________ testing validates the value delivered by an application. (1) User acceptance (2) Usability (3) Showcases (4) All of the options.
Answer: (2) Usability
The value delivered by an application is confirmed by usability. It is necessary to validate the product prior to delivery whenever it comes to the application while providing a product or service to the customer, the quality that is provided is initially assessed and the application is validated at the time of usability. Showcasing the programme or user approval cannot be viewed as validation.
