Answer 1

Make sure your individual factory files are not ending with _spec.

Answer 2

Call FactoryGirl.define(:user) or FactoryGirl.find_definitions twice you also have this problem.

Try removing the second call or:

FactoryGirl.factories.clear
FactoryGirl.find_definitions  

Answer 3

The strangest thing, I got this error with the following syntax error in the code:

before_validation :generate_reference, :on: :create

:on: was causing this error. How or why will remain a mystery.

Answer 4

for me, this issue was coming because was using both gems

gem 'factory_bot_rails'
gem 'factory_girl_rails'

to solve I removed gem 'factory_bot_rails' from gem file. and also added require 'factory_girl' to spec/factories/track.rb file.

if Rails.env.test?
    require 'factory_girl'
    FactoryGirl.define do
      factory :track do
            id 1
            name "nurburgring"
            surface_type "snow"
            time_zone "CET"
       end
    end

I hope this will help.

Answer 5

Another possible reason is spare call of FactoryGirl.find_definitions. Try to remove find_definitions if found.

Answer 6

I had exactly the same problem. It occurs when you use the scaffold generator. It automatically creates a factory in test/factories/ So generally just deleting this file solve your issue
