V- Model Pros and Cons in Testing
he V - model is SDLC model where execution of processes happens in a sequential manner in V-shape. It is also known as Verification and Validation model. V - Model is an extension of the waterfall model and is based on association of a testing phase for each corresponding development stage. This means that for every single phase in the development cycle there is a directly associated testing phase. This is a highly disciplined model and next phase starts only after completion of the previous phase. V- Model design Under V-Model, the corresponding testing phase of the development phase is planned in parallel. So there are Verification phases on one side of the .V. and Validation phases on the other side. Coding phase joins the two sides of the V-Model. The below figure illustrates the different phases in V-Model of SDLC. Verification Phases Following are the Verification phases in V-Model: Business Requirement Analysis: This is the first phase in the development c...
