AGILE methodology is a practice that promotes continuous iteration of development and testing throughout the software development lifecycle of the project. Both development and testing activities are concurrent unlike the Waterfall model I hope we got an idea of Agile!!! Now, we can step on to Agile Testing. The agile software development emphasizes on four core values. Individual and team interactions over processes and tools Working software over comprehensive documentation Customer collaboration over contract negotiation Responding to change over following a plan Agile Vs Waterfall Method Agile and Waterfall model are two different methods for software development process.

One member of the team might have more focus and help drive or awaken the other if they lose focus, and that role might periodically change. One member might have knowledge of a topic or technique which the other does not, which might eliminate delays to find or test a solution, or allow for a better solution, thus effectively expanding the skillset, knowledge, and experience of a programmer as compared to working alone.

Each of these intangible benefits, and many more, may be hard to accurately measure, but can contribute to more efficient working hours. Design quality[ edit ] A system with two programmers possesses greater potential for the generation of more diverse solutions to problems for three reasons: the programmers bring different prior experiences to the task; they may access information relevant to the task in different ways; they stand in different relationships to the problem by virtue of their functional roles.

In an attempt to share goals and plans, the programmers must overtly negotiate a shared course of action when a conflict arises between them. In doing so, they consider a larger number of ways of solving the problem than a single programmer alone might do.

This significantly improves the design quality of the program as it reduces the chances of selecting a poor method. This helps pair programmers to learn to communicate more easily. The empirical studies tend to examine the level of productivity and the quality of the code, while meta-analyses may focus on biases introduced by the process of testing and publishing.

A meta-analysis found pairs typically consider more design alternatives than programmers working alone, arrive at simpler more maintainable designs, and catch design defects earlier. However, it raised concerns that its findings may have been influenced by "signs of publication bias among published studies on pair programming". It concluded that "pair programming is not uniformly beneficial or effective". The relative weight of these factors can vary by project and task.

TDD results in higher quality systems and provides comprehensive detailed system documentation. TDD is a recent discovery that comes out of the extreme programming XP world. Most developers with TDD experience are thrilled by the value it brings them.

A programmer learning with Agile Java understands how to translate oral requirements into tests, and tests into code. They also learn how TDD impacts the design of the system, and vice versa. In short, readers of Agile Java will understand what it takes to build a professional, robust software system using Java. Agile Java: — Presents a way of learning Java in conjunction with object-oriented design and test-driven development.

Jeff Langr is the author of the praised book Essential Java Style, as well as several articles on software development. Langr has extensive experience in Java and TDD.

The TDD approach provides a very high amount of immediate feedback to students, something I believe is very valuable in the learning process. Due in bookstores later this month. TDD is more than a nice idea. It is a proven methodology that can be used to simplify the development environment and help developers produce better software.

Of course some things that sound good in theory are hard to put to practice. TDD is not that hard to put into practice but it does take some new knowledge and experience to properly implement.

It also introduces the requirements for the Football Pool application that will be used throughout the rest of the book. As described in the beginning of this chapter, it is important to take the time to set up your development environment to make it easy to create software. Unit Testing: The Foundation of Test-Driven Development In this chapter, Hammell puts the theory of chapter 1 and the tools discussed in chapter 2 into practice. He starts out by developing a simple unit test that should help you write the code for a base class belonging to the Football Pool application.

Finally, this chapter shows how to develop around dependent classes.
