Install gem and plugin

sudo gem install parallel
script/plugin install git://github.com/grosser/parallel_tests.git

Adapt `config/database.yml`

test:
  database: xxx_test<%= ENV['TEST_ENV_NUMBER'] %>

Create test databases

script/dbconsole -p
CREATE DATABASE `xxx_test2`;
...

Generate RSpec files

script/generate rspec

(you'll probably only let it overwrite files in script/)

Prepare test databases

Now and after each migration:

rake parallel:prepare

Run tests

specs: rake parallel:spec
features: rake parallel:features

Multiple processes

If you want to test with multiple processes, you need to specify this when preparing the database and running the test, e.g:

rake parallel:prepare[4]
rake parallel:spec[4]

More than twice the amount of courses is probably not sensible, booting up rails takes its time, too.
