/usr/bin/test not working

I tried:

$ test -r somefile.jpg
$ test -w anotherfile.txt
$ test --help

And nothing happens.

Also:

$ cd /usr/bin/
$ ./test --help

Yields nothing.

Please advice?

From the manpage:

NOTE: [ honors the --help and --version options, but test does not. test treats each of those as it treats any other nonempty STRING.

test only sets the exit status of the command. It doesn't print anything. You can echo $? to see the status.
