That's what I mean. For some tests, we do want trailing whitespace. For
some - not. Imagine that we decide to change the test failing due to
whitespace cleanup, but leave your proposed test. Then, your test may be
failing, and it will be rather difficult to figure out why.

Not sure what you mean by that, but some tests rely on trailing spaces
and fail when these are not present.  An explicit test on that would
make the issue more visible.  See below for what I mean.  The only (?)
downside is that this catches such errors in test-org.el only, and not
in all the other tests, many of which also contain (on purpose or
inadvertently) trailing whitespace:

Never mind. This will not affect deleting empty lines that are not
at the end of buffer.

There is no universal rule when and when not to add trailing spaces in
the tests.

What we can do is setting `delete-trailing-lines' to nil in tests - via
directory-local variable.

Not a bug, my bad:  I keep forgetting about `delete-trailing-whitespace'
on my `before-save-hook'.

Would you mind if I added a test that explicitly and with some nice
error message tests for that condition?  I.e. if some unwary user
strips off trailing whitespace in test-org.el, that test would fail
with a reasonable message.

I cannot reproduce on my system. Using Emacs 29.
Our CI tests are also not failing.
