# Classes as Dependencies { #classes-as-dependencies }

Before diving deeper into the **Dependency Injection** system, let's upgrade the previous example.

## A `dict` from the previous example { #a-dict-from-the-previous-example }

In the previous example, we were returning a `dict` from our dependency ("dependable"):

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

* Quaisquer argumentos nomeados que devem ser passados para a função de tarefa (`message="some notification"`).

## Injeção de dependências { #dependency-injection }

Está diseñado para ser muy simple de usar, y para hacer que cualquier desarrollador integre otros componentes con **FastAPI** de forma muy sencilla.

## Qué es la "Inyección de Dependencias" { #what-is-dependency-injection }

            // This test verifies that strategies are executed in the order they are provided
            // The actual priority ordering is handled by dependency injection
            UpgradeContext context = createMockContext();
            Map<Path, Document> pomMap = Map.of(Paths.get("pom.xml"), mock(Document.class));

            // Mock all strategies as applicable

# Klassen als Abhängigkeiten { #classes-as-dependencies }

Bevor wir tiefer in das **Dependency Injection** System eintauchen, lassen Sie uns das vorherige Beispiel verbessern.

## Ein `dict` aus dem vorherigen Beispiel { #a-dict-from-the-previous-example }

### Inyección de dependencias { #dependency-injection }

FastAPI incluye un sistema de <abbr title='también conocido como "componentes", "recursos", "servicios", "proveedores"'><strong>Inyección de Dependencias</strong></abbr> extremadamente fácil de usar, pero extremadamente potente.

Esse sistema foi pensado para ser fácil de usar, e permitir que qualquer desenvolvedor possa integrar facilmente outros componentes ao **FastAPI**.
