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.
What are non-functional requirements types of testing?
7 Types of Non Functional Testing
- Performance Tests.
- Load Tests.
- Stress Tests.
- Volume Tests.
- Security Tests.
- Upgrade & Installation Tests.
- Recovery Tests.
How do you classify non-functional requirements?
These can can be classified as :
- Performance constraints – Reliability, security, response time, etc.
- Operating constraints –
- Interface constraints –
- Economic constraints –
- Lifecycle requirements – Quality of the design:
How do you find non-functional requirements?
Non-functional Requirement Metrics
- Time. 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.
Is performance a non-functional requirement?
System performance is the most important quality in non-functional requirements and affects almost all the other preceding ones. Furthermore, reliability, availability, and maintainability (RAM) features fall exclusively under these requirements.
How do you find Non-Functional Requirements?
What is a valid non functional requirement?
Functional requirements apply to the specific behaviors of a system, whereas non-functional requirements form measurable criteria that can be used to gauge the success of an overall system, solution, or product.
