                        Object actuals)
                 throws ArrayComparisonFailure
```

    Parameters:
    message - the identifying message for the AssertionError ( null okay)
    expecteds - Object array or array of arrays (multi-dimensional array) with expected values.
    actuals - Object array or array of arrays (multi-dimensional array) with actual values
    Throws:
    ArrayComparisonFailure
  - assertElementsEqual
