I was performing functional tests on my models that employed Attachment_Fu this morning and thought it would be worthwhile to share the code since it was a bit of a hassle pulling it together. Kudos to Mike Subelsky for his introduction to functional testing Attachment_Fu. It got me going in the right direction. What proved difficult once again was the multi-model controller. Once I got over that hump, I was on my way. As you can see from all the detail in the HTTP POST below, that was not an entirely easy task.

class ProductsControllerTest < Test::Unit::TestCase 
def test_create_with_user     
num_products = Product.count     
imgdata = fixture_file_upload('/files/image.png', 'image/png')     
audiodata = fixture_file_upload('/files/sound.mp3', 'audio/mpeg')     
post :create, {:product => {
:name => "Widget",
:description => "A small tool-like item",
:weight => "3",
:price => "19.99",
:language_id => "1"
:image => {:uploaded_data => imgdata},
:audio => {:uploaded_data => audiodata} ,
:html => { :multipart => true }
{:user_id => users(:valid_active_user).id}
assert_response :redirect
assert_redirected_to :action => 'show'
assert_equal num_products + 1, Product.count
