What are examples of non functional requirements?
Some typical non-functional requirements are:Performance – for example Response Time, Throughput, Utilization, Static Volumetric.Scalability.Capacity.Availability.Reliability.Recoverability.Maintainability.Serviceability.More items…•
How do you find non functional requirements?
Non-functional Requirement MetricsTime. Transactions / sec. Response time. … Space. Main memory. Auxiliary memory. … Usability. Training time. Number of choices. … Reliability. Mean time to failure. Downtime probability. … Robustness. Time to recovery. % of incidents leading to catastrophic failures. … Portability. % of non-portable code. Number of systems where software can run.
What is scalability in non functional requirements?
Scalability is a non-functional property of a system that describes the ability to appropriately handle increasing (and decreasing) workloads. … Scalability competes with and complements other non-functional requirements such as availability, reliability and performance.
What does it mean if something is functional?
Use the adjective functional to describe something that is made to do a specific job, such as the functional alarm clock feature on a digital stopwatch. The word functional comes from the Latin word functionem, meaning “performance, execution.” It can also describe whether something is working properly.
How do you gather non functional requirements?
How do you discover and elicit non-functional requirements?Stakeholder goals, values, and concerns – Talk to the stakeholders! … Legacy system and/or existing platform constraints – the analyst takes a look at constraints dictated by the environment into which the new system must fit, the existing systems with which it must integrate, and the technical platform(s) it must use.More items…
What is functional testing example?
Functional testing verifies that the software performs its stated functions in a way that the users expect. The process of functional testing involves a series of tests: Smoke, Sanity, Integration, Regression, Interface, System and finally User Acceptance Testing.
What is recoverability in non functional requirements?
Recoverability: The capability of the software to re-establish its level of performance and recover the data directly affected in the case of a failure. Availability: The capability of the software to be in a state to perform a required function at a given point in time, under stated conditions of use.
What is reliability in non functional requirements?
DEFINITION: Reliability is the extent to which the software system consistently performs the specified functions without failure. ELICITATION: Reliability requirements address the user concern for the system’s immunity to failure.
What is the meaning of non functional requirements?
Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.
What are non functional testing types?
Non-functional testing includes:Baseline testing.Compliance testing.Documentation testing.Endurance testing or reliability testing.Load testing.Localization testing and Internationalization testing.Performance testing.Recovery testing.More items…
What are two types of functional requirements?
Types of Functional RequirementsTransaction Handling.Business Rules.Certification Requirements.Reporting Requirements.Administrative functions.Authorization levels.Audit Tracking.External Interfaces.More items…
What is the difference between functional and non functional testing?
Functional testing verifies each function/feature of the software whereas Non Functional testing verifies non-functional aspects like performance, usability, reliability, etc. Functional testing can be done manually whereas Non Functional testing is hard to perform manually.
What is a functional requirement vs non functional requirement?
While functional requirements define what the system does or must not do, non-functional requirements specify how the system should do it. Non-functional requirements do not affect the basic functionality of the system (hence the name, non-functional requirements).
What are the functional testing types?
Functional Testing Types Unit Testing. i. Smallest functional and testable unit of code is tested during unit testing. … Integration Testing. i. … Interface Testing. i. … System Testing. i. … Regression Testing. i. … Smoke Testing. i. … Sanity Testing. i. … Acceptance Testing.
