### Question:
DynamoDbUtil { public static ParameterizedTypeName item() { return ParameterizedTypeName.get(ClassName.get(Map.class), TypeName.get(String.class), attributeValue()); }  static ClassName attributeValue(); static ParameterizedTypeName item(); static ClassName amazonDynamoDb(); static ClassName getItemRequest(); static ClassName getItemResult(); static ClassName queryRequest(); static ClassName queryResult(); static ClassName scanRequest(); static ClassName scanResult(); static ClassName createTableRequest(); static ClassName scalarAttributeType(); static ClassName keySchemaElement(); static ClassName keyType(); static ClassName attributeDefinition(); static ClassName provisionedThroughput(); static ClassName projection(); static ClassName projectionType(); static ClassName localSecondaryIndex(); static ClassName globalSecondaryIndex();  }### Answer:
@Test void item_onlyUseCase_returnsMapOfStringToAttributeValue() { ParameterizedTypeName item = DynamoDbUtil.item(); assertThat(item).isEqualTo(ParameterizedTypeName.get(ClassName.get(Map.class), TypeName.get(String.class), TypeName.get(AttributeValue.class))); }
