Re: [Emacs-diffs] master 81204b2: Port xref-tests to master branch

[Dmitry Gutov]

Does anyone have better suggestions than

(defvar xref-tests-data-dir
  (expand-file-name "../../data/xref/"
                    (file-name-directory (or load-file-name 
(buffer-file-name)))))

?

'cd test && make test-file-name' is handy, but it's not a full 
replacement: when running ERT interactively, you get niceties like being 
able to drop into the debugger right where a test fails.
