Getting started

First add your twitter username and password. Then server.rb and once it's started open websocket.html in your browser. You should see some tweets appear. If not take a look at the javascript console.

Testing front-end for a Sinatra app with RSpec and Capybara

I've used Cucumber quite a bit on my last job. It's an excellent tool, and I believe readable tests are the way to the future. But I could never get around to write effective scenarios, or maintain the boatload of text that the suite becomes once you get to a point where you have decent coverage. On top of that, it didn't seem to take much for the suite to become really slow as tests were added.

A while ago I've seen a gist by Lachie Cox where he shows how to use RSpec and Capybara to do front-end tests. That sounded perfect for me. I love RSpec, I can write my own matchers when I need them with little code, and it reads damn nicely.

So for my Rails Rumble 2010 project, as usual, I rolled a Sinatra app and figured I should give the idea a shot. Below are my findings.

To the members of the MIT community:

This past weekend, a distressing event disrupted the life of our campus community. I am writing now to share details about the incident and important information that affects us all.

The incident itself On Saturday, February 23 at 7:28 AM, the dispatch center at the Cambridge Police Department (CPD) received an electronic communication reporting an emergency at 77 Massachusetts Avenue. The communication came through a Sprint relay message service designed for people with hearing or speech impediments. The communication went on for more than 18 minutes, with a Sprint relay operator interacting with the caller and in turn communicating with a CPD dispatcher.

One minute into the communication, the caller reported someone with a “really big gun,” and “armor” who was “getting out of control.” The CPD dispatcher immediately sent CPD units and State Police to the site, and notified MIT Police.

Within two minutes of being notified, the first MIT Police units entered Buildi
