### Question:
CrossGammaParameterSensitivities implements FxConvertible<CrossGammaParameterSensitivities>, ImmutableBean, Serializable { public static CrossGammaParameterSensitivities empty() { return EMPTY; } @ImmutableConstructor private  CrossGammaParameterSensitivities(List<? extends CrossGammaParameterSensitivity> sensitivities); private  CrossGammaParameterSensitivities(ImmutableList<CrossGammaParameterSensitivity> sensitivities); static CrossGammaParameterSensitivities empty(); static CrossGammaParameterSensitivities of(CrossGammaParameterSensitivity sensitivity); static CrossGammaParameterSensitivities of(CrossGammaParameterSensitivity... sensitivities); static CrossGammaParameterSensitivities of(List<? extends CrossGammaParameterSensitivity> sensitivities); int size(); CrossGammaParameterSensitivity getSensitivity(MarketDataName<?> name, Currency currency); CrossGammaParameterSensitivity getSensitivity(
      MarketDataName<?> nameFirst,
      MarketDataName<?> nameSecond,
      Currency currency); Optional<CrossGammaParameterSensitivity> findSensitivity(MarketDataName<?> name, Currency currency); CrossGammaParameterSensitivities combinedWith(CrossGammaParameterSensitivity other); CrossGammaParameterSensitivities combinedWith(CrossGammaParameterSensitivities other); @Override CrossGammaParameterSensitivities convertedTo(Currency resultCurrency, FxRateProvider rateProvider); CurrencyAmount total(Currency resultCurrency, FxRateProvider rateProvider); MultiCurrencyAmount total(); CurrencyParameterSensitivities diagonal(); CrossGammaParameterSensitivities multipliedBy(double factor); CrossGammaParameterSensitivities mapSensitivities(DoubleUnaryOperator operator); boolean equalWithTolerance(CrossGammaParameterSensitivities other, double tolerance); static CrossGammaParameterSensitivities.Meta meta(); @Override CrossGammaParameterSensitivities.Meta metaBean(); ImmutableList<CrossGammaParameterSensitivity> getSensitivities(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void coverage() { coverImmutableBean(CrossGammaParameterSensitivities.empty()); coverImmutableBean(SENSI_1); coverBeanEquals(SENSI_1, SENSI_2); }
