Verification and Validation in Software Testing: Diving Into The Core Of Software Testing

Verification and Validation are the two most popular terms in Software Testing. However, most newbies who have started their career with development and IT operations tend to find it very confusing during the initial stages of their career. 

However, verification and validation are two of the most important aspects of the software testing process that needs to be worked for ensuring best out of Software testing and QA services. In this blog, we will help you know the meaning of individual terms first (like, what is Verification & Validation in Software Testing?). Also, we will help you understand the exact difference between Verification and Validation with Examples in order to help you have better insights of these terms.  

Let’s begin! 

What is Verification in Software Testing?  

In Software Testing, Verification is the process of evaluating the intermediary work products of a software development lifecycle. It helps us check whether we are on the right track of creating the final product or not. In other words, we can understand that verification is the process of assessing the mediator products of software to check whether the products meet the conditions set forth at the start of the phase.   

Mediator or Intermediary Products  

The mediator or intermediary products are those products that include the documents which are created during the development phases, such as requirements specification, design documents, ER diagrams, database table design, test cases, traceability matrix, etc.  

Thus, reviewing these documents as a part of Verification in Software Testing is necessary because it helps find out various hidden anomalies and makes it possible for testers to fix them in the earlier phase of the development cycle. In case of finding such hidden anomalies later, one can experience the high cost in the development cycle.   

The purpose of verification is to ensure that the system from Software, Hardware, Documentation to Personnel comply with a company’s standards and processes and make it feasible for them to review or use non-executable methods.   

What is Validation in Software Testing?  

The process of assessing the final product to check whether the software satisfies the business needs is known as Validation in Software Testing. In the layman’s language, the tests we execute in our daily life are actually the validation activity, including various types of tests from Smoke Testing, Regression Testing, Functional Testing, and many more. Moreover, you can understand that Validation covers all types of testing to check how the product works and put it to the test so that consumers can get the best quality product later.   

Some of the validation techniques that we use in Software Testing are:   

  • Unit Testing  

  • Integration Testing  

  • System Testing  

  • User Acceptance Testing  

Besides, Validation aims to ensure that the system works based on a plan by implementing the system functions via a series of tests that can be viewed and evaluated.

Examples of Verification & Validation in Software Testing   

Imagine you visit any restaurant, and you have ordered a cheese burst pizza. Now the waiter comes to you with your order, but how can you judge that the food that came out is made as per your order?  

The answer is: you may check the following things to confirm that it is actually a cheese burst pizza.   

  • You may check the loaded cheese in your pizza.   

  • You may check a thick crust with yummy liquid or molten cheese inside.   

  • Is its fragrance seem right?  

  • Are the toppings to be seen?  

On the flip side, when you get sure that the food that you’ve ordered is as expected and you will have to eat it, is the process of Validation in Software Testing.   

All in all, anything that you check or first review the subject is the case of Verification. However, validation is the method to eat or use the product to see whether it is correct or not.   

Distinction Between Verification and Validation in Software Testing 

Verification  

Validation  

Analyses the intermediary products to check whether it meets the specific requirements of the particular phase or not. 

Evaluates the final product to check whether it fulfills the business needs or not.  

Confirms whether the product is developed based on the design specification and the specified requirement.  

It confirms whether the software is suitable for use and meets the business needs. 

Verifies “are we building the product right”? 

Validates “are we building the right product”? 

Verification is done without the execution of software. 

Execution of software is crucial.  

It includes almost all types of static testing techniques.  

It covers dynamic testing techniques.  

Examples involve reviews, inspection, and walkthroughs.  

Examples involve different types of testing from functional, smoke, regression to user acceptance testing.

When to Consider Verification and Validation in Software Testing   

Undoubtedly, these are two independent terms in Software Testing. However, when it comes to checking the system or application complies with the requirements and specifications and helps achieve the intended purpose, we combine Verification and Validation together in Software Testing because both of them are critical components of the quality management system.   

Make sure sometimes, the product is easy to pass through the verification, but it fails in the validation phase. This happens because, in Verification Testing, one has to meet the documented requirements and specifications. On the other hand, those specifications or standards don’t help to fulfill the unique user needs.  

Therefore, choosing the independent Verification & Validation Testing Services is essential from the Software Testing Company to assure that the software, system, or product fulfills the major requirements and pre-determined goals or objectives.   

At BugRaptors, we have the Next-Generation Test Center of Excellence and deal with various industry verticals to help them achieve their quality goals through best QA practices and Independent Verification & Validation (V&V) Services. With our Independent Verification & Validation (V&V) services, you can have an easy-to-get competitive advantage because our 250+ certified professionals have expertise in world-class processes and cutting-edge technologies to help you deliver the desired results and satisfy the V&V requirements at each stage of the product life cycle.

Conclusion   

Verification & Validation are two separate terms in Software Testing as Verification is used as an internal process in development for scaling or production. Whereas one should involve Validation in the external process to make the product best fit for stakeholders. All in all, V&V (Verification & Validation) Testing Services determine whether a specific activity of product meets the requirements are suitable for its intended purpose.
