Verification and Validation are two important phases in software testing. So As a software testers must be aware of the meaning and difference between the verification and validation .
Verification And Validation Definition
Verification : Verification is mostly depends on the software product’s requirements at the early stage of the project starts. It should be start analysis of the software product by requirements and design process. So Based on the analysis it can be confirmed the software products’ requirements.
Verification means Are we building the product right?
Validation : Validation is one the process where testers has to check the software product is as per the customer’s requirements or not. Testers are validating the software products is up to the mark or not. They are validating the actual product and expected product.
Validation means Are we building the right product?
In this article, we will discuss the verification and validation difference.
Difference Between Verification And Validation
|Verification considers as static testing.||Validation considers as dynamic testing.|
|Execution code process is not involved in verification.||Execution of code process is involved in validation.|
|The main purpose of verification is Are we building the product right?||The main purpose of validation is Are we building the right product?|
|In this phase, documents, designs and programs are analyzing.||In this phase, actual testing starts on the software product.|
|Verification can be helpful to finds the defects at the early stages of the process.||During detected defects in validation phase, it can not be identified in the verification phase.|
|Verification can be performed before validation.||Validation can be performed after Verification.|
|Quality Assurance Engineers team part of the verification process.||Software test engineers team is part of the validation process.|
|In Verification, Walkthrough, reviews and inspection activity performed.||In Validation, Functional testing, Non-functional testing, black box testing and white box testing performed.|
Verification And Validation Example
|Verification – Example||Validation – Example|
|Software product requirements – Login Module : |
1.Checks the Email Id field
2.Checks the Password field
3.Checks the Login button
4.Checks the design and layout of the Login page
5.Checks the Placeholders for the fields
6.Checks the spellings of the field title and placeholders
|Software Product Testing – |
Login Module :
1.Verify that user is able to login with valid email and password.
2.Verify that user is able to login with invalid email and password. 3.Verify that login button is working properly or not.
So, verification and validation in software testing both are important terms. We have tried to explain with an example. If you are looking for more differences then please visit below links.
