### Question:
ConfigurationRequirementDefaultValue extends ConfigurationRequirement<S> { @XmlTransient public final void checkAndSetDefaultValues(T... values) throws AlgorithmConfigurationException { try { checkNumberOfSettings(values.length); } catch (AlgorithmConfigurationException e) { throw new AlgorithmConfigurationException( "The number of default values does not match the number of settings."); } this.defaultValues = values; applyDefaultValues(); } ConfigurationRequirementDefaultValue();  ConfigurationRequirementDefaultValue(String identifier);  ConfigurationRequirementDefaultValue(String identifier, int numberOfSettings);  ConfigurationRequirementDefaultValue(String identifier, int minNumberOfSetting,
                                              int maxNumberOfSetting); @XmlTransient final void checkAndSetDefaultValues(T... values); @XmlTransient T getDefaultValue(int index); @XmlTransient void applyDefaultValues(); T[] getDefaultValues(); void setDefaultValues(T[] defaultValues); @Override S[] getSettings(); @Override final void setSettings(S... settings); public T[] defaultValues; }### Answer:
@Test(expected = AlgorithmConfigurationException.class) public void testCheckAndSetDefaultValuesException() throws AlgorithmConfigurationException { ConfigurationRequirementString specificationString = new ConfigurationRequirementString("parameter1", 2); ConfigurationSettingString expectedSetting1 = new ConfigurationSettingString(); ConfigurationSettingString expectedSetting2 = new ConfigurationSettingString(); specificationString.checkAndSetSettings(expectedSetting1, expectedSetting2); specificationString.checkAndSetDefaultValues("test"); }
