Explaining Verification and Validation in Software Testing - STLC Interview Question

One frequently asked STLC interview question is: "Can you explain the difference between verification and validation in software testing?"

Verification in software testing focuses on ensuring that the software meets the requirements and specifications set out at the beginning of the development process. It involves activities like reviews, walkthroughs, and inspections to check if the software is being built right.

Validation, on the other hand, is concerned with assessing whether the software meets the user's needs and expectations. It involves activities like testing the actual product with real-world scenarios to check if the software is doing the right thing.

Both verification and validation are crucial parts of the software testing process to ensure a high-quality product that meets the requirements and expectations of the end-users.
