Much the same as the waterfall model the V-Shaped life cycle is a consecutive path of execution of procedures. Every stage must be completed before the following stage starts. T esting of the product is arranged in parallel with a parallel stage of development in V-model. Now let us look at the basic structure of the V-model based on the various phases involved in it. 1. Requirements Phase: Prerequisites like BRS and SRS are the starting points of the life cycle be it software development life cycle or the testing life cycle. Simply like the waterfall model. In any case in this model before the development phase begins an application test plan is designed. The test plan aims at meeting the functionality indicated in the prerequisites or requirements document. 2. High Level Design Phase HLD: The high level design HLD stage concentrates on system design and architecture. It gives review of system product solution platform and process/service. A plan for integration test is prepared in this stage too with a specifc end goal to test the bits of the software systems’ capacity to work in tandem. 3. Low Level Design LLD: slide 2: The low-level design LLD stage is the place where the software components are designed. It characterizes the actual logic for every single segment of the system. Class diagram with every one of the methods and connection between classes goes under LLD. Component tests are made in this stage too. 4. Implementation Phase: The implementation stage is once more where all coding happens. When coding is fnished the way of execution proceeds up the right half of the V where the test plans created before are currently put to utilize. 5. Coding Phase: The bottom most point in the V-shaped model. The modular level design is transformed into code by the development guys. Ideal Situation to Use the V-model: High trust of client is required for picking the V-Shaped model methodology. Since no prototype models are created there is a high hazard required in meeting client desires. • The V-shaped model ought to be utilized for small scale to medium scale projects where necessities are plainly stated and fxed. • The V-Shaped model ought to be picked when abundant technical resources are accessible with required specialized skill. Advantages of Using the V-model: 1. Ideal for small scaled projects where understanding the requirements is an easy task. 2. Defects can be detected at an very early stage. Also known as the proactive defect tracking. 3. Refrains the downside fow of the defects in the product or the appliaction. slide 3: 4. T esting exercises like planning test outlining happens well before coding. This spares a great deal of time. Thus higher possibility of accomplishment over the waterfall model. 5. Very easy to use and easily understandable. Disadvantages of Using the V-model: 1. In the event that any progressions or changes happen in halfway then the test documents alongside requirement specifcations must be edited and changed. 2. Software is created amid the implementation stage so no early prototype models of the product are delivered. 3. Happens to be very rigid and lacking fexibility. This is a widely used model in the software testing industry. In this model the testing and the development phases progress in a parallel manner. T esting starts from a very early stage. Bugs can therefore be found at a very early stage and can be fxed there and then. Here it is not the case that frst the development phase is completed and then testing is started. A lot of time is thus saved in the V- model. The waterfall model progresses in a sequential manner. This article would be helpful for student Software Testing reviews. More Related Video: 1.
