ArgumentError: Factory not registered

Question

I am trying to get factory girl to run with rspec in my rails 4.1.1 app.

Problem is when I run rspec in my command line, i get Failure/Error: vers

Answer 1

There seems to be an issue when using rspec / factory girl with spring.

Adding:

config.before(:all) do
  FactoryGirl.reload
end

in my spec_helper.rb solved the issue.

Edit:

Another way to fix the issue is to manually tell Factory Girl where to load the factory. Add this in your spec_helper:

FactoryGirl.definition_file_paths = [File.expand_path('../factories', __FILE__)]
FactoryGirl.find_definitions

Answer 2

This is not necessarily caused by Spring. There is an issue that means factory_girl loads the paths slightly different from rspec. The solution is to to add to the rails_helper the following

FactoryGirl.definition_file_paths << File.join(File.dirname(__FILE__), 'factories')
FactoryGirl.find_definitions

assuming the helper is at engine_root/spec.

This occurs when you are using rspec in a rails engine.

This seems to be an issue with Factory Bot. I fixed it (as per the issue report) with FactoryBot.find_definitions:

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

  config.before do
    FactoryBot.find_definitions
  end
end
