To become a testing expert, you should understand the difference between validation and verification if you want to work as a professional in the industry. The difference between validation and verification will be explained here

Aspect	Verification	Validation
Definition	Verification evaluates whether the software meets specified requirements and standards without executing the code.	Validation assesses whether the final software product meets user needs and expectations through actual Automation testing.
Focus	It focuses on checking documents design specifications code to ensure compliance with requirements.	It focuses on testing the final product to ensure that it is standard to meet the customer's needs and studies them.
Type of Testing	Verification is considered static testing, as it does not involve executing the code.	Validation is dynamic testing, as it requires executing the software to evaluate its functionality and performance.
Timing in SDLC	Verification occurs early in the software development lifecycle before coding begins. It ensures all specifications are met beforehand.	Validation takes place after development, ensure. This makes sure that the completed product meets user expectations and performs as intended
Error Handling	The primary goal is to prevent errors by identifying discrepancies early in the development process.	The focus is on detecting errors by evaluating if the product works correctly in real-world scenarios after development.
Methods Used	Common methods include reviews, inspections, static analysis, and walkthroughs. This is to verify documentation and design.	Functional testing is followed by usability testing, system testing, and user acceptance testing (UAT). This is to assess actual product performance
Outcome Focus	The outcome of verification is to ensure that the product is built correctly according to specifications.	The outcome of validation is to confirm that the right product has been built to meet user needs effectively.
Nature of process	Verification is a more objective process based on predefined criteria and standards, involving less subjectivity.	Validation is often subjective, relying on user feedback and real-world performance assessment to determine satisfaction with the product
Documentation Requirement	Verification requires comprehensive documentation such as design specifications and requirement documents for review and analysis.	Validation relies more on user interaction with the product rather than extensive documentation; it focuses on actual use cases and scenarios
Tool Used	Verification uses tools such as Checklists Static analysis tools Peer review processes Teams use these tools in order to ensure adherence to requirements without executing code.	Validation uses tools such as Automated testing frameworks Performance testing tools User feedback mechanisms These tools will help you evaluate the product's usability and functionality.
Goal Orientation	The goal is a really effective one. Verification's goal is to ensure quality by sticking to specifications during the development stages.	Validation focuses more on the satisfaction of the user. It actually verifies if the final product is up to the mark so that the customers will be happy with the product.
Examples	You should learn that reviewing design documents is a perfect example of verification. Also, performing code inspections before coding begins will be another example of verification.	Also, as you have seen the examples of verification, it is time to check out validation examples as well. The best example of validation is confirming if the software application is working properly so that there will be no flaws when people use it.
