Although the words verification and validation are frequently used in software engineering, they relate to two different forms of examination. Let us discuss some more differences between Verification Vs Validation with the help of the comparison given below.
What is verification?
Verification is the process of ensuring that software meets its objectives without errors. It is the process of determining whether or not the product generated is correct. It determines if the generated product meets our standard, static testing is what verification is.
What is validation?
validation is the process of determining if a software product is adequate, or whether it meets high-level criteria. it is the process of verifying validation, which ensures that the product we are building is correct. i is the verification of the real and intended product. Dynamic testing is called validation.
Verification Vs Validation | Difference | Comparison
- The verification process involves verifying documents, designs, codes, and programs, whereas the validation phase involves testing and validating the real product.
- Verification does not entail code execution but the validation does.
- Verification employs procedures such as reviews, walkthroughs, inspections, and desk checking. Whereas validation employs procedures such as black box testing, white box testing, and non-functional testing.
- Validation determines if the program satisfies the needs and expectations, whereas verification determines whether the software confirms a specification.
- When comparing verification versus validation testing, the verification process occurs first followed by the validation phase.
- Verification detects defects early in the development cycle, whereas validation defects bugs that verification misses.
- Validation determines if the program satisfies the needs and expectations, whereas verification determines whether the software confirms a specification.
- The QA team does verification whereas the testing team collaborates with the QA team to provide validation.
- In software testing, the verification process targets software architecture, design, databases, and so on. Whereas the validation process targets the actual software output.
- Verification is static testing. Validation is dynamic testing.
- The execution of the code is not included in verification. While validation also involves code execution.
- Verification comes before validation. Validation comes after verification.
