NameError: uninitialized constant Factory

Question

I'm following this tutorial to get started with TDD on rails with factory girl, rspec and i ran into this issue i can't get my head around.

Here's my "factory".rb (events.rb)

require 'faker'

FactoryGirl.define do
   factory :event do
     name "HIGH"
     genre "house, techno, idb"
     venue_name "Westbourne Studios"
     venue_address "4-6 Chamberlayne Road"
     venue_postcode "NW103JD"
     begin_time "10pm"
     end_time "2am"
     user_id 2
     description "A Super massive party with loads of everything you would want around."
     status true
     venue_id nil
   end
end

and here's the event_spec.rb:

require 'spec_helper'
require 'factory_girl_rails'

describe Event do

it "has a valid factory" do
  Factory.create(:event).should be_valid
end

  it "is invalid without a name"
  it "is invalid without a genre"
  it "is invalid without a venue_name"
  it "is invalid without a venue_address"
  it "is invalid without a venue_postcode"
  ...

 end

I have setup the model, migrated etc.. and when i run "rspec spec/models/event_spec.rb" i get the following error:

Failures:

1) Event has a valid factory
 Failure/Error: Factory.create(:event).should be_valid
 NameError:
   uninitialized constant Factory

Answer 1

Try to use it in this way:

FactoryGirl.create(:event).should be_valid

I think, I can remember, that it was only "Factory" in old versions of the gem. If you take a look in the recent "Getting started" guide of Factory Girl, there are only calls with "FactoryGirl".

Answer 2

If you create file spec/support/factory_girl.rb with content:

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

Then you can simply use:

create(:event)
build(:book)

Instead of:

FactogyGirl.create(:event)
FactogyGirl.build(:book)

I had the same error with factory bot, and to supplement Stefan's answer I came across this little cheat sheet.
