Unit 5 Wrap-Up: What Did the Test Actually Establish?

Use your Component Test Record. Respond in 75–125 words or make an equivalent one-minute recording. Use at least two exact labels from your artifact, such as continuesExactlyAtBoundary, 0.50 m, IllegalArgumentException, /sensor_bridge, or 0.42 m.

1. Which test gave you the strongest evidence about an important boundary, and what exact behavior did it establish?
2. What changed after the deliberate <= defect failed and you repaired the implementation?
3. What remains uncertain even after the JUnit tests and ROS 2 graph observation are both available?
