Ruby Gem: Uninitialized constant FactoryBot

问题

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!!

回答1:

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

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
