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

Hi IronRuby mailing list,

Inspired by a talk by Ben Hall on testing c# with Ruby I thought I''d
give it
a go but
I''m frustratingly stuck at the first hurdle. I''ve emailed Ben
but as I''ve
not had an immediate response I thought I''d open it to you good people.

Any way. I thought I''d start off simple and follow Dom Green''s
blog.
domgreen.com/2010/02/07/pumping-iron-ruby-net-testing/

He''s set a class in c# with a simple property (here''s mine)

namespace IronRubyAndCSharp
{
    public class Person
    {
        public string FirstName { get; set; }

        public Person(string name)
        {
            FirstName = name;
        }
    }
}

and tested it like so

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",Person.FirstName)
  end
end

RubyMine(RM) has no problem with the require of the dll but it does have a
problem recognising the namespace "IronRubyAndCSharp"
and the Person class (squiggly lines ahoy).

When I run the tests in RM I get

NoMethodError: undefined method `FirstName'' for
IronRubyAndCSharp::Person:Class
C:/Users/John/Documents/IronRuby/Tests/Person_test.rb:14:in
`test_create_person_called_john''

    C:/Program Files (x86)/IronRuby
0.9.4.0/Lib/ruby/1.8/test/unit/autorunner.rb:12:in `run''

Just in case RubyMine was at fault I dropped out to good old ir.exe

C:\Users\John\Documents\IronRuby\Tests>ir Person_test.rb --name
test_create_pers
on_called_john
Loaded suite Person_test
Started
E
Finished in 0.041992 seconds.

  1) Error:
test_create_person_called_john(PersonTest):
NoMethodError: undefined method `FirstName'' for
IronRubyAndCSharp::Person:Class
    Person_test.rb:14:in `test_create_person_called_john''
    :0:in `send''
    :0:in `each''
    :0:in `each''
    testrunner.rb:66:in `start_mediator''
    testrunnerutilities.rb:28:in `run''

1 tests, 1 assertions, 0 failures, 1 errors

I''ve stuck my code up on github
http://github.com/johnnonolan/IronRubyAndCSharp if you feel that was
inclined.

Any pointers, help or whatever much appreciated.

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
