To answer this question, you need to understand the different types of testing in software development.
Option A) Black box testing - This option is incorrect. Black box testing is a method of testing where the tester does not have knowledge of the internal workings of the system. It focuses on testing the functionality and behavior of the system from a user's perspective. It does not specifically address the demonstration of system compliance with user requirements.
Option B) System testing - This option is incorrect. System testing is a type of testing that verifies the behavior and functionality of the entire system as a whole. It is performed to ensure that all the components of the system work together as expected. While system testing may include testing for compliance with user requirements, it is not specifically focused on demonstrating system compliance.
Option C) Independent testing - This option is incorrect. Independent testing refers to testing conducted by a third party or external entity that is not directly involved in the development of the system. It aims to provide an unbiased assessment of the system's quality. However, it does not specifically address the demonstration of system compliance with user requirements.
Option D) Acceptance testing - This option is correct. Acceptance testing is a type of testing that is conducted to determine whether a system meets the specified acceptance criteria and is ready for deployment. It involves testing the system against user requirements to demonstrate compliance. Acceptance testing is typically performed by the end-users or stakeholders to ensure that the system meets their needs and expectations.
The correct answer is D) Acceptance testing. This option is correct because acceptance testing specifically focuses on demonstrating system compliance with user requirements.
