Today, we’ll be talking about verification and validation in software testing. According to the IEE-STD-610 (a set of software engineering standards), verification testing is “A test of a system that demonstrates that it meets all the particular requirements at a specific stage of its development.”
Verification testing is the technique used to examine all predetermined software specifications, documents, code, design, and programs to assure that the software fulfills these specifications.
A few of the essential docs to be checked at this stage are the requirements specification, the blueprints for the design ER diagrams, test cases and scenarios, the traceability matrix, etc.
Verification tests assure that all development elements, including the software, hardware, documentation, and human resources, adhere to organizational and team-specific standards and rules. In addition, it matches well to ensure that the system design and architecture are appropriately planned and have no mistakes.
In the official definition, the phrase is described as being at a certain stage of development. In the development process, a verification test refers to one particular step.
Before the beginning of development, standards, and requirements are specified for every stage in the procedure. Verification testing reviews the software present in the middle of being developed to confirm that it approves to these standards.
Usually, the verification checks are all about learning the specifications and reviewing them next to the code logic. The Code reviews, walkthroughs, inspections, design, and specification analysis are standard elements of verification testing.
When should you make use of Verification Testing?
In order to implement a feature, verification tests must be run at each stage of development.
Consider a button that says “Add to Cart”. As part of the verification process, all the essential requirements previously outlined in the stages of brainstorming and creativity are reviewed.
Let us say that the documentation says that the button should be black with the lettering in white color. It must also be visible continuously on every product page on the website and must not exceed 10mm x 10mm.
One more button with similar text, color, and dimensions must be placed beneath each product on the page.
Before creating the button, design and requirements documents must be checked, and all the necessary specifications should be listed.
Before you ultimately construct the button, the design and requirements documents must be minutely reviewed, and all required specifications must be listed before good work starts. Assure you do this before working on each component or element on the page so that the devs obtain all the guidelines.

What do we mean by Validation Testing?
According to the IEEE-STD-610, validation testing confirms that “An end product stakeholder’s actual conditions and expectations are fulfilled.”
In the same way that verification testing occurs at every stage of development, validation testing occurs at the end of a specific module or sometimes after the building of the software is complete. Its main purpose is to review that the final product is similar to the stakeholder and customer needs.
Most of the QA forms come below this category. A few of the common tests that fall below this heading are:
- Unit Testing
- User Acceptance Testing
- Smoke Testing
- Integration Testing
- Functional Testing
- Performance Testing
- Regression Testing
- Security Testing
- Accessibility Testing
- System Testing
- Cross Browser Testing
In software testing, the following are the main differences between verification and validation:
Let’s explore the differences between validation and verification.
- It is the static art of studying and reviewing the particular requirements of a specific stage in development.
- It doesn’t require the execution of code. Instead, this affects simple human verification of the assets that are needed.
- It utilizes techniques like document reviews, walkthroughs of the product, inspection, and desk checking.
- It’s made for discovering the bugs at the beginning of every development phase.
- The targets are specification documents, software architecture design documents, table design for databases, ER diagrams, database table design, and scenarios, traceability matrix, and similar stuff.
- It’s conducted by the developers and testers to assure that the software follows the previously fixed standards and reactions.
- Its place is before validation testing.
- It doesn’t require devices, browsers, platforms, browsers, or operating systems for its implementation.
- Most software testing companies in India use this method to test the final product after development to ensure it meets customer needs. It just involves executing the code.
- Both human and machine-based checks are involved, as well as software approval.
- The process is about various kinds of product testing– unit tests, integration tests, regression tests, and cross-browser.
- Its purpose is to find all bugs that need to be detected at the verification stage.
- Its main target is the product that the consumer must use after public release.
- It’s mainly conducted by QA engineers with experience who comb through an app’s features to check whether they work correctly.
- It carefully follows verification testing.
- It’s conducted in the best way by making use of real browsers, os, and devices.
- We are utilizing real browsers, devices, and operating systems.
By correctly understanding and using verification and validation in software testing, bugs that would degrade the user experience and result in negative reviews and bad feedback from customers and users can be drained out and neutralized. You won’t have to deal with irrational users downvoting or leaving your application by setting up verification and validation activities.
