Factory with carrierwave upload field [duplicate]

Answer 1

If you don't want to include ActionDispatch::TestProcess you can add files like this,

Factory.define :brand do |f|
  f.name "My Brand"
  f.description "Foo"
  f.logo { Rack::Test::UploadedFile.new(File.join(Rails.root, 'spec', 'support', 'brands', 'logos', 'logo_image.jpg')) }
end

Then just include the file at that given path, in this case it would be spec/support/brands/logos/logo_image.jpg

This is how they suggest doing it on their wiki https://github.com/jnicklas/carrierwave/wiki/How-to%3A-Use-test-fixtures

Answer 2

You need to include ActionDispatch::TestProcess in your factory (Rails 3), and use the fixture_file_upload helper:

include ActionDispatch::TestProcess

FactoryGirl.define do
  factory :image do
    title "Example image"
    file { fixture_file_upload("files/example.jpg", "image/jpeg") }
  end
end

Also be sure to create an example file at test/fixtures/files/example.jpg, otherwise you will get an error that the file does not exist.
