Rails: Model Specification: Done 0

Posted by yrashk

I’ve moved my model specifications (like belongs_to, has_many, validates_ and friends) to RSpec specifications.

This was not very complicated. I admit that it is an early implementation with certain problems.

Please do not use this for anything except experiments. This solutions causes few problems that I haven’t fixed yet

Anyway, let me try to explain what I’ve done.

I rewrote spec/spec_helper.rb:

1

ENV["RAILS_ENV"] ||= "test"

case ENV['RAILS_ENV']
when 'test'
        require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
        require 'controller_mixin'
        require 'rspec_on_rails'

        class SpecTestCase < Test::Unit::TestCase
                self.use_transactional_fixtures = true
                self.use_instantiated_fixtures  = false
                self.fixture_path = RAILS_ROOT + '/spec/fixtures'

                # You can set up your global fixtures here, or you
                # can do it in individual contexts
                #fixtures :table_a, :table_b

                def run(*args)
                end

                def setup
                        super
                end

                def teardown
                        super
                end
        end

        module Spec
                module Runner
                        class Context
                                def before_context_eval
                                        inherit SpecTestCase
                                end
                        end
                end
        end

        Test::Unit.run = true
else
        class << self
                def context(name,&block) ; end
        end
end

Then, I’ve created has_specification (I have this script in lib/):

1

module ActiveRecord::Specification
        def has_specification
                unless ENV['RAILS_ENV'] == 'test'
                        require File.dirname(__FILE__)+"/../spec/models/#{self.to_s.tableize.singularize}_spec"
                end
        end
end

and surely added it to ActiveRecord::Base:



ActiveRecord::Base.extend ActiveRecord::Specification

Now, I was able to move all my specifications to spec/models/model_spec.rb. I did it by just adding something like

1
2
3

class Model < ActiveRecord::Base
 has_many :ideas
end

before specification contexts.

And, finally, I’ve replaced that specifications for app/models/model.rb with has_specification:

1
2
3

class Model < ActiveRecord::Base
 has_specification
end

It seems that it’s all.

I’m sure it could be done much better. But it’s a first quick hack solution to probe the idea, so please don’t beat me.

Was it a good idea at all? :)
