applications ClassRealm as the parent but the search order would be child first, and the parent ClassRealm can optionally choose to limit the searching to particular classes. The application ClassRealm, or parent ClassRealm, should only expose the API in the form of and application interface and model classes that may be required by plugins.

For debugging purposes we also need to keep track of what versions of artifacts are being used so that when we are debugging in the IDE we can find the specific...

### Pydantic v1 parameters { #pydantic-v1-parameters }

If you need to use some of the FastAPI-specific tools for parameters like `Body`, `Query`, `Form`, etc. with Pydantic v1 models, you can import them from `fastapi.temp_pydantic_v1_params` while you finish the migration to Pydantic v2:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

Importe `TestClient`.

Crie um `TestClient` passando sua aplicação **FastAPI** para ele.

Crie funções com um nome que comece com `test_` (essa é a convenção padrão do `pytest`).

Use o objeto `TestClient` da mesma forma que você faz com `httpx`.

Escreva instruções `assert` simples com as expressões Python padrão que você precisa verificar (novamente, `pytest` padrão).

{* ../../docs_src/app_testing/tutorial001_py39.py hl[2,12,15:18] *}

    assertThat(body.value(1)).isEqualTo("final frontier")
    assertThat(body.value(2)).isEqualTo("%25")
    assertThat(body.contentType().toString()).isEqualTo(
      "application/x-www-form-urlencoded",
    )
    val expected = "a%2B%3D%26+b=c%2B%3D%26+d&space%2C+the=final+frontier&%2525=%2525"
    assertThat(body.contentLength()).isEqualTo(expected.length.toLong())
    val out = Buffer()
    body.writeTo(out)

Por ejemplo:

* Para pasar un parámetro de *path* o *query*, añádelo a la URL misma.
* Para pasar un cuerpo JSON, pasa un objeto de Python (por ejemplo, un `dict`) al parámetro `json`.
* Si necesitas enviar *Form Data* en lugar de JSON, usa el parámetro `data` en su lugar.
* Para pasar *headers*, usa un `dict` en el parámetro `headers`.
* Para *cookies*, un `dict` en el parámetro `cookies`.

    private void readObject(ObjectInputStream stream) throws InvalidObjectException {
    throw new InvalidObjectException("Use SerializedForm");
  }

  /** Serialized form of the map, to avoid serializing the constraint. */
  private static final class SerializedForm<B extends @Nullable Object> implements Serializable {
    private final Map<Class<? extends @NonNull B>, B> backingMap;

E.g.:

* To pass a *path* or *query* parameter, add it to the URL itself.
* To pass a JSON body, pass a Python object (e.g. a `dict`) to the parameter `json`.
* If you need to send *Form Data* instead of JSON, use the `data` parameter instead.
* To pass *headers*, use a `dict` in the `headers` parameter.
* For *cookies*, a `dict` in the `cookies` parameter.

Наприклад:

* Щоб передати *path* або *query* параметр, додайте його безпосередньо до URL.
* Щоб передати тіло JSON, передайте Python-об'єкт (наприклад, `dict`) у параметр `json`.
* Якщо потрібно надіслати *Form Data* замість JSON, використовуйте параметр `data`.
* Щоб передати заголовки *headers*, використовуйте `dict` у параметрі `headers`.
* Для *cookies* використовуйте `dict` у параметрі `cookies`.
