Software Testing Life Cycle Models

Software Testing Life Cycle Models

The various activities which are undertaken when developing software are commonly Modeled as a software development lifecycle. The software development lifecycle begins with the identification of a requirement for software and ends with the formal verification of the developed software against that requirement. The software development lifecycle does not exist by itself; it is in fact part of an overall Product lifecycle. Within the product lifecycle, software will undergo maintenance to correct errors and to comply with changes to requirements. The simplest overall form is Where the product is just software, but it can become much more complicated, with Multiple software developments each forming part of an overall system to comprise a Product. There are a number of different models for software development lifecycles. One thing Which all models have in common, is that at some point in the lifecycle, software has to be tested. This paper outlines some of the more commonly used software development Lifecycles, with particular emphasis on the testing activities in each model. A software life cycle model depicts the significant phases or activities of a software project from conception until the product is retired. It specifies the relationship between project phases, including transition criteria, feedback mechanisms, milestones, baselines, reviews, and deliverables. Typically, a life cycle model addresses the following phases of a software project: requirement phase, design phase, implemenentation, integration, testing, operations and maintenance. Much of the motivation behind utilizing a life cycle model is to provide structure. Life cycle models describe the inter relationship between software development phases .the common life cycle models are;
