함수의 첫 번째 부분, 즉 `yield` 이전의 코드는 애플리케이션이 시작되기 **전에** 실행됩니다.

그리고 `yield` 이후의 부분은 애플리케이션이 완료된 후 **나중에** 실행됩니다.

이것은 함수를 "**비동기 컨텍스트 매니저**"라고 불리는 것으로 변환시킵니다.

# Testing Events: startup - shutdown

Cuando necesitas que tus manejadores de eventos (`startup` y `shutdown`) se ejecuten en tus tests, puedes usar el `TestClient` con un statement `with`:

	return nil

// key options
type options struct {
	ttl int64 // expiry in seconds
