1. V 型:
V模型是软件测试过程中最重要的模型。它也被称为验证和验证模型。它是由已故的 Paul Rook 在 1980 年代引入的。 V 模型是一个顺序过程,其中只有在当前阶段完成后才开始下一阶段。在此模型中,当台阶向上弯曲时,台阶不会以线性方式移动。

2. 螺旋模型:
螺旋模型是一种软件开发生命周期模型,高度用于风险驱动模型。基于给定项目的风险模式,螺旋模型帮助开发人员提高模型的效率,因为大多数风险已经处理。它由许多形成螺旋形状的循环组成,其中每个循环称为软件开发周期的阶段。

V型和螺旋型的区别:

S.No. V MODEL SPIRAL MODEL
1. V model is software development model but development and testing are not concurrent. Spiral model is a software development model and is made with features of incremental, waterfall or evolutionary prototyping models.
2. In V-model testing activities start with the first stage. Testing is done in spiral model at the end of the engineering phase.
3. Cost of V-model is expensive. While cost of spiral model is also very expensive.
4. Flexibility of V-model is Little flexible. Flexibility to change in spiral model is not that difficult.
5. Guarantee of success through V-model is high. Guarantee of success through Spiral model is low.
6. User involvement in V-model is also only in beginning. In this user Involvement is only at the beginning.
7. It is not iterative. It is iterative.
