Don't like factory_girl because it is slow? Do you know that creating records in DB through factory_girl can take up to 50% of total spec run time? And even more!
This tiny gem helps fix that problem by reusing data preloaded before running test suite.
Without seeds:
Finished in 4 minutes 38.7 seconds
1402 examples, 0 failures, 0 pending
With seeds:
Finished in 2 minutes 40.6 seconds
1402 examples, 0 failures, 0 pending
>> (2.minutes + 40.6.seconds) / (4.minutes + 38.7.seconds)
=> 0.5762468604233943
So it is just about 58% of time before seeds optimization :)
Add this line to your application's Gemfile:
group :test do
gem 'factory_girl-seeds'
end
FactoryGirl::SeedGenerator.create(:user, name: "Carlos Castaneda")
For example if you are using rspec then add this to config.before(:suite)
.
This is the most important step because most of time factory_girl spends on creating associations which in turn also create associations and so on recursively.
FactoryGirl.define do
factory :post do
title "Demo"
user { seed(:user) }
end
end
Also if you need standard factory without overriding attributes then do not create records. Just use one from preloaded seeds.
it "should do something" do
user = FactoryGirl.seed(:user)
# your code here
end
Short DSL also available:
user = seed(:user)
FactoryGirl::SeedGenerator.create
method creates record in DB before transaction begins. Then it
block starts transaction so when you update record returned by FactoryGirl.seed
it is wrapped in transaction. This guarantees that every it
block works with clean record.
