### Question:
FixedRateComputation implements RateComputation, ImmutableBean, Serializable { public static FixedRateComputation of(double rate) { return new FixedRateComputation(rate); } private  FixedRateComputation(
      double rate); static FixedRateComputation of(double rate); @Override void collectIndices(ImmutableSet.Builder<Index> builder); static FixedRateComputation.Meta meta(); @Override FixedRateComputation.Meta metaBean(); double getRate(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void coverage() { FixedRateComputation test = FixedRateComputation.of(0.05); coverImmutableBean(test); }
@Test public void test_serialization() { FixedRateComputation test = FixedRateComputation.of(0.05); assertSerialization(test); }
