Almost. See comment below.

Almost. See comment below.

Oops, I'm mistaken here. The directory shall be called dbus-resources,
see .../test/file-organization.org. Sorry.

I'd vote for the latter, with the first argument :session preceding
the other arguments in the same line. Like
(let* ((property
(dbus-introspect-get-property
:session dbus--test-service
dbus--test-path interface property-name)))
...)
If all arguments fit into 80 columns, do it.
The "canonical" formatting is offered by the `pp' command (pretty
printer). I must confess, that I do not follow all its recommendations.

No, the former is OK. People might want to use it in their packages.

I see. Will investigate.
And now my review for the latest patch versions.

If you have one comment for several functions, use only one parenthesis
per line like
(dbus--test-run-property-test, dbus--test-property)
(dbus-test06-property-types): Test property registration, set, get.

If a cons cell doesn't fit into one line, you shall move the dot "." to
the beginning of the next line, like
(dbus--test-property
"ObjectArray"
'((:array
:object-path "/node00"
:object-path "/node01"
:object-path "/node0/node02")
. ("/node00" "/node01" "/node0/node02"))
I bet the dot "." has the font-lock-warning-face (red foreground color)
in your buffer. Admittedly, it doesn't look prominent :-(
Move the cursor over the misplaced dot; there shall be a help message about.

I don't believe we need this message. We see that we're done :-)

That's not true. All but the last functions are new defuns, not new
tests. And please start the explanation with a capital letter, like "New test."

The docstring line does not fit 80 chars. What about
"An annotation indicating a deprecated interface, method, signal, or property."

As said, it must be "dbus-resources".

:tags must be after the docstring.
