1. V型:
V模型是在软件测试过程中使用的最重要的模型。也称为验证和验证模型。它由已故的保罗·鲁克(Paul Rook)在1980年代引入。 V模型是一个顺序过程,其中下一个阶段仅在当前阶段完成之后才开始。在此模型中,台阶在向上弯曲时不会线性移动。

2.增量模型:
增量模型是一种软件开发模型,其中对产品进行增量分析,设计,实施和测试,直到完成产品为止。发生了多个开发周期,并将这些周期划分为更多较小的模块。通常,在第一个模块期间会生产增量模型的工作软件。该模块的每个后续发行版都会在先前发行版中添加函数。在增量模型中,过程一直持续到完成整个系统为止。

V模型和增量模型之间的区别:

S.No. V MODEL INCREMENTAL MODEL
1. V model is software development model but development and testing are not concurrent. Incremental Model is a software development model where the product is, analyzed, designed, implemented and tested incrementally until the product is finished.
2. In V-model testing activities start with the first stage. Testing is done in incremental model after every iteration of phase.
3. Flexibility of V-model is Little flexible. Flexibility to change in incremental model is Easy.
4. Cost of V-model is expensive. Cost of incremental model is also Low.
5. Guarantee of success through V-model is high. Guarantee of success through Waterfall model is low.
6. In this user involvement is also only in beginning. In this user Involvement is only at the beginning.
7. It is not iterative. It is iterative.
