Functionality testing of software is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements.

Functionality testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.

Functional vs non-functional testing
Functional testing refers to tests that verify a specific action or function of the code. These are usually found in the code requirements documentation, although some development methodologies work from use cases or user stories. Functional tests tend to answer the question of "can the user do this" or "does this particular feature work".
Non-functional testing refers to aspects of the software that may not be related to a specific function or user action, such as scalability or security. Non-functional testing tends to answer such questions as "how many people can log in at once"
