Rather than *reall* sending mail here, we instead have a new test
program, smtp-dummy which implements (a small piece of) the
server-side SMTP protocol and saves a mail message to the filename
provided. This gives us reasonable test coverage of a large chunk of
the notmuch+emacs code base (down to talking to an SMTP server with
the final mail contents).
If Xapian sees unquoted ".." as in id:123..456 then it thinks that's a
range specification. We avoid this problem by instead passing
id:"123..456" to Xapian.
We simulate the act of selecting the "inbox" saved search from
notmuch-hello and the act of selecting a desired thread from the
notmuch-search results.
The test for the navigation of notmuch-hello is currently marked as
BROKEN since its output is in the opposite order compared to the
'(notmuch-search "tag:inbox")' test. This question of ordering is a
currently open issue on the notmuch mailing list, so we'll let the
test suite reflect that for now.
Finally, this commit also abstracts some common emacs lisp code,
(waiting for the current buffer's process to complete), into a new
notmuch-test-wait function that is made available to anything calling
test_emacs.
