Ruby Gem: Uninitialized constant FactoryBot

Working on a Ruby gem and trying to use FactoryBot inside with RSpec.

I have this in support/factory_bot.rb:

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

  config.before(:suite) do
    FactoryBot.find_definitions
  end
end

and in spec_helper.rb:

require 'support/factory_bot'

When I try to run the spec rake task, I get this error:

support/factory_bot.rb:2:in `block in <top (required)>': uninitialized constant FactoryBot (NameError)

What am I missing? This used to work fine when I was using the old factory_girl gem, but it has broken with the rename to factory_bot. Thanks!!

In my case I had to put those lines below 'require "rspec/rails" in file: spec/rails_helper.rb:

like:

require "rspec/rails"
require_relative "support/factory_bot"
require_relative "support/chrome"

I had this problem too, remove the

require 'support/factory_bot'

There's a line on rails_helper, just uncomment it:

Dir[Rails.root.join('spec', 'support', '**', '*.rb')].sort.each { |f| require f }

I had encountered and issue similar to this. I worked around it by removing the default testing suite ( MiniTest ). When you create a rails application and intend on using rspec and factory_bot, use the code below in the command line:

rails new myapp -T

Hope this helps xP

Overview just in case you are doing this from scratch

installation rspec details here (basically add gem to Gemfile then run bundle install)

initialize RSPEC in your rails project rails g rspec:install

create new file your spec/support/factory_bot.rb add the following base code:

require 'factory_bot'

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

# RSpec without Rails
RSpec.configure do |config|
    config.include FactoryBot::Syntax::Methods

    config.before(:suite) do
        FactoryBot.find_definitions
    end
end

add reference on spec/rails_helper.rb

require 'support/factory_bot'

as well as remove any fixture unused reference like this one config.use_transactional_fixtures = true

That should be it!, finally run any spec file you want inside rspec default folders e.g.: spec/features/my_action_spec.rb

spec/models/my_model_spec.rb

spec/task/my_task_spec.rb

or run them all and check depending on your setup

rspec

rails rspec

bundle exec rspec

hope this helps someone with the whole RSPEC + FactoryBot Gem installation process

Doh. Silly mistake here, running bundle exec rake spec instead of rake spec solved it.

Also had to add require 'factory_bot' to the top of support/factory_bot.rb
