In software development, the V-model represents a development process that may be considered an extension of the waterfall model, and is an example of the more general V-model. Instead of moving down in a linear way, the process steps are bent upwards after the coding phase, to form the typical V shape.

What is V-Model explain?
The V-model is an SDLC model where execution of processes happens in a sequential manner in a V-shape. It is also known as Verification and Validation model. The V-Model is an extension of the waterfall model and is based on the association of a testing phase for each corresponding development stage.
Why it is called as V-Model?
Verification and Validation phases are joined by coding phase in V-shape. Thus it is called V-Model.
Where is V-Model used?
It can be used for software projects of any size, whether in commerce, the military or the public sector. The model serves as a tool to facilitate the organization and execution of development, maintenance, and advancement of diverse IT systems.
What is V-Model in engineering?
The V-Model is an approach model that was developed by commissioning of the State of Germany for planning and implementing system development projects. It considers the entire lifecycle of a system nicely fitting the line of thinking in systems engineering.
What are advantages of V model?
Advantages of V-model:
Hence higher chance of success over the waterfall model. Proactive defect tracking – that is defects are found at early stage. Avoids the downward flow of the defects. Works well for small projects where requirements are easily understood.
Who invented V model?
A basic V-Model. In 1979, Barry W. Boehm published a paper [15] that was built up on the Vee. He used the Vee in the context of software engineering to emphasize the importance of verification and validation.
What are the phases of V-Model?
EXAMPLE To Understand the V Model
| Different phases of the Software Development Cycle | Activities performed in each stage |
|---|---|
| Test Stage | Next, you test the software to verify that it is built as per the specifications are given by the client. |
| Deployment stage | Deploy the application in the respective environment |
What is the difference between V-Model and agile?
Agile Model is the software development model in which development and testing process carries on simultaneously.
Difference between Agile Model and V-Model:
| Agile Model | V-Model |
|---|---|
| Testing is easy as compared to V-model. | Testing is hard as compared to Agile model. |
| It consists of total five phases. | It consists of five verification and five validation phases. |
What is difference between WaterFall and V-Model?
In V-Model the probability of total number of defects in the development of application is low as testing is done in parallel to the development. On other hand in WaterFall Model the probability of total number of defects in the development of application is high as testing is done post development.
What is fish model and V-Model?
In Fish model every stage is tested by other team for completeness and correctness. In V model every stage same person reviews but in last stage software testing will be done by other testers.
What is unit testing in V-Model?
Unit testing
In the V-Model, Unit Test Plans (UTPs) are developed during module design phase. These UTPs are executed to eliminate bugs at code level or unit level. A unit is the smallest entity which can independently exist, e.g. a program module.
Can you explain the V-Model in manual testing?
The V-Model is a model used to describe testing activities as part of the software development process. The V-Model can be interpreted as an extension of the Waterfall development model, which describes the testing activities as one of the last steps in a sequential development process.
What are the strength and weakness of V-Model?
A Comparison Table for Advantages And Disadvantages of V Model
| Advantages | Disadvantages |
|---|---|
| The V Model provides a proactive error tracking feature for developers. | The V Model software is developed during the phase of implementation, so no initial prototypes of the software are produced. |
What are different types of testing?
The different types of tests
- Unit tests. Unit tests are very low level and close to the source of an application.
- Integration tests.
- Functional tests.
- End-to-end tests.
- Acceptance testing.
- Performance testing.
- Smoke testing.
What are the pros and cons of V-Model?
Pros and Cons of using V model
| PROS | CONS |
|---|---|
| – Works well for smaller to medium sized projects. | – Not suitable if the requirements are not consistent. |
| – Testing starts from beginning so ambiguities are identified from the beginning. | – No working software is produced in the intermediate stage. |
What is the purpose of the V diagram?
The V-model is a graphical representation of a systems development lifecycle. It is used to produce rigorous development lifecycle models and project management models.
Is V-Model a methodology?
The evolution of the Waterfall methodology to incorporate more defined testing phases is depicted by the v-shaped infographic that explains the evolved approach. The V-model’s v also represents the extended ‘Verification and Validation model’ the methodology can also be referred to as.
What is difference between verification and validation?
Validation is the process of checking whether the specification captures the customer’s requirements, while verification is the process of checking that the software meets specifications.
What is sanity testing?
Definition: Sanity testing is a subset of regression testing. After receiving the software build, sanity testing is performed to ensure that the code changes introduced are working as expected . This testing is a checkpoint to determine if testing for the build can proceed or not.
Can you use V-Model in Agile?
Combining agile development with the V-model is not a contradiction. They can both work very well together, as shown in the figure following: Agile methods use story maps including epics, themes, features and user stories for logical decomposition. This maps well to the left side of the V.
