Functional Testing And Non Functional Testing

Functional testing and non-functional testing are two different types of software testing that are focused on different aspects of the software:

Functional Testing: Functional testing is a type of software testing that is focused on ensuring that the software application or system functions as intended and meets its specified requirements. It involves testing the software against the functional specifications or requirements, and checking that all the expected functionalities are working correctly. Examples of functional testing include unit testing, integration testing, system testing, and acceptance testing.

Non-functional Testing: Non-functional testing is a type of software testing that is focused on evaluating the performance, reliability, usability, and other non-functional aspects of the software application or system. It involves testing the software against non-functional requirements, such as performance, scalability, security, usability, and compatibility, and checking that it meets the necessary standards and expectations. Examples of non-functional testing include performance testing, security testing, usability testing, and compatibility testing.

To summarize, functional testing is focused on ensuring that the software meets its specified functional requirements, while non-functional testing is focused on evaluating the performance, reliability, usability, and other non-functional aspects of the software. Both types of testing are important for ensuring that the software is of high quality, and meets the needs and expectations of its users.
