...e ter o código para os testes como antes.

## Testando: exemplo estendido { #testing-extended-example }

Agora vamos estender este exemplo e adicionar mais detalhes para ver como testar diferentes partes.

### Arquivo de aplicação **FastAPI** estendido { #extended-fastapi-app-file }

Например, вы можете объявить ответ со статус-кодом `404`, который использует Pydantic-модель и имеет пользовательское `description`.

А также ответ со статус-кодом `200`, который использует ваш `response_model`, но включает пользовательский `example`:

{* ../../docs_src/additional_responses/tutorial003_py39.py hl[20:31] *}

Всё это будет объединено и включено в ваш OpenAPI и отображено в документации API:

 * **Be considerate**: People use our work, and we depend on the work of others. Consider users and
   colleagues before taking action. For example, changes to code, infrastructure, policy, and
   documentation may negatively impact others.

 * **Be respectful**: We expect people to work together to resolve conflict, assume good intentions,

    #  The package of SQL file for outsideSql.
    #  This is basically for narrowing SQL-searching target,
    #  for example, when the project has SQL files for other framework.
    #  So basically you don't need this.

    #  You can use variable '$$PACKAGE_BASE$$' that means 'packageBase'.

By using all the previous alternatives I had the chance to learn from all of them, take ideas, and combine them in the best way I could find for myself and the teams of developers I have worked with.

For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

 * annotated by {@link TestSubtype}.
 *
 * <p>These declaration methods rely on Java static type checking to make sure what we want to
 * assert as subtypes are really subtypes according to javac. For example:
 *
 * {@snippet :
 * class MySubtypeTests extends SubtypeTester {
 *   @TestSubtype(suppressGetSubtype = true, suppressGetSupertype = true)
 *   public <T> Iterable<? extends T> listIsSubtypeOfIterable(List<T> list) {

 * <p><b>Warning:</b> The methods of {@code ForwardingSortedSet} forward <i>indiscriminately</i> to
