This approach is essential for anyone looking to excel in modern software development and quality assurance roles.
Key Differences Between Validation And Verification
When it comes to software testing, both Validation and Verification are the parts of the V model where the development & testing activity begins based on requirement specification documents. The two independent processes, when put together and implemented accurately, can make sure that your software has been delivered without any defaults.
But, what is the actual value that they bring to the table on an individual level? Let’s start with the basics, then move on to the table representing the primary difference between the two-
What is Validation in Software Testing?
Validation is essentially dynamic testing that is done to verify whether the product is built in a way that best addresses consumer needs and wants. Any and every software is only successful when it is capable of performing well in the ideal environment.
Unit testing, integration testing, system testing, user acceptance testing – these are all a part of the validation process in software testing. In simpler words, it is a process of validating the software and verifying whether it checks all the requirement boxes or not.
What is Verification in Software Testing?
Verification is the process of static testing where you ask yourself – is the product that I am developing is right or not? It verifies whether the developed product fulfills the requirements that are a part of the brief document. It also involves the process of checking that a software achieves its goal without any bugs.
This is where the Quality Assurance team checks the documents, design, code, and program – all to verify if the software has been built accurately. The quality assurance of software application, design, architecture, etc. is also done during this phase.
| Verification | Validation |
| Verification is the static testing process. It takes place in the development phase to find out whether the software meets the specified requirements or not. | Validation is dynamic testing. It takes place at the end of the development process to determine whether the software meets the customer’s expectations and requirements or not. |
| As the name suggests, it is a verifying process that includes checking documents, design, codes, and programs. | It is the process of dynamically testing and validating the actual software that has been built. |
| This is where reviews of specification and product development, walkthroughs, desk-checking, and meetings about diversification and inspections happen. | This is where different types of testing such as Black Box Testing, White Box testing, Grey box testing, non-functional testing are conducted. |
| Verification, being static testing, does not concern itself with the execution of code. | Validation, being dynamic testing, always involves executing the necessary code. |
| The detection of bugs is done quite early in the development cycle. | The process of Validation helps detect bugs that could have gone unnoticed during the Verification process. |
| Here, the target is application and software architecture, specification, complete design, high level, and database design. | Here, the target is the actual, completed product. |
| Verification is carried out by the Quality Assurance (QA) team to make sure that the software is as per the requirement in the SRS document. | Validation is expertly executed on software code with the help of the testing team. |
| Verification is carried out before the Validation. | Validation activity is carried out just after the Verification. |
| It is performed by a team of human experts. | It is performed by the computer. |
