V-Model in Software Testing

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

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

V-model phases

• 2) High Level Design Phase (HLD)
• The high level design (HLD) stage concentrates on
  system design and architecture.

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

V-model phases

• 4) Implementation Phase
• The implementation stage is, once more, where all
  coding happens.

V-model phases

• 5) Coding Phase
• The modular level design is transformed into code
  by the development guys.

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.

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.
