How to override Factory Girl from Spree

I've been working with Factory Girl and Spree, and I'm going to share how I solved a problem I ran into by trying to override a factory from Spree, but first, I am going to tell a bit more from what I did.

My test was failing in this factory from Spree Core:

FactoryGirl.define do

  factory :credit_card, class: Spree::CreditCard do
    verification_value 123
    month 12
    year { Time.now.year }
    number '4111111111111111'
    name 'Spree Commerce'
  end

end

Did you see the problem? Ding ding ding! Yes, you are right fellow: the year is declared with Time.now.year; but what happens when you are already in that current month? My test was telling me something like:

Credit Card Expired

Here is where I need to do some workarounds to fix this issue. The first thing I tried is to override the FactoryGirl.define:

FactoryGirl.define do
  factory :credit_card, class: Spree::CreditCard do
    year { Time.now.year + 1 }
  end
end

Sadly, this triggered another issue about duplicated declaration, so I went to the FactoryGirl documentation and I found that they have a modify method which I tried to use as follows:

FactoryGirl.modify do
  factory :credit_card, class: Spree::CreditCard do
    year { Time.now.year + 1 }
  end
end

Still no luck. It was not recognizing credit_card as a declared method, so I was not sure at first what was going on. After taking a more detailed look, I made sure I was loading the Spree factories at the beginning of the file:

require 'spree/testing_support/factories'

FactoryGirl.modify do
  factory :credit_card, class: Spree::CreditCard do
    year { Time.now.year + 1 }
  end
end

And after this small change… everything went green!
This workaround helped me a lot, so I hope this can help you as well.

Thanks for reading! See you next time.
