The background color of the generic left bar needle has changed
to match the new logo base color. The top bar's background color

top bar, just solid electric blue. This needle matches that.

KDE update was still often failing on #1943943, so this tries a

either change may be helping. Either way, this does make the test

KDE in F34+ is now placing sleep, restart and shutdown buttons
right on the system menu, not in a submenu. So we need to sort of
tweak this logic. The approach here is: we count the GNOME
submenu as both a "power" and "leave" menu, so the needle to
enter it has both tags. KDE still has a "leave" submenu, but the
power options are not in a submenu any more, so the new "leave"
needle only has the leave tag, not the power tag. For "leave"
actions we just unconditionally expect the "leave" tag; for
power actions we first match on *either* the submenu tag (for
GNOME and earlier KDE) *or* the action tag, click whatever we
found, and then if we matched the submenu (not the action), we
assert and click the action. After that all paths should be in
sync again and we can continue.

There's a race issue with just treating it as a next button: it's

place, but if we click "Start Setup" in the middle of transition
to the Privacy screen - as in

This is the best option I can come up with to deal with #195.
Update notifications seem to have become transient in KDE lately
(even in F31 and F32, if I'm looking at these screenshots right).
This actually simplifies things a lot to do more or less the
same in the KDE and GNOME paths: open the 'permanent' store of
notifications (in GNOME you get to it by clicking on the clock,
in KDE via the systray) and then look for no notifications (live
path) or only an update notification (post-install path). We
only run this test for composes so we shouldn't need to worry
about anything older than F32, and I believe this should work
for KDE in F32 and F33. I left out click_unwanted_notifications
for now as I'm hoping it should be unnecessary, but we can add
it back in if necessary.

This is a bit complex to automate, because we cannot really use
the production Zezere server (provision.fedoraproject.org) as
the test case shows, as we'd have to solve authentication and
we also don't really want to constantly keep registering new
hosts to it that are going to disappear and never be seen again.
So, instead we'll do it by setting up our *own* Zezere, and
provisioning our IoT system in that. We run two tests. The
'ignition' test is the actual IoT 'device'; all it really does
is boot up, sit around, and wait to be provisioned. The 'server'
test first sets up a Zezere server, then logs into it, adds an
ssh key, claims the IoT device, provisions it, and connects to
it to create a special file which tells the 'ignition' test
everything worked and it can close out.

Since GDM shows the "system-menu-button", it could not correctly
switch users on a locked screen. I added a check to see
if we are on a locked screen and behave accordingly.
This adds a new test that implementsQA:Testcase_desktop_login
on both GNOME and KDE.
While working on this, we realized that the "desktop_clean"
needles were really "app menu" needles, and for KDE, this was
a duplication with the new "system menu" needles, because on KDE
the app menu and the system menu are the same. So I (Adam)
started to de-duplicate that, but also realized that "app menu
button" is a much more accurate name for these needles, so I was
renaming the old desktop_clean needles to app_menu_button. That
led me to the realization that "check_desktop_clean" is itself a
dumb name, because we don't (at least, any more, way back in the
mists of time we may have done) do anything to check that the
desktop is "clean" - we're really just asserting that we're at a
desktop *at all*. While thinking *that* through, I *also* realized
that the whole "open the overview and look for the app grid icon"
workaround it did is no longer necessary, because GNOME doesn't
use a translucent top bar any more. That went away in GNOME 3.32,
which is in Fedora 30, our oldest supported release.
So I threw that away, renamed the function "check_desktop",
cleaned up all the needle naming and tagging, and also added an
app menu needle for GNOME in Japanese because we were missing
one (the Japanese tests have been using the "app grid icon"
workaround the whole time).
This adds a needle for the 'day' background from 32.1.1, which
is the non-animated default, and renames the needle for the
background from 32.0.0 to 'old' as it's no longer present at all
in the new build. Depending on whether animation actually works
after the update we may later need to add needles for the other
images plus possibly some transition needles too. Sigh.

I call this...The @lruzicka Catcher!
It's a script that checks for needles that aren't actually used
anywhere. It also checks for cases where we have a needle JSON
file but no image, or an image file but no JSON file (and wipes
one case of the latter). It also adds a run of the script to tox
so we get it in CI.
You could make this script a lot more elaborate if you like, by
being fancier about parsing the test code and templates, but I
don't think it's really warranted, I think it just needs to be
'good enough'. It's not the end of the world if it misses the
odd thing or the whitelisting goes stale.
Quite a lot of the removed needles are remnants of different
approaches to app start/stop testing which weren't caught in the
initial PR review. The short-name partitioning ones are odd; they
were introduced in the commit that moved needles into subdirs,
but at least some of them don't actually appear to be moves. They
may have been non-tracked files Josef had lying around that got
into the commit by mistake, or they may just be old needles we
really used at some point but aren't using any more.
reclaim_space_second_partition was introduced as part of the
shrink test (along with reclaim_space_first_partition) but was
never actually used by that test - I guess, again, the test got
re-written during review but we forgot to remove the needle. We
rejigged user creation to use tab presses not a needle match a
while back, which made user_creation_password_input unnecessary.
The various cockpit_updates_* needles are I think remnants of
rewrites of the cockpit update tests that again were missed in
PR review, the tests as merged never used them.

for 'spurious auth prompt appears on desktop after you switch
away to a VT and back' out of the desktop update test and into

it as well. We enhance _graphical_wait_login to handle the boot
loader if needed (it has never needed to until now).
