Rails / Factory Girl: Uninitialized constant FactoryGirl (NameError)

Question

I installed the factory_girl gem, and when I run my tests I get an error:

`block in ': uninitialized constant FactoryGirl (NameError)

This is my spec_helper.rb

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end
  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end
end

How can it be fixed?

Solution 1

This must be your answer.

The required addition should be made in spec/support/factory_girl.rb

Solution 2

In spec/spec_helper.rb, try adding

FactoryGirl.find_definitions

under

require 'factory_girl_rails'

or make sure you follow factory_bot's Getting Started guide.

Solution 3

I'm just putting this here for anyone clumsy like me. Everything was fine, but I was calling FactoryGirl in one place, when I only have FactoryBot installed. Newbie error. Hope it might help.
