Presentation: "Testing Your Presentation Layer"

Time: Wednesday 15:45 - 16:45

Location: Stanford

Abstract: In the Ruby world, no serious programmer would write an application without a comprehensive test suite. Unfortunately, the realities of integration testing the presentation layer of an Ajax-heavy web application has forced today's programmers to rely on kludges like HTML parsing in Ruby (which can't be used to test JavaScript comprehensively) or Selenium (which requires real-life browsers on every platform armed and ready). Screw that! With Johnson, a transparent Ruby to JavaScript bridge, you can test your JavaScript-heavy pages with ease. Because Johnson is embedded inside of Ruby, you'll be able to run tests directly in JavaScript, and then access JavaScript components in the tests (think Rails.dispatch_to("controller", "action")). I'll show you how to use Screw.Unit for browserless tests of your presentation layer. If you use continuous integration (and you should), you'll be able to easily catch bugs in your presentation layer without having to defer to a real browser running your tests.
