# Clases como dependencias { #classes-as-dependencies }

Antes de profundizar en el sistema de **Inyección de Dependencias**, vamos a mejorar el ejemplo anterior.

## Un `dict` del ejemplo anterior { #a-dict-from-the-previous-example }

En el ejemplo anterior, estábamos devolviendo un `dict` de nuestra dependencia ("dependable"):

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

    checkNotNull(str);
    return (format == this) ? str : convert(format, str);
  }

  /** Enum values can override for performance reasons. */
  String convert(CaseFormat format, String s) {
    // deal with camel conversion
    StringBuilder out = null;
    int i = 0;
    int j = -1;
    while ((j = wordBoundary.indexIn(s, ++j)) != -1) {
      if (i == 0) {
        // include some extra space for separators

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | İpucu

Test fonksiyonu artık `TestClient` kullanırken eskiden olduğu gibi sadece `def` değil, `async def`.

///

Ardından app ile bir `AsyncClient` oluşturup `await` kullanarak ona async request'ler gönderebiliriz.

        * En requests, se leerá una list, eliminando duplicados y convirtiéndola en un `set`.
        * En responses, el `set` se convertirá en una `list`.
        * El esquema generado especificará que los valores del `set` son únicos (usando `uniqueItems` de JSON Schema).
* `bytes`:
    * `bytes` estándar de Python.
    * En requests y responses se tratará como `str`.

         * unique within a single POM. Upon multiple declarations, 2.x just kept the last one but retained the order of
         * the first occurrence. So when we're in lenient/compat mode, we have to deal with such broken POMs and mimic
         * the way 2.x works. When we're in strict mode, the removal of duplicates just saves other merging steps from
         * aftereffects and bogus error messages.
