Validation and verification are an integral part of software testing. Verification is the technique to evaluate the software development's artefacts, which assures that the product which is developed complies with different standards.
It is a static process to analyze different documents. Validation,
on the other hand, contributes to being the process to validate that the
developed software product is conformed to the different needs of the business.
It executes software product's dynamic testing.
Validation in the software
testing
Validation in QA services contributes to being
the dynamic mechanism to test and validate whether the actual software product
accomplishes the potential audience's requirements. Besides this, this process
assures that the software accomplishes the prerequisite desired use within the
appropriate environment. This validation process includes different activities,
such as integration testing, unit testing, user acceptance testing, and system
testing.

Key differences
·
The verification process is inclusive
of the checking of the code, design, documents and program. On the other hand,
the validation process is inclusive of the validation and testing of the real
product.
·
Verification does not include
the execution of the code. On the other hand, validation involves the execution
of the code.
·
Verification makes use of
different methods, such as walkthroughs, reviews, desk checking and
inspections. However, validation makes use of different techniques, such as
white box testing, black-box testing, and non-functional testing.
·
Verification is useful in
checking if the specific software confirms the specification. On the other
hand, validation helps in checking if the software accomplishes different
expectations and requirements.
·
Verification offers a helping
hand in finding the bugs and errors during the development cycle. On the other
hand, validation is useful in finding different errors and bugs, which cannot
be caught during the process of verification.
·
The verification process is
known to target software design, architecture, database, to name a few. The
validation process, on the other hand, targets the real software product.
·
The Quality Assurance Team
performs the verification process. However, the testing team, in combination
with the Quality Assurance Team, accomplishes the validation process.
·
The process of verification
starts before the process of validation. The validation process, on the other
hand, follows the verification process.
Key differences between validation and verification in software testing
In this part, you can find the crucial differences between
validation and verification within the software testing:
·
Validation contributes to being
the dynamic process to test and validate the specific product. However, the
verification process is inclusive of the checking of the code, design,
documents, and program.
·
Validation, on the other hand,
includes code execution. In the verification, on the other hand, you do not
need to perform the code.
·
Validation makes use of
different processes, such as white box testing, black-box testing,
non-functional testing. On the other hand, verification uses different
techniques, such as walkthroughs, reviews, desk-checking, and inspections, to
name a few.
·
On the other hand, validation
helps in checking if the software accomplishes the expectations and needs of
the potential audience. In verification, you need to find if the software
conforms to the checked specification.
·
Validation happens to be a
process that helps find the bugs, which the verification process cannot catch.
Verification, however, is effective in finding the bugs and errors during the
earlier phase of the development cycle.
·
In validation, the target
happens to be an actual product. However, in verification, the target happens
to be the application and software architecture, complete design,
specification, database design, high level, to name a few.
·
Validation includes the
validation of the software testing team, which is run on the software code. The
quality assurance team performs verification, thereby assuring that the
software is according to the SRS document's needs.
Validation is followed by
verification, whereas verification comes before the process of validation.
Validation helps in determining whether the specific system complies
with different needs. It is known to execute the functions; for the process, it
is meant it. It accomplishes the user needs and objectives of the business
organization.
Validation is performed at the last part of the development process,
after which it takes place after the completion of the verification. Validation
happens to be a high-level activity. Validation is executed after the work
product gets generated against the established criteria. It assures that the
product gets integrated into the environment properly.
As per the CMM or Capability Maturity Model, you need to define the
validation. It contributes to evaluating the specific software at the end part
or during the software development process. It helps in determining if it
satisfies certain needs. During verification, as certain defects get missed, it
is referred to as failures during the process of validation.
Validation is performed during the testing, such as integration
testing, feature testing, load testing, system testing, stress testing, and
compatibility testing, to name a few. Validation helps in developing the right
product according to the needs of the potential audience. It also accomplishes
the requirements of the customer.
It is possible to perform the validation by the software testers
during the process of software testing. Validation is useful in unfolding the
feature's exact functionality. It is useful to the software tester in gaining
an understanding of the product properly. It is useful in making the specific
product user-friendly.
Summary
Verification plays an integral role in the evaluation of the
intermediatory products, which helps in checking if it is accomplishing the
needs of the specific phase. Validation, however, helps in evaluating the final
product, which helps in checking whether it accomplishes the needs of the
business.
Validation helps in determining if the software is fit for use,
thereby satisfying the needs of the business. On the other hand, verification
helps in checking if the product is built according to the design specification
and specified requirement.
Validation is accomplished
with the running of the software. However, it is possible to perform the
validation with software execution. Verification, on the other hand, is
accomplished without running the software. Validation is inclusive of different
kinds of dynamic testing processes. However, verification comes with a variety
of static testing processes.
