Topic: Agile Web Development with Rails, 3rd Edition / RSpec ?

I would love RSPEC inclusion, but it seems like Shoulda would be a good fit since it extends Test::Unit. Is test/spec under development? I thought it was halted as the author worked on a new bdd testing package.

Thanks I’ll give it a whirl.

Topic: Advanced Rails Recipes / Should Recipe and Postgres

Mike,
It didn’t run a regular test so I checked out AWDR2 to see what I was doing wrong in the regular test. Then I noticed:

require File.dirname(__FILE__) + '/../test_helper'
class EventTest < Test::Unit::TestCase
#code
end

the require was missing and that was it. That might be worth mentioning in the recipe.

I went on to try more of the recipe. I coded up the shoulda spec and the model, but now I’m getting additional problems.

require File.dirname(__FILE__) + '/../test_helper'

class EventTest < Test::Unit::TestCase
  should_require_attributes :name, :description,:image_location,
                            :starts_at, :location, :capacity
  should_require_unique_attributes :name
  should_only_allow_numeric_values_for :price
  should_not_allow_values_for :price, -1.0, :message => /must be greater than or equal to 0/
  should_have_many :attendees, :through => :registrations
end

class Event < ActiveRecord::Base
  validates_presence_of :name, :description, :image_location, 
                        :starts_at, :location, :capacity
  validates_uniqueness_of :name

  validates_numericality_of :price , :greater_than_or_equal_to => 0.0

  has_many :registrations
  has_many :attendees, :through => :registrations,
                       :source => :user
end

It seems, however, that there is a requirement that some objects already exist to test those. I’ve tried it with bot 3.0.4 of shoulda and the current version and get the same results.

Mike, Thanks for the reply.

Here is all I have

class EventTest < Test::Unit::TestCase
  should_require_attributes :name, :description,:image_location,
                            :starts_at, :location, :capacity
#  should_require_unique_attributes :name

#  should_only_allow_numeric_values_for :price

#  should_not_allow_values_for :price, -1.0, :message => /must be greater than or equal to 0/

#  should_have_many :attendees, :through => :registrations

end

Topic: Advanced Rails Recipes / Should Recipe and Postgres

Hello,
I just tried the Shoulda Recipe (51) with Rails 2.0.2 and Postgres (8.1 on windows, 8.2 on Ubuntu) and I’m getting an error when I run the test.
I’m using a new rails application and the dev and test databases works (I did a migration and ran rake db:test:prepare to make sure).
I’ve tried this with both the version of shoulda in the recipe and the current version. And the only file I’ve created is the perscribed test/unit/event_test.rb

Any ideas?
