Test driven architecture – use your tests to inform architecture

As test-loving development teams, we are all painfully aware of the complexity of getting an application into the zen state of development – quick, test-driven red/green feedback for developers, software designs that are functionally on-the-money from a test-led, ÔÇťoutside-in” approach (from BDD), and a nigh on seamless continuous delivery process as a result. Very few teams achieve this, and those that do are frequently gifted a green-field project in which to engender them.

As test-savvy teams, when tests start to hamper the release process, we often assume our approach to testing needs an overhaul, but that might not be the case. Here we look at the role of architecture in test-driven applications, and examine whether we should listen to our tests to examine our macro design.
