Overview

Provides RSpec-compatible & Test::Unit-compatible matchers for testing Paperclip attachments.

RSpec

In spec_helper.rb, you’ll need to require the matchers:

require "paperclip/matchers"

And include the module:

Spec::Runner.configure do |config|
  config.include Paperclip::Shoulda::Matchers
end

Example:

describe User do
  it { should have_attached_file(:avatar) }
  it { should validate_attachment_presence(:avatar) }
  it { should validate_attachment_content_type(:avatar).
                allowing('image/png', 'image/gif').
                rejecting('text/plain', 'text/xml') }
  it { should validate_attachment_size(:avatar).
                less_than(2.megabytes) }
end

TestUnit

In test_helper.rb, you’ll need to require the matchers as well:

require "paperclip/matchers"

And extend the module:

class ActiveSupport::TestCase
  extend Paperclip::Shoulda::Matchers

  #...other initializers...#
end

Example:

require 'test_helper'

class UserTest < ActiveSupport::TestCase
  should have_attached_file(:avatar)
  should validate_attachment_presence(:avatar)
  should validate_attachment_content_type(:avatar).
               allowing('image/png', 'image/gif').
               rejecting('text/plain', 'text/xml')
  should validate_attachment_size(:avatar).
               less_than(2.megabytes)
end
