Testing with Lettuce and Splinter
by Adam Nelson
Lettuce, adapted from Ruby's Cucumber, is a behavior driven development (BDD) testing suite that sits on top of Splinter - a web driver for simulating real-world usage of your site. Learn the ins and outs of BDD using Lettuce and Splinter for rapid deployment.
Yipit uses Lettuce and Splinter to simulate users moving through the actual site under different scenarios. Unlike unit testing, this allows a tester to find problems at various levels (including Javascript and HTML defects) and under various situations specific to a browser environment. This talk will introduce various tools available right now as well as how to write extensible tests for a production environment. Ways to integrate testing into the release process will also be discussed.

Testing: The Developer Strikes Back
by Sandy Strong
“Code not tested is broken by design” - Jacob Kaplan-Moss Every programming project has unique testing needs. It’s not always easy to understand what those needs are, or how to write tests that satisfy them. One of our goals as developers is to write tests that minimize failures in production that can cost our companies time, money, resources, and in many cases, hours of sleep!
