Valideringstesting

Valideringstesting, also known as verification and validation (V&V) testing, is a critical phase in the software development lifecycle. Its primary purpose is to confirm that a system or application meets the specified requirements and fulfills the intended use for which it was designed. This process ensures that the software not only functions correctly according to its design specifications but also satisfies the needs and expectations of its end-users and stakeholders.

The validation testing phase typically occurs after system testing and before the release of the software. It involves executing the software in an environment that closely mirrors the production setting. This allows for the identification of any discrepancies between the actual performance of the software and its expected behavior, especially in real-world scenarios.

Key activities within validation testing include user acceptance testing (UAT), beta testing, and operational acceptance testing. User acceptance testing focuses on whether the software meets the business requirements and is acceptable to the end-users. Beta testing involves releasing the software to a limited group of external users for feedback on usability and functionality in their own environments. Operational acceptance testing ensures that the software is ready for deployment and operation, covering aspects like security, reliability, and maintainability.

The goal of validation testing is to provide confidence that the software is fit for purpose. By uncovering defects or usability issues that may have been missed in earlier testing stages, validation testing helps to prevent costly errors and ensure customer satisfaction. It serves as the final checkpoint before the software is deployed into the production environment.
