Not sure what those functions are used or intended for - I cannot see
any invocation of them.

This increment is too much. But you do not need to count manually
because you can get the count directly via args.size.

Well, if you want to do that just include those calls in the script:
test(a,b,c)
test("yoyo", "yaya")

If you want to find out the arguments to the program, then this is easiest:
puts "You called me with #{ARGV.size} argument(s) as parameters"
Then just invoke it with
$ ruby your-script.rb arg1 arg2
If you want to use your method #test to evaluate program arguments you can do
test(*ARGV)
But I am not 100% sure I understood what you're after.
Kind regards
