## Erros das dependências e valores de retorno { #dependencies-errors-and-return-values }

Você pode utilizar as mesmas *funções* de dependências que você usaria normalmente.

### Requisitos de Dependências { #dependency-requirements }

Dependências podem declarar requisitos de requisições (como cabeçalhos) ou outras subdependências:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[8,13] *}

        <include>*.cmd</include>
        <include>*.conf</include>
        <include>*.java</include>
      </includes>
      <lineEnding>dos</lineEnding>
    </fileSet>
    <fileSet>
      <directory>target/dependency/org/jline/nativ</directory>
      <outputDirectory>lib/jline-native</outputDirectory>
      <includes>
        <include>**/*.so</include>
        <include>**/*.jnilib</include>
        <include>**/*.dll</include>

En este caso, puedes sobrescribir la dependencia que llama a ese proveedor y usar una dependencia personalizada que devuelva un usuario de prueba, solo para tus tests.

### Usa el atributo `app.dependency_overrides` { #use-the-app-dependency-overrides-attribute }

Para estos casos, tu aplicación **FastAPI** tiene un atributo `app.dependency_overrides`, es un simple `dict`.

    with pytest.raises((ValueError, Exception)):
        client.get("/broken-session-stream")

    When a dependency with yield raises after the streaming response already started

будет корректной для использования в качестве зависимости **FastAPI**.

На самом деле, FastAPI использует эти два декоратора внутренне.

## Зависимость базы данных с помощью `yield` { #a-database-dependency-with-yield }

Например, с его помощью можно создать сессию работы с базой данных и закрыть её после завершения.

Перед созданием ответа будет выполнен только код до и включая оператор `yield`:
