== Creating the test database

Unless you are using SQLite, you will have to create the database, matching
the parameters specified in test/database.yml

== Running the test

Set ENV['DB'] to something other than 'sqlite3' if you need to, otherwise you're good to go.

To run the unit test, just run the unit test. :)
ruby test/before_assignment_test.rb

If you see the following, then everything is good:
