Automated testing is an extremely important part of any software system. LeanDog's Cheezy will be showing us Cucumber, one of the most effective tools for full-stack acceptance testing. Unlike other acceptance testing systems, Cucumber allows business analysts or other stakeholders to write acceptance tests in a simple, accepted format. Developers can then take these tests and make them an executable part of their testing stack. This talk will give some background on acceptance testing and go into using Cucumber in your Ruby on Rails applications. Please note the change in time for this meeting. We'll be starting around 6:00 instead of the usual 7:00.
