FactoryBot: create the same object multiple times

Question

In one of my RSpec test, I am creating multiple objects from the same factory definition

Eg

FactoryBot.create(:model_1)
FactoryBot.create(:model_1)
FactoryBot.create(:model_1)

Is there a method that factory_bot provides to do this in one line

I know that I can do

3.times {FactoryBot.create(:model_1)}

But I am looking for something that factory_bot provides for creating multiple objects of the same model.

You can create a list like this (hence create x objects at once):

FactoryBot.create_list(:model_1, 3)

Documentation lives here.

What if i want to create multiple objects like `FactoryGirl.create(:model_1, :type => "something")`? – usha Aug 26 '13 at 15:22

look in the doc, you can pass params hash as third argument – apneadiving Aug 26 '13 at 16:58

FactoryBot.create_list :factory_name, 2, attribute_name: 'value'

Simple and best way to move.

You can ignore the attribute names if not needed the same, and use sequence instead.

Not sure if this has been updated since the answer was posted, but now you would do the following

FactoryBot.create_list(:model_1, 3)

If you need to do this for a model with validation, I was able to do the following in my test.

10.times do |i|
  create(
    :object,
    property: i
  )
end
