Difference Between Verification and Validation Testing? An Explainer

Automation Testing with cucumber framework - Although verification and validation may appear to be synonymous, there are significant differences between the two phrases. Are you fulfilling the demands and expectations of the customer? Does the software meet the criteria that you and your team have established? In this article, we'll go in-depth on the distinctions between validation and verification, their respective uses and benefits, and how Perfecto's advanced testing platform makes it simple for your team.

What exactly is a verification test?

Teams use verification testing, commonly referred to as static testing, to ascertain whether their application complies with the stated design and development criteria. The documentation, code, design, and program are among these requirements.

Verification testing should be used periodically throughout the development process, just like in continuous testing. Verification tests must be run repeatedly since they each examine a particular aspect of the program as it is being developed. This guarantees that the final output complies with the requirements set at the beginning of the project.

Specification analysis, design and code reviews, walkthroughs, and inspections are a few examples of verification testing.

Verification testing advantages

You can gain the following advantages by using verification testing as a strategy in the development of your application:

Less rework and duplicate work is produced by maintaining close alignment with stakeholders' expectations at every level of development.
gaining a deeper understanding of the project's diverse needs as development goes forward.
lowering the number of errors and bugs that surface at later phases of development.
establishing a framework to assist QAs in estimating and getting ready to manage such bugs and faults as they arise.

Validation testing: what is it?

The phase of the development process known as validation testing, or dynamic testing, checks to see if the application satisfies the demands and specifications of the relevant stakeholders. In a nutshell, validation makes sure the application is suitable for user requirements.

Asking yourself whether this application functions as intended is the simplest way to approach validation testing.

Function and non-functional testing make up validation testing, which is done at the end of the development cycle to evaluate the finished product and determine whether it complies with the requirements for use by the general public.

The advantages of validation testing

Validation testing during the last stages of creating your application can mean:

assurance that the product complies with the needs, tastes, and expectations of the consumer under different circumstances.
information about bugs that were missed during the verification testing stage.
assurance based on cross-browser testing that the program works flawlessly regardless of the device or browser.
before the program is released to the market, identifying inaccurate specs or defective designs.

Verification and Validation in Testing: When to Use Them

When they are employed in the SDLC is the main distinction between verification and validation testing. Despite the fact that they complement one another, one must come before the other in testing.

Before finalizing any aspect of the application, verification tests should be conducted at each level of the SDLC, as was previously indicated. That is to make sure you are not using a glitchy or broken feature.

Assume, for instance, that you are developing an online store. A "Save to Wish List" option is needed for product pages. When you click on this feature, which appears as a heart, it animates and verifies that the item has been added to your wish list.

To make sure all the rules are created, you would check all the paperwork and pertinent requirements using verification testing. The team would then check to see that the "Save to Wish List" button was placed correctly on the page, that the heart was animated and was the appropriate shade of red as stated in the original documentation, and that adding the item to your wish list actually took place.

Validation Examination

Consider validation testing as a last check before you mark the box next to a certain application feature. It is now time to test the functionality of the initial design and coding components, which are all in place. Unit testing, which is carried out after each piece of code has been written, is a typical validation test.

Cross-browser testing, which allows you to check whether your "Save to Wish List" feature functions identically on an iPhone 11 and a Samsung Galaxy S23, is a crucial component of validation testing. When your product is put through validation testing, it is determined whether or not the consumer will find it acceptable; a key factor in determining whether the functionality is compatible with all devices and operating systems - Automation Testing with Python
