To answer this question, you need to understand the different levels of testing and their purposes.
Option A) Master Test Plan - This option is incorrect because a Master Test Plan typically describes the overall testing approach for a project, including the different types and levels of testing. It is not specific to establishing confidence in the system.
Option B) System Test Plan - This option is incorrect because a System Test Plan typically focuses on testing the entire system as a whole, ensuring that all the components work together correctly. While confidence in the system may be a goal of system testing, it is not the primary goal.
Option C) Acceptance Test Plan - This option is correct because an Acceptance Test Plan is specifically written to describe a level of testing where the primary goal is establishing confidence in the system. Acceptance testing is typically performed to ensure that the system meets the requirements and is ready for production use.
Option D) Project Plan - This option is incorrect because a Project Plan typically outlines the overall plan and objectives for a project, including activities such as resource allocation, timelines, and deliverables. It is not specific to establishing confidence in the system.
The correct answer is C) Acceptance Test Plan. This option is correct because it specifically describes a level of testing where the primary goal is establishing confidence in the system.
