Introduction

Corey Haines gave his Fast Tests talk at the Golden Gate Ruby Conference 2011 (http://confreaks.net/videos/641-gogaruco2011-fast-rails-tests), here's my feedback on it.

So first up, I think it's very interesting to see another take on how to speed up Rails testing. There's been a focus on it for a couple of years now with various solutions coming for it. From running tests in parallel, to tweaking the filesystem for faster access. Corey Haines take on it is that we should isolate ourselves from the framework that Rails provides and do as much as possible in plain Ruby objects and modules. In his talk he shows how he has been able to massively improve the runtime of his tests by implementing this.

I think it is a logical next step to the current that has been in the community for a while where we have been debating how to improve the design of Rails applications.

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").

Understanding MiniTest::Expectations

Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):

# minitest/spec.rb

module MiniTest::Expectations

# Be sure to have rails and thin installed.
require "rubygems"

# We are not loading Active Record, nor the Assets Pipeline, etc.
# This could also be in your Gemfile.
