Describe V-model in testing?

Hi Gaurav,


V Model

The V model gets its name from the fact that the graphical representation of the different test process activities involved in this methodology resembles the letter 'V'. The basic steps involved in this methodology are more or less the same as those in the waterfall model. However, this model follows both a 'top-down' as well as a 'bottom-up' approach (you can visualize them forming the letter 'V'). The benefit of this methodology is that in this case, both the development and testing activities go hand-in-hand. For example, as the development team goes about its requirement analysis activities, the testing team simultaneously begins with its acceptance testing activities. By following this approach, time delays are minimized and optimum utilization of resources is assured.

In the V Model SDLC, both the Development activity and the testing activities start almost at the same time with the same information. The development team does design and development and test team does the Test planning, scripting and testing. It's a parallel process for both development and testing. This model steps are quite similar to waterfall model. This is the one of the most popular model of software test life cycle.



Thanks
