Erich Gamma is a Swiss computer scientist and one of the four co-authors (referred to as "Gang of Four") of the software engineering textbook, Design Patterns: Elements of Reusable Object-Oriented Software.
Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book describing software design patterns.The book was written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, with a foreword by Grady Booch.
State in UML [1]. In the accompanying Unified Modeling Language (UML) class diagram, the Context class doesn't implement state-specific behavior directly. Instead, Context refers to the State interface for performing state-specific behavior (state.handle()), which makes Context independent of how state-specific behavior is implemented.
He wrote the SUnit unit testing framework for Smalltalk, which spawned the xUnit series of frameworks, notably JUnit for Java, which Beck wrote with Erich Gamma. Beck popularized CRC cards with Ward Cunningham, the inventor of the wiki. He lives in San Francisco, California and previously worked at Facebook. [2]
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 ported to Java by Kent Beck and Erich Gamma as JUnit which gained wide popularity.
A class diagram exemplifying the singleton pattern.. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
JUnit was born on a flight from Zurich to the 1997 OOPSLA in Atlanta. Kent was flying with Erich Gamma, and what else were two geeks to do on a long flight but program? The first version of JUnit was built there, pair programmed, and done test first (a pleasing form of meta-circular geekery).
The Bridge design pattern is one of the twenty-three well-known GoF design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.
