attachment_fu testing in rails 3

Question

I am trying to write specs for a working file upload functionality using attachment_fu. However, the sample code given by the author for testing requires me to require

Answer 1

I was able to use fixture_file_upload just fine with Rails3 and rspec.

I just added include ActionDispatch::TestProcess to the spec_helper.rb, and then passed something like the following as the filedata:

fixture_file_upload(Rails.root.join("spec/support/test.png"), 'image/png')

EDIT: Something I upgraded changed the behavior of this to always include the fixtures path, so I switched to this instead of fixture_file_upload:

Rack::Test::UploadedFile.new(Rails.root.join("spec/support/test.png"), 'image/png')
