What is a V-Model?

V-model is the most important model that is used in the process of software testing. It is also known as the verification and Validation Model. The late Paul Rook introduced it in the 1980s. The V-model is a sequential process in which the next phase begins only after the completion of the present phase. In this model, steps don’t move in a linear way while the steps are bent upwards.

 It is similar to the Waterfall model because we follow the V-model from left to right as well as follow a sequential path of execution of processes like in the waterfall model. In the waterfall model steps are followed as requirements, design, implementation, verification, and finally maintenance. In the same way, the same steps are followed in V-model. So we can say that V-model is the alternative to the waterfall model. 

In the software business, the Waterfall model and the V-Model are both highly popular development approaches. Both of these paradigms provide systematic assistance for the creation of apps. The primary distinction between the V-Model and the Waterfall Model is that the V-Model identifies flaws during the testing phase, whereas the Waterfall Model identifies flaws at the outset.

Let’s Learn more about the V-Model and the Waterfall Model in this post, as well as how they differ from one another.
