### Question:
DefaultIntervalLength extends DefaultDuration implements IntervalLength { @Override public Unit getUnit() { return unit; } DefaultIntervalLength(final Unit unit, final int radix, final int factor, final int value); @Override Unit getUnit(); @Override int getRadix(); @Override int getFactor(); @Override int getValue(); @Override long getTimeInMillis(); @Override boolean equals(final Object object); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testGetUnit() { Unit result = intervalLength1.getUnit(); assertFalse(intervalLength2.getUnit().equals(result)); }
