"Enhanced test coverage" in automated testing means:

1. _Comprehensive testing_: Automated tests can cover a wider range of test cases, including edge cases and corner cases.

2. _Increased test scope_: Automated tests can cover more features, functions, and scenarios, ensuring thorough testing.

3. _Improved test depth_: Automated tests can perform more in-depth testing, exercising devices more thoroughly.

4. _Broader test range_: Automated tests can cover a wider range of inputs, outputs, and environmental conditions.

5. _More test iterations_: Automated tests can run multiple iterations, ensuring devices operate correctly under repeated stress.

6. _Better error detection_: Enhanced test coverage improves defect detection, reducing the likelihood of errors slipping through.

7. _Reduced test gaps_: Automated testing minimizes test gaps, ensuring devices are more thoroughly tested.

8. _Increased confidence_: Enhanced test coverage increases confidence in device functionality and reliability.

By covering a wider range of test cases and scenarios, automated testing provides more comprehensive testing, ensuring devices operate correctly and reliably in various situations.
