fixturize your mongo(mapper) tests inline by caching blocks of created objects

fixturize

What problem does it solve?

Rails tests often create expensive objects in before(:each) / setup which gets shared between multiple tests.

Usually it's not inserting the raw data which takes a majority of the time; rather it's the instantiation and callbacks. So why not perform raw inserts instead?

Example

describe User do
  before :each do
    fixturize do
      @user = FactoryGirl.create(:user)
    end
  end

  it "should run this block faster the second time" do
    expect(@user.class).to eq(User)
  end
end

Install

Gemfile:

group :test do
  gem 'fixturize'
end

spec_helper.rb:

Fixturize.version = 1 # bump this if you change the source of a block
Fixturize.database = MongoMapper.database
Fixturize.enabled = true

# (only if you wipe your db between test runs):
RSpec.configure do |config|
  def wipe_db
    MongoMapper.database.collections.each do |c|
      unless (c.name =~ /system/ || Fixturize.collection_name == c.name)
        c.remove()
      end
    end
  end

  config.before(:each) do
    wipe_db
  end
end
