- Choose between fixed collection iteration and condition-controlled repetition.
- Initialize and update counters and accumulators exactly once per qualifying item.
- Trace each iteration and identify off-by-one or non-terminating behavior.
- Verify a loop with empty, one-item, ordinary, and stopping-boundary cases.
