Description

Description

I tried to get all factories from spree gem, but overriding some of the factories, in this case user factories.
I add it them using require 'spree/testing_support/factories' in spec_helper.rb.

But

Using FactoryBot.modify I get

  Factory not registered: "user"

Using FactoryBot.define I get

  Factory already registered: user

Research direction

Start with the linked reproduction repository and the require in spec_helper.rb, then inspect how spree/testing_support/factories registers the user factories before FactoryBot.modify runs. Compare the KeyError from FactoryBot.modify with the duplicate-definition error from FactoryBot.define. Done means the gem-provided user factory can be overridden without either error, with the behavior demonstrated in the reproduction.
