Which testing method focuses on integrating verification tests across all stages of development?

Walkthrough
Static Test
V-model
Dynamic Testing

The correct answer is: V-model

The V-model is a development model that emphasizes the importance of validation and verification at each stage of the software development lifecycle. It represents a model where each phase of development (such as requirements analysis, design, implementation, and testing) corresponds to a related testing phase. This structured approach enables integration of verification tests throughout the entire process rather than waiting until the end of development to begin thorough testing. By promoting early testing, the V-model helps identify defects earlier in the process, which can save time and resources in the long run. Each development activity has a corresponding testing activity, so as the product evolves, verification is built into the process at each stage, ensuring that the product meets the specified requirements as it is being developed. This methodology supports a systematic approach to quality assurance, where both verification (to ensure the product is built correctly) and validation (to ensure the right product is built) are conducted in tandem, making it an effective means of achieving high-quality software.
