Summary:
I started out wanting to fix an issue I noticed today where
graphical upgrade tests were failing because they didn't wait
for the graphical login screen properly; the test was sitting
at the 'full Fedora logo' state of plymouth for a long time,
so the current boot_to_login_screen's wait_still_screen was
triggered by it and the function wound up failing on the
assert_screen, because it was still some time before the real
login screen appeared.
So I tweaked the boot_to_login_screen implementation to work
slightly differently (look for a login screen match, *then* -
if we're dealing with a graphical login - wait_still_screen
to defeat the 'old GPU buffer showing login screen' problem
and assert the login screen again). But while working on it,
I figured we really should consolidate all the various places
that handle the bootloader -> login, we were doing it quite
differently in all sorts of different places. And as part of
that, I converted the base tests to use POSTINSTALL (and thus
go through the shared _wait_login tests) instead of handling
boot themselves. As part of *that*, I tweaked main.pm to not
require all POSTINSTALL tests have the _postinstall suffix on
their names, as it really doesn't make sense, and renamed the
tests.
Test Plan: Run all tests, see if they work.

use 'ps' output for Xorg and Xwayland. We'd need some new
openQA var to get this right by 'guessing', as it's vt1 for
Workstation when running live - so long as autologin worked -
but vt2 after install. We'd need a var or some other thing to
detect which case we're running in. LIVE doesn't do it, it's
set even when running a post-install test from a live image.
So instead let's just do it a bit more cleverly. This also
gives us a bit of insurance against changes in GDM, SDDM etc.
behaviour, so long as Xwayland or Xorg is running (and we can
add additional processes to the list, like gnome-shell, if
needed/appropriate). We assume the *final* listed process -
i.e. the most recently-started one - will be the desktop;
this covers gdm's behaviour of starting up on vt1 then running
the user session on vt2. We can make this function more complex
and add args if we ever get to the point where we have multi-
user tests running or anything (e.g. allow to pass a username
and only look for that user's processes).
Landing without review as this broke the live variant of the
test on Workstation in production (kinda not sure why it worked
in testing, or I didn't notice that it failed, but never mind).
I've tested it on staging.
Summary:
the main thing this does is try and type slower in X - this
should cover nearly everywhere we type anything in X, and make
it type slower. We also add a bit more safety checking to some
old tests which didn't have it (mainly _do_install_and_reboot)
- wait_still_screen after typing to make sure all the keypresses
were registered before continuing.
This is an attempt to mitigate the problems we've seen where
the wrong text gets typed into the wrong places and the tests
break.
This branch is live on staging atm. It still has *some* issues,
but I do think it's an improvement.
Test Plan:
run the tests (probably several times), compare to
runs without the change, see if it's better or worse...
