What are the key differences between verification and validation testing?

Verification ensures software is built correctly according to technical requirements using document reviews and static testing. Validation checks whether the software meets user needs through dynamic testing, such as functional and UAT.

When should I use verification vs. validation testing in my app development process?

Verification should be conducted throughout development, from requirement gathering to coding and integration. Validation occurs in the final stages, focusing on real-world testing to ensure the software meets user expectations.

What are the consequences of neglecting verification or validation testing?

Skipping Verification can lead to critical technical errors, increasing costs for future fixes. Without validation, the software may fail to meet user needs, resulting in poor user experience, loss of customers, and higher redevelopment costs.

How does verification improve the quality of the final software product?

Verification helps detect errors early, ensuring the software’s source code and design meet industry standards. This reduces defects during development, lowers repair costs, and produces a high-quality, stable product.
