Task 3

Functional testing and non-functional testing are two types of software testing. The difference between them are:

Functional Testing:
This type of testing focuses on verifying that the software functions according to its specified requirements. It checks whether the application performs its intended functions correctly. It mainly deals with the "what" aspect of the software.

     It primarily involves testing the features and functionalities of the software. This includes testing individual functions, user interfaces, data processing, and interactions between different parts of the software.

Non-Functional Testing:
Non-functional testing, on the other hand, assesses the qualities or characteristics of the software, such as performance, reliability, usability, and scalability. It evaluates how well the software performs its functions under various conditions and measures attributes like speed, security, and user-friendliness. Non-functional testing deals with the "how" aspect of the software.

     It covers a broader range of attributes and characteristics beyond the core functionality. Non-functional testing includes areas like load testing, security testing, usability testing, and performance testing.

In summary, functional testing focuses on verifying that the software's features work as intended, while non-functional testing assesses various quality attributes like performance, security, and usability. Both types of testing are essential to ensure a software application meets its functional requirements and provides a satisfactory user experience.
