V-Model Testing (WEEK 12)

The meaning of V-Model is Verification and Validation model. This model has the shape of V, the V-shape model is a path of executions which is followed in a logical order. Each phase must be completed before the next phase begins.When we have test a product must be planned in parallel with the corresponding phase in V-Model. First is very important to understand the Verification and Validation techniques before we learn about V-Model. Verification testing technique is done without executing any code and Validation testing technique is done by executing the code, Verification is a static analysis technique, Validation is a dynamic analysis technique. Both techniques are par of the V-Model. There are 7 phases that take place in V-Model. Here I'm listing the seven phases of V-Model: Requirement Specification, Preliminary Design, Detailed Design, Coding, Unit Testing, Integration Testing and System Testing. We usually apply V-Model for small to medium sized projects where requirements are clearly defined and fixed. 

This design shows the sequential path of execution process of V-Model.

In this paragraph I'm covering the pros and cons of V-Model. Some of the pros are: Development and progress is very organized. This model works well for smaller and medium sized projects. Another positive factor is easy to manage as each phase of this model. Some of the cons of V-Model are : V-Model doesn't work for big and complex projects. The V-Model is not suitable if the requirements are not compatible.
