## Test suite description
Maintainer: qsf-y

Test for yast2 UI, GUI only. Running on created gnome images which provides
both text console for ncurses UI tests as well as the gnome environment for the
GUI tests.

Temporarily added YAST2_GUI_TERMINATE_PREVIOUS_INSTANCES to see if helps. This
variable triggers code which terminates all yast2 processes before starting new
one. (see poo#26104).


## Reproducible

Fails since (at least) Build
[20200728](https://openqa.opensuse.org/tests/1346327)


## Expected result

Last good: [20200727](https://openqa.opensuse.org/tests/1345093) (or more
recent)


## Further details

Always latest result in this scenario:
