Extreme programming (XP) is a software development methodology intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, [1] [2] [3] it advocates frequent releases in short development cycles, intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted.
You aren't gonna need it" [1] [2] (YAGNI) [3] is a principle which arose from extreme programming (XP) that states a programmer should not add functionality until deemed necessary. [4] Other forms of the phrase include "You aren't going to need it" (YAGTNI) [ 5 ] [ 6 ] and "You ain't gonna need it".
Extreme programming (XP) is an agile software development methodology used to implement software systems. This article details the practices used in this methodology. Extreme programming has 12 practices, grouped into four areas, derived from the best practices of software engineering. [1]
Kent Beck speaking in 2001. Kent Beck (born 1961) is an American software engineer and the creator of extreme programming, [1] a software development methodology that eschews rigid formal specification for a collaborative and iterative design process.
Unit testing is the cornerstone of extreme programming, which relies on an automated unit testing framework. This automated unit testing framework can be either third party, e.g., xUnit, or created within the development group. Extreme programming uses the creation of unit tests for test-driven development. The developer writes a unit test that ...
Class-responsibility-collaboration (CRC) cards are a brainstorming tool used in the design of object-oriented software. They were originally proposed by Ward Cunningham and Kent Beck as a teaching tool [1] but are also popular among expert designers [2] and recommended by extreme programming practitioners. [3]
Highly abstract or novel new concepts can be difficult to understand without concrete examples. [citation needed] Specification by example is intended to construct an accurate understanding, and significantly reduces feedback loops in software development, leading to less rework, higher product quality, faster turnaround time for software changes and better alignment of activities of various ...
Martin Fowler (18 December 1963) is a British software developer, [2] author and international public speaker on software development, specialising in object-oriented analysis and design, UML, patterns, and agile software development methodologies, including extreme programming. His 1999 book Refactoring popularised the practice of code ...
