what is difference between verification(ver) and validation (val)?
Validation: Determination of the correctness of the products with respect to the user needs and requirements.
Verification: Determination of the correctness of the product with respect to the test conditions/requirement imposed at the start.
Its simply to understand i will give you a example below
Verification :User name, Password login page (your password is already stored to database when you entered password this value sent to database if its same one you will allow to login)
Validation : In Contact us form input field ( it described to basic structure,For example if you entered a mail id it check the basic id format if your input are fulfil the basic structure it take your value )
Verification
Verification is the process of evaluating products of a development phase to find out whether they meet the specified requirements.
The objective of Verification is to make sure that the product being develop is as per the requirements and design specifications.
Validation
Validation is the process of evaluating software at the end of the development process to determine whether software meets the customer expectations and requirements.
The objective of Validation is to make sure that the product actually meet up the user’s requirements, and check whether the specifications were correct in the first place.
See Below image for difference b/w verification & Validation.
Attachment 1954
You can easily understand.
Verification- Meeting the specific requirement
Validation- Whether the Functional requirement has been achieved

Verification and Validation both are used a find a defect in different ways. Verification is used to identify the errors in requirement specification.
Validation is used finds the defects in the implementation software application.
Consider anyone overall answer is one that validation is realated to client side and whereas Verification related to product side
As far as I have gained knowledge about verification and validation in website development I would say that there are some clear differences between verification and validation-
Verification
1. Verification uses methods like inspections, reviews, walkthroughs, and Desk-checking etc.
2. Verification is to check whether the software conforms to specifications.
3. It can catch errors that validation cannot catch. It is low level exercise.
4. Verification is done by QA team to ensure that the software is as per the specifications in the SRS document.
5. It generally comes first-done before validation.
Validation
1. Validation uses methods like black box (functional) testing, gray box testing, and white box (structural) testing etc.
2. Validation is to check whether software meets the customer expectations and requirements.
3. It can catch errors that verification cannot catch. It is High Level Exercise.
4. Validation is carried out with the involvement of testing team.
5. It generally follows after verification.
Good Luck.
Verification is the standing practice of verifying the documents, products, coding it could be anything, where we have to verify the things. It generally comes first before validation. Validation is the self-motivated mechanism of validating testing the actual products, it generally follows after verification.
Verification: Evaluates the intermediary products to check whether it meets the specific requirements of the particular phase.
Validation:Evaluates the final product to check whether it meets the business needs.
Verification:- Verification is the process of evaluating products of a development phase to find out whether they meet the specified requirements.
Validation:- Validation is the process of evaluating software at the end of the development process to determine whether software meets the customer expectations and requirements.
Verification is to make sure that requirements were built right and it does not involve Execution of code.
Validation is to make sure that requirements actually meet up users needs and it does not involve Execution of code.
