when I run the following code

require 'test/unit'
class TC_Pram < Test::Unit::TestCase
  def initialize(name)
    @name=name
  end
  def test_array
     puts assert_equal(2,@name[2])
  end
end
tc=TC_Pram.new("wang")
tc.test_array

there are some errors as follows

c:/ruby/lib/ruby/1.8/test/unit/testcase.rb:125:in `add_assertion':
undefined method `add_assertion' for nil:NilClass (NoMethodError)
 from c:/ruby/lib/ruby/1.8/test/unit/assertions.rb:494:in

 from c:/ruby/lib/ruby/1.8/test/unit/assertions.rb:83:in

 from test_unit.rb:7:in `test_array'

require 'test/unit'

class TC_Pram < Test::Unit::TestCase
   def setup
     @name = "wang"
   end

   def test_array
     assert_equal ?n, @name[2]
   end
end

nothing more. don't add puts. don't instantiate or call the method.
just run it with ruby. "require 'test/unit'" will take care of the rest.

I changed your assertion so that it'll pass. you may not have wanted
that.
