Non Functional Testing in software Testing With Example

Non-Functional Testing?

Non-functional testing is a type of software testing in which we check the non-functional (performance, usability, reliability ) requirements of the application /software. In non-functional testing, we test all the aspects which we are not tested during functional testing.

Non Functional testing is a software testing technique that checks the non-functional attribute of the application (memory leak, usability, performance, the robustness of the system. Non-functional testing is a type of black-box testing.

What do We test in non-functional testing?

In non-functional Testing, we Check that How does the application perform under normal circumstances?
In non-functional Testing, we Check that How does the application behave when too many users log in concurrently?
In non-functional Testing, we Check that, Can the application is able to handle stress?
In non-functional Testing, we Check the security of the application, How secure is the application?
In non-functional Testing, we Check that, Can the application recover from any disaster?
In non-functional Testing we Check the Compatibility of the application, Can the application behave in the same way in a different environment or OS?
In non-functional Testing, we Check How easy is to port the application to a different system?
