Sidenote: With modern Git (>= 1.6.6), you are able to use just
git checkout test
(note that it is 'test' not 'origin/test') to perform magical DWIM-mery and create local branch 'test' for you, for which upstream would be remote-tracking branch 'origin/test'.
The * (no branch) in git branch output means that you are on unnamed branch, in so called "detached HEAD" state (HEAD points directly to commit, and is not symbolic reference to some local branch). If you made some commits on this unnamed branch, you can always create local branch off current commit:
git checkout -b test HEAD
