Factory with carrierwave upload field [duplicate]

Answer 1

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.
