[Ironruby-core] Getting started with IronRuby and c# issues.

ironruby will have 'rubified' the Person class's FirstName method to
first_name and I think you mean to assert against the john instance of
Person (rather than the Person class).

Otherwise it looks pretty close.

Try:

require "test/unit"
require "../IronRuby/bin/debug/IronRubyAndCSharp.dll"

class PersonTest < Test::Unit::TestCase
include IronRubyAndCSharp
 def test_create_person_called_john
   john = Person.new("John")
   assert_not_nil(john)
   assert_equal("John",john.first_name)
 end
end
