If the server is too slow, changing to a different file immediately
after sending a new comment but without waiting for the comment to be
shown for the original file could cause the new comment to be shown for
the current file instead.
This is, indeed, a bug in the comments. However, it is not possible to
test it reliably in the acceptance tests, as it depends on how fast the
server adds the message and how fast the client changes to a different
file; sometimes the test would fail and sometimes it would not.
Therefore, now it is waited for the comment to be added before changing
to another file, as in this case it can be reliably tested that changing
to a different file does not cause the comments from the previous file
to be shown in the current file (this was a different bug already fixed
and due to which this test was added in the first place).

When the "Comments" tab is open the empty content element is always in
the DOM, although it is only shown once the message collection was
fetched and there were no messages. Due to this it is necessary to
explicitly wait for it to be shown instead of relying on the implicit
wait made to find the element; otherwise it would be found immediately
and if the collection was not fetched yet it would not be visible,

In the acceptance tests the link share menu is automatically opened if
needed before interacting with an item in the menu; if the menu is not
open it is opened by clicking on its toggle.
However, since a recent change the link share menu is automatically
opened by the regular UI after the link share is created. This causes
that, sometimes, after the creation of a link share the acceptance tests
check whether the menu is shown or not before the menu was automatically
opened; as the menu is not open then the acceptance tests proceed to
click on the toggle, but in the meantime the link share was created and
the menu opened, so clicking on the toggle now closes it. As the menu is
closed it is not possible to interact with its items and the test fails.
To prevent that now the acceptance tests wait for the link share menu to
open after a link share is created before continuing with the other
steps.

The update share tests only checked that the share returned by
"update()" had the expected values. However, as "update()" returns the
same share that was given as a parameter the tests were not really
verifying that the values were updated in the database.
In a similar way, the test that checked that a password was removed did
not set a password first, so even if the database returned null it could
be simply returning the default value for the share; a password must be
set first to ensure that it is removed.
Besides that, a typo was fixed too that made the checks on the original
share instead of on the one returned by "update()"; right now it is the
same share, so the change makes no difference, but it is how the check
should be done anyway.

The PHP built-in server can crash when certain actions are performed in
Nextcloud (but although the crash is triggered by Nextcloud it does not
seem to be a Nextcloud bug), which can lead to failures in the
acceptance tests that would have otherwise passed.
A crash of the PHP built-in server during an acceptance test can be
identified by the message "sh: 1: kill: No such process" in the
acceptance tests output; as the PHP built-in server crashed its process
does no longer exist when it is tried to be killed when the scenario
ends.
Although the crash has been observed in other tests too it is more
prevalent in the tests for tags and the theming app. In order to
reduce the false positives those tests are now run on Apache instead of
on the PHP built-in sever. However, the rest of tests are still run on
the PHP built-in server due to its lower resource consumption.
In order to run a feature or just a scenario using Apache it has to be
tagged with "@apache"; features or scenarios without that tag (the
default) will run on the PHP built-in server instead.

the linking was moved from "run.sh" to "run-local.sh", so it is
automatically done when run through "./run.sh" and in Drone, including
when running the tests for an app instead of for the server.

Each time a new actor appears in a scenario the browser window of the
new actor is put in front of the browser windows of the previous actors.
Before, when acting again as a previous actor his browser window stayed
in the background; in most cases everything worked fine even if the
window was in the background, but due to a bug in the Firefox driver of
Selenium and/or maybe in Firefox itself when the window was in the
background it was not possible to set the value of an input field that
had a range selected.
Now, when acting again as a previous actor his browser window is brought
to the foreground. This prevents the bug from manifesting, but also
reflects better how a user would interact with the browser in real life.

This also applies if `https://nextcloud.example.com/` sends the `Clear-Site-Data: "cookies"` header.

Before each scenario of the acceptance tests is run the Nextcloud server
is reset to a default state. To do this the full directory of the
Nextcloud server is commited to a local Git repository and then reset to
that commit when needed.
Unfortunately, Git does not support including empty directories in a
commit. Due to this, when the default state was restored, it could
happen that the file cache listed an empty directory that did not exist
because it was not properly restored (for example,
"data/appdata_*/css/icons"), and that in turn could lead to an error
when the directory was used.
Currently the only way to force Git to include an empty directory is to
add a dummy file to the directory (so it will no longer be empty,
but that should not be a problem in the affected directories, even if
the dummy file is not included in the file cache); although Git FAQ
suggests using a ".gitignore" file a ".keep" file was used instead, as
it conveys better its purpose.
