### Question:
BasicRateMeasurement extends BasicMeasurement implements RateMeasurement { @Override public boolean isComplete() { return super.isComplete() && d_rate != null && d_rate > -1 && d_rate <= d_sampleSize; } BasicRateMeasurement();  BasicRateMeasurement(Integer rate, Integer total); String getLabel(); @Override String toString(); void setRate(Integer rate); Integer getRate(); boolean isOfType(VariableType type); @Override boolean equals(Object o); @Override int hashCode(); @Override BasicMeasurement clone(); @Override boolean isComplete();  }### Answer:
@Test public void testIsComplete() { assertTrue(d_measurement.isComplete()); BasicRateMeasurement m1 = new BasicRateMeasurement(0, null); assertFalse(m1.isComplete()); BasicRateMeasurement m2 = new BasicRateMeasurement(null, 5); assertFalse(m2.isComplete()); BasicRateMeasurement m3 = new BasicRateMeasurement(0, 0); assertFalse(m3.isComplete()); BasicRateMeasurement m4 = new BasicRateMeasurement(0, -1); assertFalse(m4.isComplete()); BasicRateMeasurement m5 = new BasicRateMeasurement(-1, 5); assertFalse(m5.isComplete()); BasicRateMeasurement m6 = new BasicRateMeasurement(5, 4); assertFalse(m6.isComplete()); }
