Getting started with IronRuby and c# issues

Ruby IronRuby

Hi IronRuby mailing list,

Inspired by a talk by Ben H. 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’

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

1 tests, 1 assertions, 0 failures, 1 errors

I’ve stuck my code up on github
GitHub - johnnonolan/IronRubyAndCSharp: Getting started with Ruby and CSharp 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
