This is a design "feature" in emacs (and most of the Windows editors as
well). None of them write files in-place. What they do is create a copy
of the file with the changes from the editing session. The inode is also
changed (easy to check), so what you're seeing is a brand new file. The
old one, IIRC, is renamed to "test~" (I don't use emacs, so can't check).
This, BTW, is one of the reasons you can't use emacs as crontab editor, or
anything else that expects the file to be written in-place.

P.S. I think I'm being a bit unfair ("I'm a VIm guy"), and you *can*
configure emacs to write files in-place -- it's just not done by default.
