The software penetrates into almost all spheres of human life and exists in numerous devices that have already entered our everyday lives. It leads every our step - it's a part of everything that we do, everything that affects us, and everything surrounds us. It definitely makes our everyday lives easier, but it’s filled with bugs. It doesn't matter whether the bug appeared due to lack of developer skills, survived after long hours of searching, or was considered to be a hidden feature.
Software testing can be divided into two types by the object of testing: functional and non-functional testing.
Functional testing - software testing aimed at testing the feasibility of functional requirements. During functional testing, the ability of the software to properly perform the tasks required by users is tested.
Non-functional testing of software is first of all a check for compliance with non-functional requirements: convenience, productivity, security, portability, and reliability.
