FactoryBot and Faker

Configure FactoryBot

Create spec/support/factory_bot.rb.

mkdir spec/support
touch spec/support/factory_bot.rb

Add the following blurb in that file to configure FactoryBot.

# spec/support/factory_bot.rb
require 'factory_bot'

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

Add the following to your rails_helper.rb file...

require 'spec_helper'

# NOTE -- you need to require factory bot AFTER spec_helper
require 'support/factory_bot'

# ...
ENV['RAILS_ENV'] ||= 'test'

Configure Faker

Create spec/support/faker.rb

touch spec/support/faker.rb

Paste in the following contents...

require "faker"
Faker::Config.locale = 'en-US'

Now add require 'support/faker' to your rails_helper.rb after the require for FactoryBot.
