Validation & Testing Services
Validation checks that the product design
satisfies or fits the intended usage (high-level checking) — i.e. the product
built is up to the mark or not. This is done through dynamic testing and other
forms of review. In other words, validation ensures that the product actually
meets the user's needs, and that the specifications were correct in the first
place. Validation ensures that ‘you built the right
thing’. Validation confirms that the product, as
provided, will fulfill its intended use.
Validation often is carried out by a separate
group from the development team.
Software testing is an investigation conducted to provide stakeholders with
information about the quality of the product or service under test and checking
the software is working properly or not. Software testing can also provide an
objective, independent view of the software to allow the business to appreciate
and understand the risks of software implementation. Test techniques include,
but are not limited to, the process of executing a program or application with
the intent of finding software bugs (errors or other defects).
Software testing can be stated as the process of validating and verifying that a
Meets the requirements that guided its design and development;
Works as expected;
Can be implemented with the same characteristics.
Software testing, depending on the testing method employed, can be implemented
at any time in the development process. However, most of the test effort occurs
after the requirements have been defined and the coding process has been
completed. As such, the methodology of the test is governed by the software
development methodology adopted.
