Agile Testing Is A Product Testing Practice Essay

Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders [1].

Agile methodology is a software development lifecycle which designed to produce faster development and high quality results compared with the traditional lifecycle. The Agile method focuses on incremental and iterative development where requirements, specifications, design, implementation, and testing continue throughout the project lifecycle (Nanthaamornphong, Morris, Rouson & Michelsen, 2013). Agile software development methods enable software developer to be more flexible and responsive to the changing environments and customer demands. However, Agile adoption comes with special challenges and fundamental organizational changes are necessary for successful outcome.

In the late 1990’s, there are several methodologies which attract public attention.These methodologies underlined importance of collaboration between the development team and business stakeholders; frequent delivery of business value, tight, self-organizing teams; and smart ways to craft, confirm, and deliver code. The term "Agile" was applied to this collection of methodologies in early 2001 when 17 software development practitioners gathered in Snowbird, Utah to discuss their shared ideas and various approaches to software development. This joint collection of values and principles was expressed in the manifesto of agile and the corresponding twelve principle.Software testing is the one most important attribute for software

Agile methodology is a set of tools and principles which shape up a certain approach to software development. It relies upon flexibility, iterative development, interaction between stakeholders, and adaptability to the changing environment and customer’s needs. Agile methodology was put forward in 2001 in Agile Manifesto when a group of the leading software developers gathered up to build up a common understanding of new approaches suitable for the modern times. Then, in 2001, four main Agile methodology principles were voiced which laid the foundation to the whole Agile methodology. Agile patrons agreed upon the following:

Agile testing is a software testing practice that follows the principles of the agile manifesto, emphasizing testing from the perspective of customers who will utilize the system. Agile testing does not emphasize rigidly defined testing procedures, but rather focuses on testing iteratively against newly developed code until quality is achieved from an end customer's perspective. In other words, the emphasis is shifted from "testers as quality police" to something more like "entire project team working toward demonstrable quality."

Agile Methodology is a new software development process at the end of the 20th century, to large extent it’s adaptive meets the

The Waterfall or Traditional model is a linear or Sequential approach to develop a Product. In this methodology, each phase of the product’s life cycle takes place in sequence of events like : Requirement gathering ,Design ,Developing ,System Testing ,User Acceptance Testing(UAT),Fixing the issues and delivering the finished product whereas Agile is an iterative and team based approach to develop a product. In agile methodology, Instead of developing the product with all the features at once we divide the project into the smaller segments called sprints and incorporate new features in each iterations or sprints. Instead of extensive planning and design up front, agile methodologies allow changing requirements over time by using the cross functional teams who work on successive iterations to develop a product. In this model, the goal of each iterative

Software development is one of the highest demands in all over the world. We use software development techniques to solve the problems and to satisfy customers. Agile software development is a conceptual framework for software; it is also a group of software development methods based on iterative development. In 2001, agile software development was created by seventeen people with a desire to find alternative approaches to software development. The most important thing about agile methods are team work, conveying information to the team, face to face conversation, and satisfy the customer. There are various methodologies but I am going to describe the most popular ones.

In the world of software development, the term agile typically refers to any approach to project management that strives to unite teams around the principles of collaboration, flexibility, simplicity, transparency, and responsiveness to feedback throughout the entire process of developing a new program or product. And agile testing generally means the practice of testing software for bugs or performance issues within the context of an agile workflow.

Agile software development refers to a group of software development methodologies e.g. Dynamics System Development Model, Crystal Methods and Extreme programming (XP methodology). Agile methods attempt to minimise the risk in software in short time boxes called iterations. Every iteration includes all the tasks necessary to release the mini increment of new functionality: planning, requirements analysis, design coding, testing and documentation. At the end of every iteration the priorities will be evaluated. Agile methods emphasise real time communication, preferably face to face instead of written documents. Agile methods also emphasise working software as the primary measure of progress. Agile methods produce very little documentation compared to other methods. Most Agile teams are located in a bullpen and include all the people necessary to finish the software. (1) (3)

Agile Methodology is an incremental, repetitious means of managing projects, particularly in the field of software development. These iterations, or sprints, give project managers many opportunities to evaluate and change the project during its lifecycle as well as keeping the end user informed and involved in development.

In agile development model, the development of software is in incremental, rapid cycles. It is building new features on previous functionality with each small incremental release. The software quality is maintained by rigorously testing each release. It is useful for time critical applications. The most well-known current agile development life cycle model is Extreme Programming (XP).

Yet unlike the methods that originated it, agile development is less confined and allows developers and teams to circumvent the red tape that more bureaucratic methods put forth. This newfound flexibility and freeform environment in agile development is feasible by excluding some of the extensive planning, detailed documentation, and defined cycles that are intrinsic to other traditional methods. This sort of approach deviates significantly from most traditional software engineering methods for many reasons. For example, unlike the waterfall method, agile development merges the testing and building phase as concurrent processes, speeding up the overall process. In ideal conditions Agile software development allows for earlier accessibility of software, gradual and iterative progress, and higher feasibility of change. However ideal conditions are not always the case in the real world. Due to the intentional reduction of analysis and planning, agile development is most effective and efficient in smaller sized and highly skilled teams. If teams can’t be quick to adopt a project, and make rapid progress, the agile method is not very effective.

“Agile Software Development is an umbrella term for a set of methods and practices based on the values and principles expressed in the Agile Manifesto. Solutions evolve through collaboration between self-organizing, cross-functional teams utilizing the appropriate practices for their context” (Agile Alliance, 2015).

Testing is an activity that can be planned and conducted systematically. Testing begins at the module level and works towards the integration of entire computer based system. Nothing is complete without testing, as it is vital for success of the system.
