What is the most prevalent way of using unit testing in Ruby? Do I require ‘test/unit’ and add test methods to production scripts and then comment the testing portions out when not testing? Or, should I develop a ‘testing’ version of the scripts identical to the production versions? Thanks for any advice. I’ve got the concept down… just thinking about implementation and actively using tests. Brad ---

Then I have a ‘run\_tests.rb’ file that runs all the tests. Here’s the entirety of run\_tests.rb: ``` Dir["tests/*"].each { |f| require f } ``` Or, you could somehow use Rake to run the tests, like Rails does. Joe ---

Chapter 12 of the Pickaxe includes some “best practices” for unit testing Ruby with Test::Unit. ---

I have a patch which fixes the test functionality in Minero A.'s setup.rb, which lets you create a test/ directory and run: ruby setup.rb test and it will execute all the tests in the test/ directory. Please email privately if you want the patch (I’ve already submitted it and recieved no response).
