The v-model in software testing refers to the verification and validation model, comprising phases such as requirements, high level design, low level design, implementation, and coding. It is particularly advantageous for small projects due to early defect detection, although changes mid-way necessitate revisions of test documents and specifications. Overall, it promotes proactive defect tracking but can be challenged by changes in requirements.

1. V-Model in Software Testing
V-model in software testing means
Verification and Validation model.

2. V-model phases
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

3. V-model phases
2) High Level Design Phase (HLD)
The high level design (HLD) stage
concentrates on system design and
architecture.

4. 3) Low Level Design (LLD)
The low-level design (LLD) stage is the
place where the software components are
designed.

5. V-model phases
4) Implementation Phase
The implementation stage is, once more,
where all coding happens.

6. V-model phases
5) Coding Phase
The modular level design is transformed
into code by the development guys.

7. Advantages of V-model
Ideal for small scaled projects where
understanding the requirements is an easy
task.
Defects can be detected at an very early
stage. Also known as the proactive defect
tracking.

8. Disadvantages of V-model
In the event that any progressions or
changes happen in halfway, then the test
documents alongside requirement
specifications, must be edited and changed.
