Subject: using testrb

My script _works_ but testrb is giving me some error messages. I've just come across unit testing yestarday so I'm quite new to this. What do these error messages mean and why does the script not run?


A sample script:-

jayeola@acid$ cat fact.rb 
def fact(n)
  return 1 if n == 0
  f = 1
  n.downto(1) do |i|
    f *= i
  end
  return f
end
print fact(ARGV[0].to_i), "\n"

sample usage:-
jayeola@acid$ ruby fact.rb 44
2658271574788448768043625811014615890319638528000000000

using testrb:-

jayeola@acid$ testrb ruby fact.rb 4
