Spork doesn't speed up my tests

Question

I use RSpec for my Rails 3 tests and try to use Spork.

I followed several tutorials and Spork seems to work without errors, but my tests still take the same amount of time to run (43 seconds) when turning Spork on and off.

How can I understand what is going on?

Gemfile

gem 'spork', '>=0.9.0.rc9' 

spec_helper.rb

 require 'rubygems' require 'spork' require 'factory_girl' require 'cover_me' Spork.prefork do # Loading more in this block will cause your tests to run faster. However, # if you change any configuration or code from libraries loaded here, you'll # need to restart spork for it take effect. # This file is copied to spec/ when you run 'rails generate rspec:install' ENV["RAILS_ENV"] ||= 'test' require File.expand_path("../../config/environment", __FILE__) require 'rspec/rails' # Force find of factory girl definitions. Tests started failing without this, and the factories could not be found Factory.find_definitions # Requires supporting ruby files with custom matchers and macros, etc, # in spec/support/ and its subdirectories. Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f} RSpec.configure do |config| # == Mock Framework # # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line: # # config.mock_with :mocha # config.mock_with :flexmock # config.mock_with :rr config.mock_with :rspec # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures config.fixture_path = "#{::Rails.root}/spec/fixtures" # If you're not using ActiveRecord, or you'd prefer not to run each of your # examples within a transaction, remove the following line or assign false # instead of true. config.use_transactional_fixtures = true # Needed for Spork ActiveSupport::Dependencies.clear end end Spork.each_run do # This code will be run each time you run your specs. end 

When I run → spork to start the server, everything looks fine:

→ spork Using RSpec Preloading the Rails Environment Loading Spork.prefork block ... Spork is ready and listens to 8989!

I also have --drb in the .rspec file

It depends on how you measure the runtime. If you include the time required to turn the rails, which should be faster, but the actual test execution time will not change.

Spork caches a rail environment that speeds up turnaround time but doesn't speed up actual run time.
