Software Testing And Quality Assurance Questions
Verification and validation are two important concepts in software testing and quality assurance.
Verification refers to the process of evaluating a system or component to determine whether it meets the specified requirements. It involves checking that the system has been designed and implemented correctly, and that it adheres to the specified standards and guidelines. Verification activities include reviews, inspections, and walkthroughs to identify defects and ensure that the system is built according to the design specifications.
On the other hand, validation is the process of evaluating a system or component during or at the end of the development process to determine whether it satisfies the specified requirements. It involves checking that the system meets the user's needs and expectations and performs its intended functions correctly. Validation activities include testing the system against the user requirements, conducting user acceptance testing, and ensuring that the system meets the desired quality standards.
In summary, verification focuses on checking whether the system is built correctly, while validation focuses on checking whether the system is built to meet the user's needs and expectations. Verification ensures that the system is error-free and adheres to the specified standards, while validation ensures that the system is fit for its intended purpose and satisfies the user's requirements.
