non functional testing in software testing

This is contrast to functional testing, which tests against functional requirements that describe the functions of a system and its components. On the other hand, non-functional testing performs checks on wider quality concerns, verifying all non-functional aspects of the software application (such as . Recovery Testing:Evaluates how well the system recovers from crashes, hardware failures, or other catastrophic incidents. Security testing is a type of non-functional testing that focuses on identifying and resolving issues in the software that could allow unauthorized access or damage. We conduct non-functional testing to make sure that the interests of the end-user are respected. Non-functional testing is defined as a type of software testing to check non-functional aspects of a software application. Functional Testing verifies that each function of the software application operates in conformance with the requirement specification.Functional testing is a quality assurance (QA) process and mainly involves Black Box Testing.It is concerned about the results of processing and not about the source code of the application. Functional testing focuses on the functionality of the software, while non-functional testing focuses on aspects such as performance and stability. Availability testing: It's a type of non-functional testing and we check whether our application is up and running or not. Performance Testing . The ease with which the user can learn, operate, prepare inputs and outputs through interaction with a system. The flexibility of software to transfer from its current hardware or software environment. In addition, this testing is designed to test a system's readiness related to non-functional parameters typically never addressed by the functional testing process. Functional testing, typically performed manually, verifies that a program or apps operational execution happens as set down by the business and technical requirements. These systems provide redundancy for critical systems, allowing them to continue running even if one system fails. Or does the application behave differently in another operating system or environment? OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. The following are the objectives of non-functional testing: Non-functional testing possesses a unique set of characteristics: These are the eleven parameters found in non-functional testing.
