Kerfisprófanir, or System Testing, is a crucial phase in the software development lifecycle. It involves evaluating the complete and integrated software system to ensure it meets specified requirements. This stage comes after unit testing and integration testing, where individual components and their interactions have been verified. The primary goal of system testing is to validate the system's compliance with both functional and non-functional requirements.

Functional testing within system testing ensures that the software performs its intended tasks correctly. This includes verifying all features, workflows, and business logic as defined in the requirements documentation. Non-functional testing, on the other hand, assesses aspects like performance, security, usability, reliability, and scalability. For example, performance testing might measure how quickly the system responds under various load conditions, while security testing aims to identify vulnerabilities.

System testing is typically performed by an independent testing team, separate from the development team, to provide an unbiased assessment. Various testing techniques can be employed, including black-box testing, where the internal structure of the system is unknown to the tester, and white-box testing, where the internal workings are understood. The outcome of system testing provides a comprehensive view of the system's quality and readiness for deployment. Defects identified during this phase are reported, fixed by developers, and then retested to ensure resolution. Successful system testing increases confidence in the software's ability to function as expected in a production environment.
