http://gsraj.tripod.com/design/creational/factory/factory.html http://blog.naver.com/erunc0?Redirect=Log&logNo=60029549507 The Problem One of the goals of object-oriented design is to delegate responsibility among different objects. This kine of partitioning is good since it encourages Encapsulation and Delegation. The Solution Factory Method is a creational pattern. This pattern helps to m..

http://www.irisa.fr/triskell/publis/2001/Baudry01b.pdf What are the testability improvements when using design patterns? Can the testability problems be localized (confined) to the diagram subset that corresponds to the application of a design pattern? Figure 4 - state machine implemented in a single class equivalent to a "functional" design Figure 5 - state machine implemented with the State d..

http://www.cs.colostate.edu/~rta/publications/ootestability.pdf#search=%22software%20testable%20design%20filetype%3Apdf%22 There are many reasons why object-oritened design and development has become the norm for software creation. Two primary resons are the positive impacts that abstraction/inheritance and information hiding have on the development process. As much as inheritance and informati..

EJB(Enterprise Java Beans)란 자바를 기반으로 분산형 엔터프라이즈(Enterprise)시스템에서 애플리케이션 개발시 필요한 컴포넌트로서의 빈즈(Beans)이다. (In Software Engineering, Java Beans are reusable software components : http://en.wikipedia.org/wiki/Beans) 이것은 통합된 환경에서 사용되는 비즈니스 객체를 위한 컴포넌트로서 자..

Abstraction We discuss preliminary experimental results shownig that automatic software partitinoing can significantly increase test coverage without generating too many false alarms caused by unrealistic inputs being injected at interfaces between units. 1. INTRODUCTION A new idea in this area is Directed Automated Random Testing(DART), which fully automateds software testing by combining thre..
