Only the dot files? Not all of the files? Why not all of the files?

Since "*" matches "." that ".*" also matched "..". Having matched
".." it was recursing down the entire /home directory. I am assuming
you have repaired that problem already by setting the other directory
ownerships back to what they needed to be already.

Better would have been:
ls -d /home/test/.* | less

Use find for this. It is perfect.
find /home/test/ -exec chown test:test {} +
But if you really want to use 'chown -R' then just using it by itself
is fine. Just don't use any shell wildcards.
chown -R test:test /home/test/
If you want the bash way for matching characters that are not a dot:
chown -R test:test /home/test/.[!.]*
You can test the match out using 'ls' before running the chown.
ls -d /home/test/.[!.]* | less
