 Generally you want to prefix all new vars with `OPENQA_` as they will get auto
 routed all the way through to vars.json and thus `testapi::get_var`. Older vars
 do not have the prefix (yet).
 
 # Tooling Variables
 
 Tooling variables are used to influence our tooling but generally aren't
 available in os-autoinst (or have a different name, being env vars you could
 still fish them out of `ENV` I suppose).
 
 |Variable|Description|
 |--------|-----------|
 |QEMUVGA|Overrides the qemu VGA default.|
 |OPENQA_BIOS|Modifies the system to boot in BIOS mode instead of UEFI (our tooling only). In os-autoinst this var is `UEFI` and inverted.|
 |PLASMA_MOBILE|Enables special config for plasma mobile|
 |NO_CLEAN|Sets Jenkinsfile to not clean up workspace when the job ends (useful to inspect the disk image)|
 
 # Test Variables
 
 |Variable|Description|
 |--------|-----------|
 |TYPE|Identifies the image type. This is the ISO identifier not the build type (i.e. devedition-gitunstable not unstable)|
 |BIOS|Modifies the system to boot in BIOS mode instead of UEFI (our tooling only). In os-auto-inst this var is `UEFI` and inverted.
 |SECUREBOOT|Modifier for INSTALLATION to run in secureboot (gets bootstrapped before ISO starts)|
 |INSTALLATION_OEM|Modifier for INSTALLATION to run in OEM mode|
 |OEM_USERNAME|User name to use for the temporary oem user (i.e. the user the vendor uses to configure the system)|
 |OEM_PASSWORD|Password of the oem user|
 |OPENQA_APT_UPGRADE|Can be a space separated list of packages or `all` to do a dist-upgrade|
 |OPENQA_INSTALLATION_OFFLINE|Modifier for INSTALLATION to switch networking offline before starting the install|
 |OPENQA_INSTALLATION_NONENGLISH|Modifier for INSTALLATION to test install in Spanish|
 |OPENQA_IN_CLOUD|Set by CI nodes. Used internally to optimize perform for builds on some cloud server (e.g. use apt mirrors for speed)|
+|OPENQA_IN_CLOUD|Set by CI nodes. Used internally to optimize perform for builds on some cloud server (e.g. use apt mirrors for speed)|
+|OPENQA_SNAP_NAME|For snap testing this sets the application snap name. This is also the name that will be passed to `snap run`|
+|OPENQA_SNAP_CHANNEL|For snap testing this sets the store channel snaps are pulled from|
+|OPENQA_SNAP_RUNTIME_CHANNEL|For snap testing this sets the store channel the snap runtime (kde-frameworks-5) is pulled from. If this is not set OPENQA_SNAP_CHANNEL will be used. If that isn't set either, the stable channel is used instead|
 
 # Test Suites
 
 Suites are more or less hardcoded variants of a suite comprised of multiple
 tests. Suites are generally mutually exclusive.
 
 |Variable|Description|
 |--------|-----------|
 |INSTALLATION|Test group. Conduct an installation test. Requires a TYPE to decide which ISO to install|
 |PLASMA_DESKTOP|Test group. Core Plasma behavior|
 |TESTS_TO_RUN|Colon separated list of test files to run (e.g. `tests/install_ubiquity.pm:tests/plasma_folder.pm`). Only used unless a test group is set.|
+|OPENQA_SNAP_NAME|Basename of a snap-only test. This test needs to be in the `tests/snap/` directory. This can be a specific testfile, e.g. `okular.pm`, if none exists `generic.pm` will be used instead. This variable is also a test variable (see above)|
