suresh What is the difference between functional testing and non-functional testing in software testing?
Functional testing and non-functional testing are two different types of software testing methodologies that serve different purposes in ensuring the quality of a software product.
Functional Testing:
Functional testing focuses on verifying that the software application functions as expected and meets the specified requirements. It involves testing individual functions and features of the software to ensure they work correctly. This type of testing is primarily concerned with what the software does.
Non-Functional Testing:
Non-functional testing, on the other hand, focuses on evaluating the performance, scalability, reliability, and other non-functional aspects of the software. It tests how the software performs under various conditions and its ability to meet performance benchmarks. This type of testing is primarily concerned with how well the software performs.
In summary, functional testing ensures that the software functions correctly, while non-functional testing evaluates the performance and other non-functional aspects of the software.
Both types of testing are essential for ensuring the overall quality and reliability of a software product.
When conducting software testing, it is important to consider both functional and non-functional aspects to ensure the software meets the needs and expectations of its users.
