What is Validation Testing: Definition, Phases & Types!

What is Validation Testing?

The definition of validation testing in software engineering is in place to determine if the existing system complies with the system requirements and performs the dedicated functions for which it is designed along with meeting the goals and needs of the organization. This mode of testing is extremely important especially if you want to be one of the best software testers. The software verification and validation testing is the process after the validation testing stage is secondary to verification testing.

Why is Validation Testing Important? 

Validation testing holds significant importance for software development projects.

1. Requirement Compliance: It ensures that the software meets specified requirements, ensuring accuracy, functionality, and performance align with the intended purpose.
2. User Satisfaction: Validation testing aligns the software with user expectations and needs, leading to improved customer satisfaction.
3. Risk Mitigation: Thorough testing reduces the chances of software failures, security vulnerabilities, and usability issues, mitigating potential risks.
4. Regulatory Compliance: Validation testing helps ensure adherence to industry-specific regulations and standards.
5. Cost and Time Efficiency: Early validation testing reduces costs and time spent on fixing issues later in the development process.

Whenever any particular software is tested then the main motive is to check the quality against the defects being found. The developers fix the bugs and the software is rechecked to make sure that absolutely no bugs are left out in that. This not only shoots the product’s quality but also its user acceptance.

Putting Further Emphasis

The point of programming testing is to quantify the nature of programming as far as various deformities found in it, the number of tests run and the framework secured by the tests. At the point when bugs or deformities are found with the assistance of testing, the bugs are logged and the development group fixes them.

When the bugs are fixed, testing is repeated in order to guarantee that they are for sure fixed and no new imperfections have been presented in the product. With the whole cycle, the nature of the product increments.

Now that we have explored the basics and importance of validation testing along with its emphasis on an industrial and user level, let us further explore the phases and stages that are involved in churning out a plan for validation testing.

What are the Phases of the Validation Testing Process?

1. Define Requirements– Mapping out the plan for the requirement gathering process. This will not only include planning out the entire process beforehand but also mapping out the exact requirements that are needed.

2. Team Selection– To get a qualified, knowledgeable, and skilled team onboard. The team selection process involves selecting the individuals as per their past capacity and technical tuning so that they can easily attune themselves to the nature of the bug.

3. Maintaining Documentation– Any form of testing requires voluminous user specification documentation along with several release cases, test cases, and manuals that have to be jolted down so that they are no confusion even in case of an exit of any core member of the team.

4. Validation Report– The software is evaluated as per user specifications and a proper validation report is submitted in order to cross-check the evaluations along with getting an estimated date and round-off for the bug removal and for the system to start functioning properly.

5. Incorporation of changes–Incorporate the changes that have been validated in the last stage.

What are the Types of Validation Testing?

Validation testing types a V-shaped testing pattern, which includes its variations and all the activities that it consists of are:

Unit Testing – It is an important type of validation testing. The point of the unit testing is to search for bugs in the product segment. Simultaneously, it additionally confirms crafted modules and articles which can be tried independently.

Integration testing -This is a significant piece of the validation model wherein the interaction between, where the association between the various interfaces of the pertaining component is tried. Alongside the communication between the various pieces of the framework, the connection of the framework with the PC working framework, document framework, equipment, and some other programming framework it may cooperate with, is likewise tried.

System testing – System testing is done when the whole programming framework is prepared. The principal worry of framework testing is to confirm the framework against the predefined necessities. While doing the tests, the tester isn’t worried about the internals of the framework however checks if the framework acts according to desires.

User acceptance testing – During this testing, the tester actually needs to think like the customer and test the product concerning client needs, prerequisites, and business forms and decide if the product can be given over to the customer or not.


Validation testing techniques are mainly about analyzing the in-depth functionalities of the software product. The validation tester is all about reporting the deviations by precision in order to obtain the maximum possible results. Each and every test case should be sharply written along with broadening the scope of understandability.

If you desire to assess the compliance of your software with specific requirements, undertaking verification and validation testing becomes imperative. Through the stages of v&v testing during the development process, an in-depth analysis of your requirements is performed.
