...though, I've been sensing a growing convergence between agile programming and the open-source movement. I've seen agile concepts and terminology being adopted rapidly and enthusiastically by my colleagues in open-source-land — especially ideas like refactoring, unit testing, and design from stories and personas. From the other side, key agile-movement figures like Kent Beck and Martin Fowler have expressed strong interest in open source both in published works and to me personally. Fowler has gone so far as to include open source on his list of agile-movement schools. I agree that we belong on that list. But I also agree with Fowler's description of of open source as a style, rather than a process. I think his reservations as to whether open source can be described as just another agile school are well-founded. There is something more complicated and interesting going on here. and I realized when I read Fowler's description of open source that at some point I was going to have to do some hard thinking and writing in an effort to sort it all out. While doing research for my book The Art of Unix Programming, I read one particular passage in Fowler's Refactoring that finally brought it all home. He writes: One argument is that refactoring can be an alternative to up-front design. In this scenario, you don't do any design at all. You just code the first approach that comes into your head, get it working, and then refactor it into shape. Actually, this approach can...

...Business (Domain) Objects GUI Refactoring Core Java Values Simplicity Use the simplest design for the current functionality; don't try to anticipate tomorrow's needs. Code should be easy for a new developer to understand (or yourself a year later). Don't optimize for performance unless there's empirical evidence that it is needed. Be wary of building or using frameworks that make the application harder to understand. If you do need a framework (e.g. Spring for dependency injection), make sure the application's business logic isn't tied to the framework in any way. Maintainability Good naming is crucial. You should be able to read the code aloud, and a person listening to you should be able to understand what the code you are reading does Put responsibilities in the right place. Enforce a clean separation of the application's layers. For example, the UI code should not know anything about the database structure. Use well-known patterns and common idioms for the language. Maintain consistency at the module, application, and team level. There's always more than one way to do something, but doing it consistently is more important than finding the absolute best way. Information Classification: Limited Access Refactor your application code aggressively to maintain design quality in the face of changing requirements. Testing Use automated unit and regression tests to verify business functionality, minimize defects and enable safe refactoring Communication Developers, QA testers...

...developed and used in the software industry to detect anti-pattern. Towards the end, this paper also highlights some of the problems that are still open, to drive future research direction in this field. 1. Introduction Now-a-days, most of the software projects deal with large number of components that make the software more complicated and hard for novice designers to design. A design pattern is one of the most simple and powerful techniques used to improve the software design. Unfortunately, due to a number of market/customers constraints, anti-patterns may get introduced into the software systems and deteriorate its software quality. Hence, anti-patterns need to be carefully detected and monitored and, consequently, refactoring operations should be planned and performed to deal with them. In this paper, we will focus to present the different types of anti-patterns in object-oriented design, their symptoms and consequences, and the challenges and issues...

...during object design. There are two types of responsibilities, the “doing” and the “knowing.” The “doing” is known for doing something itself; it initiates the action in other objects and controls/coordinates the activities in other objects. The “knowing” is more about the related objects, private encapsulated data and things it can derive/calculate. Responsibilities related to “knowing” often are inferable from the Domain Model because of the attributes and associations it illustrates. That being said, a responsibility is not the same thing as a method, even though methods are applied to satisfy responsibilities. Methods are branded to either act alone or join forces with other methods and objects. Ensuing in the slides, we find refactoring. Refactoring is a well-ordered technique for restructuring an existing body of code,...

Efficient product delivery is achieved by using short iterations. But assuring the quality in any system is essential and imperative part which is very difficult task, which raises a question that: Is quality is assured in the software which is developed using agile methodology? The research paper proposed a solution and summarizes that how the quality is achieved or assure in agile software development using different factors. The major focus of this research paper is to analyse the quality parameter which assure quality in the agile methodology. The research paper includes the brief overview of the parameters which assure quality in agile. ———————————————————— I. INTRODUCTION. For the successful software engineering, the delivery of high quality software is needed. Mainly the customer satisfaction level is considered as the quality attribute which defines high quality of any system.

...Abstract: Agile methods in recent years have emerged as a new paradigm in software development, which promises to address some of the problem areas of traditional approaches by freeing some of its constraints. In an attempt to produce an improvised process to designing and implementation and thereby to produce qualitative deliverables, several pioneering efforts have been suggested. This paper examines two such methodologies that promote agility: eXtreme Programming and SCRUM. The process, the values and principles of the XP and SCRUM are described in detail. Crucial feature differences between XP and SCRUM and the advantages and disadvantages of both methodologies are also discussed. Keywords— XP, SCRUM, Agile INTRODUCTION The software development industry has been evolved to become the most important industries of time. This industry employs many practitioners world wide to create the most essential products that is been used to extend our lifestyles. From controlling the production of food we eat to providing safety and control of the vehicles, software has become the embodiment of the world's most valuable intellectual property.[15] In last few years, the trend to more agile has been the most significant event we have seen since the application of traditional software development process. The agile software methods and development is practices based approach which is empowered with values, principles and practices which make the I. software development process more easy...

...SAS Unit Testing Date Instructor SAS Unit Testing SAS Unit testing is one of the most popular methods for software testing. It is integrated automated process by which standalone units of any source code are tested by control data, usage procedures, and operating procedures. The whole process is done in order to determine whether software is good enough for usage. Unit tests are created by programmers or occasionally by white box testers during the development process. The process of unit testing is simple and hassle free as compared to any other form of software testing. Each test comprised in total testing procedure is different and independent from another. There could be various substitutes like method stubs, mock objects, fakes and test harnesses which could be implemented for proper independent checking of software independently. Software developers and designers write unit codes which act as building blocks of any program. These test runs are directed for achieving pre determined objectives of any program. While a developer writes any unit code for software development, he takes account of various permutations and combinations and accordingly writes the source. But actual implementation is possible only when that code is tested in working environment. There could be inherent errors in the software development which are caught only during this phase of unit testing. Implementation phase of unit testing is the most crucial phase as various processes...

...Muhammad 1 Mikey Muhammad Date Class Mr.Radev Java Programming and Inheritance As time continues to pass, the world we now live in is dominated by the use of technology. Technology continues to advance, and it seems, as if we can’t function without it. Whether it’s the use of technology in school or work, it is everywhere and you cannot escape it. It is important for us to be able to adapt to it and learn how the new inventions work and function properly. The Internet for example is one of the most important aspects of life today. The Internet allows us to have access to everything, and have endless information at our fingertips, whether it’s through a computer screen or through the use of a cellular device, or even a watch. Some of us choose to only use this amazing tool that has been provided to us, and then some us choose to go more in depth with this tool we call the Internet and want to know how it works. Although it takes millions of programs and concepts and other factors to get the Internet working how it does, the focus of my term paper will be Inheritance in Java. In order to truly understand what the specifics of Java are, you have to start with the totality of the Java program. The Java language could easily be the most difficult to understand because there are so many components to how it works. Java is a programing language and computing platform, which is a huge part of making the Internet work. It was first released by Sun Microsystems in 1995. Without...

...generates new requirements as a consequence of changes to the business, business goals, and business policies. Unless the system is adapted to reflect these requirements, its facilities will become out-of-step with the facilities needed to support the business and, hence, it will become less useful. Examples of process activities that support change are: 1. Recording of requirements rationale so that the reason why a requirement is included is known. This helps with future change. 2. Requirements traceability that shows dependencies between requirements and between the requirements and the design/code of the system. 3. Design modeling where the design model documents the structure of the software. 4. Code refactoring that improves code quality and so makes it more amenable to change ...
