There is a defect which is involved here, and probably interferes:

http://trac.nginx.org/nginx/ticket/97

Anything involving try_files and alias may not do what you expect.

If you can specify what exactly you want, it may be possible to find a
configuration which does that using the current implementation of the
defect. Or it may not be.

You will probably be much happier investigating if you enable the
debug log.

Can you tell whether the 404 is from the uri argument of try_files,
or the serve-from-filesystem handler?

Look in the debug log and you will see what happens.

Or: what do you see if you change try_files to end in =405?

The rest is "the details of what else try_files and alias do".

(try_files does see /test/test.html, but the serve-from-filesystem
handler does not try to serve that file.)
