1.- Start Spork in a terminal window.
2.- Write a single test or small group of tests.
3.- Run Command-Shift-R to verify that the test or test group is red.
4.- Write the corresponding application code.
5.- Run Command-Shift-E to run the same test/group again, verifying that it’s green.
6.- Repeat steps 2–5 as necessary.
7.- When reaching a natural stopping point (such as before a commit), run rspec spec/ at the command line to confirm that the entire test suite is still green.

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade

=> true
[2] pry(main)> test_string = "/foo/bar/bah/bing"
=> "/foo/bar/bah/bing"
String#starts_with?

[3] pry(main)> Benchmark.realtime { (1..10000).to_a.each { %r{^/foo}.match(test_string) } }
=> 0.009987447

Setup new Mac with OSX Lion from scratch

These commands are good as of 2011-07-27.

Install Xcode 4

The download/install takes a while so start it first. When it finishes downloading you will still need to run it to complete installation.

iTerm2

Really the nicest choice for a terminal on OSX right now, especially with Lion style full screen support.
