Rspec new expectation syntax - rspec2

Question

I've the following rspec unit test:
require 'spec_helper'
describe Article do
describe ".recents" do
it "includes articles created less than one week ago" do
article = Article.create(created_at: Date.today - 1.week + 1.second)
expect(Article.recents).to eql([article])
end
it "excludes articles published at midnight one week ago" do
article = Article.create!(:created_at => Date.today - 1.week)
expect(Article.recents).to be_empty
end
end
end
and the Articlemodel:
class Article < ActiveRecord::Base
attr_accessible :description, :name, :price, :created_at
scope :recents, where('created_at <= ?', 1.week.ago)
end
when I run my tests I get:
1) Article.recents includes articles created less than one week ago
Failure/Error: expect(Article.recents).to eql([article])
expected: [#<Article id: 60, name: nil, description: nil, price: nil, created_at: "2012-11-14 00:00:01", updated_at: "2012-11-21 10:12:33", section_id: nil>]
got: [#<Article id: 60, name: nil, description: nil, price: nil, created_at: "2012-11-14 00:00:01", updated_at: "2012-11-21 10:12:33", section_id: nil>]
(compared using eql?)
Diff:#<ActiveRecord::Relation:0x007ff692bce158>.==([#<Article id: 60, name: nil, description: nil, price: nil, created_at: "2012-11-14 00:00:01", updated_at: "2012-11-21 10:12:33", section_id: nil>]) returned false even though the diff between #<ActiveRecord::Relation:0x007ff692bce158> and [#<Article id: 60, name: nil, description: nil, price: nil, created_at: "2012-11-14 00:00:01", updated_at: "2012-11-21 10:12:33", section_id: nil>] is empty. Check the implementation of #<ActiveRecord::Relation:0x007ff692bce158>.==.
# ./spec/models/article_spec.rb:7:in `block (3 levels) in <top (required)>'
Could someone please help me to figure out what's the error in my test?
It seems good for me.

Answer 1

You are comparing an activerecord relation (Article.recents) to an array ([article]), which is why the expectation is failing. (It looks like they are the same in the spec results because inspect converts the relation into an array before printing it out.)
Change your first expectation to this:
expect(Article.recents.to_a).to eql([article])
