### Question:
VocabConcept extends HypermediaEnabledData { public VocabConcept attributes(final List<VocabConceptAttribute> attributes) { this.setAttributes(attributes); return this; }  String getDescription(); void setDescription(final String description); VocabConcept description(final String description); String getNote(); void setNote(final String note); VocabConcept note(final String note); URI getGedcomxUri(); void setGedcomxUri(final URI gedcomxUri); VocabConcept gedcomxUri(final URI gedcomxUri); List<VocabTerm> getVocabTerms(); void setVocabTerms(final List<VocabTerm> vocabTerms); void addVocabTerm(VocabTerm vocabTerm); VocabConcept vocabTerms(final List<VocabTerm> vocabTerms); List<VocabConceptAttribute> getAttributes(); void setAttributes(final List<VocabConceptAttribute> attributes); VocabConcept attributes(final List<VocabConceptAttribute> attributes); void accept(FamilySearchPlatformModelVisitor visitor); void embed(VocabConcept vocabConcept);  }### Answer:
@Test public void testAttributes() { final VocabConceptAttribute testVocabConceptAttribute = new VocabConceptAttribute() .id("testId") .name("testName") .value("testValue"); List<VocabConceptAttribute> testVocabConceptAttributes = Collections.singletonList(testVocabConceptAttribute); VocabConcept classUnderTest = new VocabConcept(); classUnderTest.setAttributes(testVocabConceptAttributes); assertEquals(classUnderTest.getAttributes(), testVocabConceptAttributes); classUnderTest = new VocabConcept().attributes(testVocabConceptAttributes); assertEquals(classUnderTest.getAttributes(), testVocabConceptAttributes); }
