Outside-In vs Inside Out - Comparing TDD Approaches

By Matt of Tea-Driven Development 10 days ago.
Email

…what we released to our user, they'd only be able to print receipts if they knew how to use an IRB prompt. That might seem ridiculous, but we've gone a long way to solving the problem, and we could probably spike a simple script that let them do it from the command-line without much risk.

Customizing IRB, 2010 edition

By Iain Hecker of Adventures with Ruby 1 month ago.

…terminal. While I'll save my terminal customizations for another time, I'll show you my IRB tweaks in this post.

There are several tools to improve your IRB, and some of them have been around for ages. But the arrival of Bundler makes it difficult to use them. Bundler creates a bubble in which you have to specify your dependencies explicitly.

For our first test consumer will use IRB, so open up a session and let's define 3 variables for: url of our provider, key and secret (use your own values) of our registered consumer: @ site={:site=>"http://localhost:3301"} @ mykey="SQnIXDQyhFB5q3wfZyMY" @ mysecret="PmW02FNs7rXG97sAVXMWhFoJVZ98cnj21vv6p1ad"

…demonstrated with this simple toy example. (Also, you can easily follow by copying and pasting the code to IRB and play with it.)

What do you do once you discover that you also have to apply the same formatting to a Set in a different location of your program? Right, you make it a function and write something like: def format_list(enum) puts "<ul>" enum.each do |x| puts " <li>#{x}</li>" end puts "</ul>" end

Chef 0.8.16 and Ohai 0.5.4 Release

We are also releasing Ohai 0.5.4. We were so busy getting our last release out the door that we didn't take time to announce all of the improvements in Ohai 0.5.2, so I'm going to talk about the improvements in both releases. The MVP for this …
