How to Speed up image processing of Paperclip in Acceptance Tests

+1 vote

When running capybara feature specs I can see lots of Slow factory notices which are populated byfactory_girl. These Slow factory things heavy slow down the feature specs, I think, even feature specs are intrinsic slow specs. Then I had some inspect and found out most of the Slow factory was caused bypaperclip. We had model using paperclip here:

FactoryGirl.define do 
  factory :asset do 
    image Rails.root.join('spec/fixtures/sample.jpg').open 

So I wonder if there's a way like test mode for paperclip to speed up tests. I have simple solution here: Just copy the original file instead of actually crop it.

How many times do you test the same paths with this? Maybe judicious use of before(:all) for some tests might speed things up as well? Another though (not really knowing if this makes sense) — if your image is 1x1 pixels does it do anything? You really should not need to test the actual image rendering bits more than once or twice in your whole suite.

What is the best method to manage image uploads in Rails? Is there a tool that allows auto-resizing upon image upload based on predefined dimensions? Moreover, is there any tool available that makes it possible to render / regenerate the same originally uploaded image using alternative view based styles, e.g. thumbs, 320x200 or 640x480 etc..?

Which is the most efficient (i.e. processing speed) way to create a server application that accesses a database: A Servlet using JDBC; a JSP page using a JavaBean to carry out the db access; or JSP combined with a Servlet? Are these my only choices?
