The functional requirements document (FRD) is a formal statement of an application's functional requirements. It serves the same purpose as a contract. The developers agree to provide the capabilities specified. Designing and developing tile application system.
Consequently, what do you mean by functional requirements?
In software engineering and systems engineering, a functional requirement defines a function of a system or its component, where a function is described as a specification of behavior between outputs and inputs. As defined in requirements engineering, functional requirements specify particular results of a system.
What are examples of non functional requirements?
Some typical non-functional requirements are:
- Performance – for example Response Time, Throughput, Utilization, Static Volumetric.
What is the difference between functional and non functional testing?
The non Functional Testing is the type of testing done against the non functional requirements. Most of the criteria are not consider in functional testing so it is used to check the readiness of a system. Basically in the non functional test is used to major non-functional attributes of software systems.
