Summary of Agile testing process Agile Testing

Since the earliest days of programming, when engineers manually set noughts and ones on huge electromechanical devices,pioneering practitioners have looked for ways of making the process of developing programs easier, quicker and more reliable. Once, software was used in just one or two places around the world by a handful of people to implement the complex algorithms needed to decode secret military messages. Now,the world runs on software; it is everywhere–in your home, in your car, in your mobile phone,sometimes even inside you (think about the complex calculations made by heart pacemaker devices or the new generation of intelligent digital hearing aids). Today, a world without software is absolutely unthinkable. As the technologies for developing software have evolved and increasing numbers of software practitioners have found employment4 in more and more companies, producing ever larger and more complex software systems, the need to find easier, quicker and more reliable practices for delivering that software has become absolutely critical.

In the early days, practitioners began to share the successful practices that they had found, often through trial and error, with their colleagues.As the IT industry matured, such best practices began to be documented and distributed, resulting in the appearance of papers and books on waterfall and spiral software development methods, for example. While of initial value in managing relatively simple software projects where customer requirements were unlikely to change across the duration of the project,many workers became increasingly dissatisfied with these early methods as continuous improvements in the capability of programming technologies encouraged developers to produce systems of ever-increasing size and complexity, and as the number of software disaster stories began to accumulate.

NOTE:- It is an incredibly sobering thought that in the 1940s there were just a few people in the entire world who could implement a computer program,but that today each year some 85,000 software engineers leave U.S.universities,with an additional 400,000 Indian graduates joining them,while China’s education system produces some 600,000 developers annually!Inevitably, these numbers can only increase year after year.

Increasingly,the need to be responsive to changing customer needs, to be able to quickly develop,test,and deliver useful functionality to the customer in a planned and managed incremental manner, the need to reduce the cost and effort of development, and the need to deliver high-quality software led practitioners to challenge the role of traditional approaches to software development and testing.

In the twenty-first century,software development needs to be agile;to deliver quality software that meets the customer requirements and that is delivered on time and within budget.Because, bottom line, if you can’t – your competitors will.
