The big idea is “messaging” [...] The key in making great and growable systems is much more to design how its modules communicate rather than what their internal properties and behaviors should be. -- Alan Kay [Kay98] (src: Book_ Growing Object Oriented Software, Guided By Tests - Steve Freeman & Nat Pryce) (origin: [Kay98])
Roles, Responsibilities, Collaborators An object is an implementation of one or more roles; a role is a set of relatedresponsibilities; and a responsibility is an obligation to perform a task or know information. A collaboration is an interaction of objects or roles (or both).

start each feature with an acceptance test Domain Language only write the acceptance test using only terminology from the application’s domain, not from the underlying technologies (such as databases or web servers) benefits: prevent assumptions about implementation clarity focus on limited set of features user’s point of view (src: Book_ Growing Object Oriented Software, Guided By Tests - Steve Freeman & Nat Pryce) In Book_ Agile Technical Practices Distilled - Pedro, Marco, Alessandro they define test boundaries of acceptance test without external dependencies....
Quote: Walking skeleton definition A “walking skeleton” is an implementation of the thinnest possible slice of real functionality that we can automatically build, deploy, and test end-to-end. -- Alistair Cockburn (src: Book_ Growing Object Oriented Software, Guided By Tests - Steve Freeman & Nat Pryce) (origin: [Cockburn04]) keep the skeleton’s application functionality so simple that it’s obvious and uninteresting For example, for a database-backed web application, a skeleton would show a flat web page with fields from the database....
