This statement is False. A step-by-step procedure for using a test case to test a specific unit of code describes a Test Procedure (or Test Script/Test Case Specification), not a Test Plan. A Test Plan is a higher-level document describing overall testing scope, objectives, approach, resources, schedule, and risks for a project or feature — it doesn't itself contain the granular step-by-step execution instructions. Conflating the two is a common terminology mistake, which is exactly why this statement is marked False.
