what is the significance of V model software testing cycle?

Answer 1

There are many.. below mentioned are a few of those.

V Model or Life cycle testing involves continuous testing of the system during the developmental process. At predetermined points, the results of the development process are inspected to determine the correctness of the implementation. These inspections identify defects at the earliest possible point.
when the project starts both the system development process and system test process begins. The team that is developing the system begins the systems development process and the team that is conducting the system test begins planning the system test process. Both teams start at the same point using the same information.

As a result of this simultaneous process involved in V-Model, the product quality is at its best.

In the basic Waterfall model process seen some disadvantages or limitations in the model which started a new SDLC model. As we seen in the Waterfall model the issues found in the end of the SDLC, this is due to the testing is occurred in the end phases of the you SDLC. To overcome this problem the V-Model is comes into the picture. It is always better to introduce testing in the early phase of SDLC, as in this model the testing activity gets started from the early phase of the SDLC.
In the V Model Software Development Life Cycle, based on same information(requirement specification document) the development & testing activity is started. Based on the requirement document developer team started working on the design & after completion on design start actual implementation and testing team starts working on test planning, test case writing, test scripting. Both activities are working parallel to each other. In Waterfall model & V-model they are quite similar to each other. As it is most popular Software Testing Life Cycle model so most of the organization is following this model.

The V-model is also called as Verification and Validation model. The testing activity is perform in the each phase of Software Testing Life Cycle phase. In the first half of the model Verification testing activity is integrated in each phase like review user requirements, System Design document & in the next half the Validations testing activity is come in picture.

Typical V-model shows Software Development activities on the Left hand side of model and the Right hand side of the model actual Testing Phases can be performed.

V-Model is a process in which Development & Testing Start almost at the same time with the same Information.
It's also known as Verification & Validation Model.
