'''xUnit''' is a label used for an [[automated testing]] [[software framework]] that shares significant structure and functionality that is traceable to a common progenitor [[SUnit]].

The SUnit framework was [[Porting|ported]] to [[Java (programming language)|Java]] by [[Kent Beck]] and [[Erich Gamma]] as [[JUnit]] which gained wide popularity. Adaptations to other languages were also popular which led some to claim that the structured, [[Object-oriented programming|object-oriented]] style works well with popular languages including Java and [[C Sharp (programming language)|C#]]. 

The name of an adaptation is often a variation of "SUnit" with the "S" replaced with an abbreviation of the target language name. For example, JUnit for Java and RUnit for [[R (programming language)|R]]. The term "xUnit" refers to any such adaptation where "x" is a placeholder for the language-specific prefix.

The xUnit frameworks are often used for [[unit testing]] {{endash}} testing an isolated unit of code {{endash}} but can be used for any level of [[software testing]] including [[integration testing|integration]] and [[system testing|system]].
