FactoryBot to build list of objects with trait

Question

I'm using factory_bot to create objects in my test, here is a example of my factory:

factory :user do   name "John"   surname "Doe"    trait :with_photo do     ignore do       photo_count 1     end      after(:create) do |user, evaluator|       FactoryBot.create_list(:photo, evaluator.photo_count)     end   end end 

So I can create a user with photo like:

FactoryBot.create(:user, :with_photo) 

Or without photo :

FactoryBot.create(:user)  

Or create a list of users :

FactoryBot.build_list(:user, 5) 

But how can I build a list of users with trait (trait being :with_photo), if I wanted to create five of them with photo?

Note: FactoryBot was previously called FactoryGirl

Answer 1

Doesn't this work? It should...

FactoryBot.build_list(:user, 5, :with_photo)

Answer 2

You can also pass multiple traits to create_list and build_list example;

factory :user do   name { "Friendly User" }    trait :male do     name { "John Doe" }     gender { "Male" }   end    trait :admin do     admin { true }   end end  # creates 3 admin users with gender "Male" and name "Jon Snow" using the admin and male trait build_list(:user, 3, :admin, :male, name: "Jon Snow") create_list(:user, 3, :admin, :male, name: "Jon Snow") 

Just make sure the traits comes after the number of records you wish to create, the last argument is a hash that would override the record attribute.
