Which of the following characteristics is applicable to a master test plan?

A master test plan serves as a comprehensive document that outlines the overall testing strategy for a project. It encompasses high-level details about what the testing process will involve, including the scope, approach, resources, schedule, and estimated costs involved in testing.

The choice that highlights the overall estimated costs, timescales, and resource requirements is particularly relevant because it captures the essence of what a master test plan aims to provide. It helps manage stakeholder expectations by giving a complete view of how much time and resources will be needed to accomplish the testing objectives, allowing for better planning and allocation of resources throughout the development cycle.

On the other hand, focusing on detailed schedules of testing activities or specific test cases for each module falls more into the realm of detailed or specific test planning documents rather than the overarching master test plan. The master test plan should provide a big picture rather than delve into granular details about individual testing phases or the specific test cases.
