The V-Model is a sequential software development lifecycle model that illustrates a one-for-one relationship between major phases of development and corresponding test levels.
Key Characteristics:
- Clear mapping between development stages and testing phases
- Emphasis on early validation through corresponding tests at each phase
- Structured approach from requirements specification to delivery
- Focus on both verification (building the product right) and validation (building the right product)
- Encouragement of continuous feedback throughout the process
The V-Model promotes thorough documentation and planning, ensuring that quality assurance is integrated into every phase of development.
