RSpec error "Uninitialized constant FactoryGirl (Name Error)"

Question

I try running my RSpec test:

rspec comments.rb

but keep getting the same error (see title). Before anyone asks I have already added require factory_girl to spec_helper.rb.

The contents of spec/factories/comments.rb file are:

  FactoryGirl.define do
    factory :comment do
      comment "MyString"
      task_id 1
  end
end

Here is testing group of the gemfile where I included factory_girl_rails:

source 'http://rubygems.org'

...

group :development, :test do
  gem 'debugger'
  gem 'factory_girl_rails'
  gem 'rspec-rails'
end

...

Solution

You just have to add the following in your spec_helper.rb file

require 'factory_girl_rails'

This answer uses the unknown constant FactoryGirl. How is this supposed to help?

I'm voting to delete this answer as it's not addressing the question that was asked.

FactoryGirl has changed its name to FactoryBot, so you will now need to use require 'factory_bot_rails'.
