You don't need NIS to test it because you can add netgroup entries in
a file called /etc/netgroup.  I don't have a script handy to create
these, but the netgroup manpage[1] should help you with the netgroup
file format to come up with one.  The file format is quite simple
actually.  Each netgroup entry is of type:

netgroup_name (host1, user1, domain1) (host2, user2, domain2) ...

where the stuff in brackets is called a triplet, which specifies a
combination of hostname, username and domain name that may be allowed
in a netgroup.  A netgroup entry can be split into multiple line with
a trailing backslash (\).  One may have wildcards in a triplet like

(host1, , domain1)

This means any user on host1 and domain1.  You can have similar
wildcards for hosts and domains as well, which makes all of the
following as valid triplets:

(, user, domain)
(, , domain)
(host, , domain)
(host, , )
(host, user, )

and so on.  

I hope this helps.
