Hello Ruby fan
That is first time which I into forum
A question places a test environment for a program must provide
Here is program now test the program

#!/usr/bin/env ruby

class MYAPPException < Exception
end
class MYAPPGood < Exception
end


class Test
    def initialize( arg)
        begin
            $stdout.print "\nProgram 1 check Argument size from #{arg}"
            check(arg)

        rescue MYAPPException =>str
            $stdout.print "\nException output"
            $stdout.flush
            $stdout.print "\nError : #{arg} ",$!

            exit(-1)
        else

            exit(0)
        end
    end
    def check(str)
        $stdout.print "\nin check Method #{str.to_s.size} #{str.class}"
        if str.size<=5
            $stdout.print "\ncheck to short"
            raise MYAPPException,"Input to short"
        end
        if str.size >=10
            $stdout.print "\ncheck to long"
            raise MYAPPException,"Input to long"
        end
        $stdout.print "\nresult : ",str
        $stdout.print "\ncheck okay"
    end
end
if  __FILE__ == $0
    t=Test.new(ARGV[0])
end


In the case I have to indicate specially an error to 4

#!/usr/bin/env ruby
#require "program1.rb"

require "test/unit"

class Cmdline_Tests < Test::Unit::TestCase

    def test_Progam1
    #No.1
        a = %x[ruby Program1.rb 123]
        assert_equal(255,$?.exitstatus )
        assert_match(/Input to short$/,a)
    #No.2
        a = %x[ruby Program1.rb 1234567890]
        assert_equal(255,$?.exitstatus )
        assert_match(/Input to long$/,a)
    #No.3
        a = %x[ruby Program1.rb 1234567]
        assert_equal(0,$?.exitstatus )
        assert_match(/check okay$/,a)
    #No.4
        a = %x[ruby Program1.rb 1234567]
        assert_equal(0,$?.exitstatus )
        assert_match(/check okayy$/,a)
    end
end

inserted around my question clearly
