### Question:
TenorParameterMetadata implements TenoredParameterMetadata, ImmutableBean, Serializable { public static TenorParameterMetadata.Meta meta() { return TenorParameterMetadata.Meta.INSTANCE; } private  TenorParameterMetadata(
      Tenor tenor,
      String label); static TenorParameterMetadata of(Tenor tenor); static TenorParameterMetadata of(Tenor tenor, String label); @Override Tenor getIdentifier(); @Override TenorParameterMetadata withTenor(Tenor tenor); static TenorParameterMetadata.Meta meta(); @Override TenorParameterMetadata.Meta metaBean(); @Override Tenor getTenor(); @Override String getLabel(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void test_builder_incomplete() { BeanBuilder<? extends TenorParameterMetadata> builder = TenorParameterMetadata.meta().builder(); assertThatIllegalArgumentException() .isThrownBy(() -> builder.build()); }
