Subject: test/unit question

I am learning to use test/unit framework included in ruby 1.7.3 (2002-11-17)
[i386-mswin32]
So downloaded the latest relase of Test::Unit.
Here is my first attempt which does not work :-(|
Please help!

class Find_Matching

    def initialize(lyst)
        p lyst if $DEBUG
        @lyst = lyst
    end

    def  find_matching_paran(from=0)
    # finds the position of  a closing paranthesis in the list/array for the
opening paran at 'from'
        puts 'from = ' + from.to_s if $DEBUG
        list = @lyst.slice(from..-1)
        p list if $DEBUG
        m = level = 0
        if (list[0] == '(')
            list.each_index { |i|
                level += 1 if (list[i] == '(')
                level -= 1 if (list[i] == ')')
                (m = i; break) if (level == 0)
            }
