What does test code IU stand for?

• A. 100% of Unit
• B. Inspection Unit
• C. Internal Unit
• D. Immediate Unit

Answer: (A)

The test code IU communicates full coverage of a single unit—the entire unit’s functionality is exercised. In practice, this means designing tests that run through all functions, branches, and edge cases within that unit, so nothing within it is left untested. This is why it aligns with the option describing testing 100% of the unit: the scope is complete and self-contained, focusing on the unit in isolation from other parts of the system. The other wording would imply something different: an inspection-type check that doesn’t execute the code, a focus on the unit’s internal aspects rather than its overall tested scope, or a sense of urgency or immediacy that doesn’t pertain to how much of the unit is covered.
