Can't save carrierwave image in test environment

I am having some issues with Rspec 3 and carrierwave saving an image to a specified test directory. I have been reading the docs but am constantly faced with

Failure/Error: @uploader.store!(File.open("#{Rails.root}/spec/fixtures/yp2.jpg"))
NoMethodError:
undefined method `id' for nil:NilClass
# ./spec/rails_helper.rb:73:in `store_dir'

A tmp path is created at

/spec/uploads/tmp/

But the image is not saved at the following as expected

/spec/uploads/animal_image/image/12

in my rails_helper.rb I have

# set test specific store directory 
if defined?(CarrierWave)
 CarrierWave::Uploader::Base.descendants.each do |klass|
  next if klass.anonymous?
   klass.class_eval do
    def cache_dir
     "#{Rails.root}/spec/support/uploads/tmp"
    end 

    def store_dir
     "#{Rails.root}/spec/support/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    end 
   end 
  end 
end

and my actual test

require 'rails_helper'
require 'carrierwave/test/matchers'

describe AnimalImage do 
 include CarrierWave::Test::Matchers

before(:each) do
 AnimalImageUploader.enable_processing = true
 @uploader = AnimalImageUploader.new(@animal, :image)
 @uploader.store!(File.open("#{Rails.root}/spec/fixtures/yp2.jpg"))
end

after(:each) do
 @uploader.remove!
 AnimalImageUploader.enable_processing = false
end

context 'Image Versions' do

 it 'should scale large_animal_image to 555 x 365 ' do
  expect(@uploader.large_animal_image).to have_dimensions(555, 365)
 end
end 
end

Does anyone have any ideas as to why this could be happening?

Edit

Whilst doing some debugging I have captured the @uploader object from my spec

 <AnimalImageUploader:0x00000002dafa28 @model=nil, @mounted_as=:image

How do I set the model?

Edit 2

So after taking the comments on board provided by @rossta I have managed to get the images to save in the correct place along with all versions of the image but now I just need to find a matcher that will tell me that the versions of each image are the correct dimensions

before(:each) do
 AnimalImageUploader.enable_processing = true
 file = File.open("#{Rails.root}/spec/fixtures/yp2.jpg")
 @animal = AnimalImage.create!(image: file)
 @uploader = AnimalImageUploader.new(@animal, :image)
 @uploader.store!
end

In your test, @animal is the model, but you haven't set it's value to anything. Try creating an animal record or instantiating a stubbed version that respnds to methods like id:

before(:each) do
  AnimalImageUploader.enable_processing = true
  @animal = Animal.create!
  @uploader = AnimalImageUploader.new(@animal, :image)
  @uploader.store!(File.open("#{Rails.root}/spec/fixtures/yp2.jpg"))
end
