothing	root password is set to this value
GRUB	string	not set	nothing	when set, append this string to kernel line in GRUB
USER_LOGIN	string	not set	should be used with USER_PASSWORD (unless false)	when set, user login is set to this value. If not set, default value test is used for console installs, no login is done for graphical installs. If set to false, no user login will be done
USER_PASSWORD	string	not set	should be used with USER_LOGIN	when set, user password is set to this value. If not set, default value weakpassword is used for console installs, no login is done for graphical installs
BOOT_UPDATES_IMG_URL	boolean	false/not set	set to indicate that path to updates.img was appended to kernel line
POSTINSTALL	string	not set	nothing	If set, tests/(value)_postinstall.pm will be loaded after install, boot, login, and other postinstall tests
UEFI	boolean	false/not set	nothing	whether to use UEFI, this variable isn't usually set in test suites but in machine definition

Run variables

These variables should be set when tests are scheduled (when running isos post).

Variable	Explanation
ISO	contains filename of ISO that is used for booting. If ISOURL is not set, file must exist in /var/lib/openqa/share/factory/iso. If ISOURL is set, it will be downloaded to this name instead of its original name
ISO_URL	contains URL for ISO to boot, openQA will download it
DISTRI	contains distribution name (should be same as in WebUI, probably fedora)
VERSION	contains version of distribution
FLAVOR	indicates what type of distribution is used. Three Pungi properties, joined with -: variant, type, and format. e.g.: Server-dvd-iso. Special value universal is used to schedule the group of tests that should be run once each per arch per compose, against the 'best' available ISO
ARCH	is set to architecture that will be used (x86_64, i686)
BUILD	contains Pungi compose_id (something like Fedora-24-20160121.n.3)
