Rails 3.2, RSpec, Factory Girl : NameError: uninitialized constant Factory

Question

Ive been following this introductory to Rails testing and Ive run into an issue I cant seem to find the solution to. Im very familiar with Rails but this is my first foray into testing.

Anyhow, I have a very basic model test, not even fully implemented and when I try and run rspec spec/models/admin_spec.rb. I get the following error in the Admin has a valid factory line (full code below)

Admin has a valid factory
 Failure/Error: Factory.create(:admin).should be_valid
 NameError:
   uninitialized constant Factory
 # ./spec/models/admin_spec.rb:6:in `block (2 levels) in <top (required)>'

I assume FactoryGirl isnt being loaded for some reason but I was under the impression it should be automatically loaded. Below is the full code from my Gemfile, /spec/models/admin_spec.rb and /spec/factories/admins.rb

Thanks very much for your help

Answer 1

It should be FactoryGirl.create instead. Apparently Factory was deprecated and now has been removed, look at the comments in the link you provided :)

ahhh sigh. Haha, thanks very much. I did a find on the page for the "uninitialized constant Factory error" but didn't read close enough. I got the feeling it'd be something simple. Thanks again. – Skimp

Answer 2

In fact in your spec_helper.rb under Rspec.configure do...end you can add

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
end 

This will save you the trouble of the prefixing FactoryGirl. before :build and :create altogether:

require 'spec_helper'

describe Admin do
  it "has a valid factory" do
    create(:admin).should be_valid
  end
  it "is invalid without a name"
  it "is invalid without an email"
end

Answer 3

This isn't an answer to your question, but I noticed there is an obscure error in your use of Faker with FactoryGirl. f.name and f.email will be the same for every FactoryGirl.create or FactoryGirl.build.

f.name Faker::Name.name
f.email Faker::Internet.email

Add curly braces around the Faker calls so that each reference to a Factory will generate random Faker data.

f.name { Faker::Name.name }
f.email { Faker::Internet.email }

Ah yup, I did catch that one later on, while I was reviewing my code, but thanks for the heads up anyhow. – Skimp

Thank you for this! Stupid mistake but easy to miss – Marella

Answer 4

Also, be sure that you are including the require statement in your spec_helper.rb file.

require 'factory_girl_rails'
