After spending the better part of a day getting this figured out - here's how to test for attachment uploads using Rspec and paperclip

In the model spec

@attr = { :name => "Example Name", 
              :description => "Example Description",
              :image => Rack::Test::UploadedFile.new('spec/fixtures/images/test.jpg', 'image/jpeg')
            }

In the controller spec

rake db:migrate

rake db:test:prepare

rails generate migration AddColumnToTable col_name:type

Requires ImageMagick

sudo apt-get install imagemagick libmagickcore-dev

add

gem "paperclip", "~> 2.4"

to your Gemfile then

bundle install

Done

Add

gem 'rack', '1.3.3'

to your Gemfile

then run:

bundle update

What should I test for when I'm doing test driven development?

Data (Model) Tests

• Validations
• Methods

Function (controllers)  Tests

• Request Success (e.g. 200 or 300 received)
• Got the correct page
• Authenticated correctly
• Proper objects as expected
• Proper message displayed

Integration Tests

• Test the interactions between functions/controllers

Test Routes

• For RoR check that the urls go to the correct place

Test Mailers
