### Question:
FieldValueModel extends AlertSerializableModel { public void setIsSet(boolean isSet) { this.isSet = isSet; } private  FieldValueModel();  FieldValueModel(Collection<String> values, boolean isSet); Collection<String> getValues(); void setValues(Collection<String> values); @JsonIgnore Optional<String> getValue(); @JsonIgnore void setValue(String value); boolean getIsSet(); void setIsSet(boolean isSet); boolean hasValues(); boolean containsNoData();  }### Answer:
@Test public void setIsSetTest() { FieldValueModel testFieldValueModel = createEmptyFieldValueModel(); testFieldValueModel.setIsSet(Boolean.FALSE); assertFalse(testFieldValueModel.getIsSet()); }
