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
