At Unruly teams have been applying eXtreme Programming (XP) since being founded in 2006. Teams take a test-first approach to developing code and invest in automated checks that can be run in live environments. InfoQ interviewed Rachel Davies about the importance of a continuous approach to testing, how this has evolved over the years and the business advantage that it delivers to Unruly.
Behavior driven development (BDD) can be used to improve communication between testers, developers and the business. For example you can use given-when-then scenarios to develop test scripts and at the same time define the requirements of the system. BDD involves all team members and helps them to think about the product.
