Where does design fit in agile projects? What is refactoring and what isn’t refactoring? What is the relationship between design and refactoring, and design and architecture? In this talk we will clarify these and other questions around emergent design and how a TDD/BDD tool like PhpSpec can help you with the process. We will look into how PhpSpec helps uncover smelly code and point in the direction of refactoring techniques to guide the design of flexible, testable and easy to extend object oriented PHP code – enabling developers to focus on what’s more valuable for the customer at all times and re-steer the direction of the product.
