### Question:
Stage { public TypeElement getDocumentElement() { return schema.getDocumentElement(); }  Stage withIndex(DynamoIndex index, KeyLengthType keyLengthType); Stage addWither(StageTypeSpec stage); Stage addUser(StageTypeSpec stage); boolean isStagedBuilder(); List<FieldSpec> getAttributesAsFields(); TypeElement getDocumentElement();  }### Answer:
@Test void getDocumentElement_onlyUseCase_returnsElementFromSchema() { Stage stage = new Stage(schema() .document(DocumentDynamoAttribute.builder() .element(typeElementMock) .build()) .build(), null); assertThat(stage.getDocumentElement()).isEqualTo(typeElementMock); }
