Spiral Model in Software Testing

This section will discuss various models for testing. Definitions of these models will differ. However, the fundamental principles are agreed on by experts and practitioners alike. There are many models used to describe the sequence of activities that make a Systems Development Life Cycle (SDLC). SLDC is used to describe activities of both development and maintenance work.

Developed by Barry Boehm in 1988. it provides the potential for rapid development of incremental versions of the software. In the spiral model, software is developed in a series of incremental releases. During early iterations , the incremental release might be a paper model or prototype.
Each iteration consists of
Planning, Risk Analysis, Engineering, Construction & Release & Customer Evaluation.
