Which statement best describes the contents of a comprehensive test plan?

• A. A step-by-step guide for executing tests.
• B. A summary of user requirements.
• C. A document outlining scope, objectives, features tested, resources, schedule, risk, acceptance criteria, and test cases.
• D. A log of defects found during testing.

Answer: (C)

A comprehensive test plan is a blueprint for testing that lays out what will be tested, how testing will be performed, when it will happen, and who is responsible, along with the criteria used to judge success. It defines scope and objectives to set boundaries and goals, lists features tested to indicate what areas are in scope, and includes test cases that describe the specific inputs, actions, and expected results to validate behavior. It covers resources and responsibilities so the team knows who does what and what environments or tools are needed, and it sets a schedule with milestones. Risk assessment highlights potential blockers and priorities, and acceptance criteria specify what must be true for the product to be considered ready. This collection of elements provides a single, actionable plan that guides testers and stakeholders throughout the testing lifecycle.

The other options don’t fit as well because a step-by-step guide for executing tests focuses on how to perform tests, not what to test and how success is defined; a summary of user requirements describes what the system should do rather than how testing will be planned and measured; and a log of defects is a post-testing artifact used to track issues, not the plan itself.
