factory_bot-specific analysis for your projects, as an extension to RuboCop.

Just install the rubocop-factory_bot gem

gem install rubocop-factory_bot

or if you use bundler put this in your Gemfile

gem 'rubocop-factory_bot', require: false

You need to tell RuboCop to load the factory_bot extension. There are three ways to do this:

Put this into your .rubocop.yml.

plugins: rubocop-factory_bot

Alternatively, use the following array notation when specifying multiple extensions.

plugins:
  - rubocop-other-extension
  - rubocop-factory_bot

Now you can run rubocop and it will automatically load the RuboCop factory_bot cops together with the standard cops.

rubocop --plugin rubocop-factory_bot

RuboCop::RakeTask.new do |task|
  task.plugins << 'rubocop-factory_bot'
end

You can read more about RuboCop factory_bot in its official manual.

All cops are located under lib/rubocop/cop/factory_bot, and contain examples/documentation.

In your .rubocop.yml, you may treat the factory_bot cops just like any other cop. For example:

FactoryBot/AttributeDefinedStatically:
  Exclude:
    - spec/factories/my_factory.rb
