Você provavelmente quer testar o provedor externo uma vez, mas não necessariamente chamá-lo em todos os testes que executarem.

Neste caso, você pode sobrepor (*override*) a dependência que chama o provedor, e utilizar uma dependência customizada que retorna um *mock* do usuário, apenas para os seus testes.

### Utilize o atributo `app.dependency_overrides`
