이는 여러분이 다음과 같은 사항을 필요로 할 때 매우 유용합니다:

* 공용된 로직을 가졌을 경우 (같은 코드 로직이 계속 반복되는 경우).
* 데이터베이스 연결을 공유하는 경우.
* 보안, 인증, 역할 요구 사항 등을 강제하는 경우.
* 그리고 많은 다른 사항...

이 모든 사항을 할 때 코드 반복을 최소화합니다.

## 첫번째 단계 { #first-steps }

아주 간단한 예제를 봅시다. 너무 간단할 것이기에 지금 당장은 유용하지 않을 수 있습니다.

하지만 이를 통해 **의존성 주입** 시스템이 어떻게 작동하는지에 중점을 둘 것입니다.

### 의존성 혹은 "디펜더블" 만들기 { #create-a-dependency-or-dependable }

의존성에 집중해 봅시다.

Follow these steps to run the Spark Pi example:

- Login as user **‘spark’**.
- When the job runs, the library can now use **MinIO** during intermediate processing.

        # self._type_adapter.validate_python(value)
        # This uses Pydantic's dump_json() which serializes directly to JSON
        # bytes in one pass (via Rust), avoiding the intermediate Python dict
        # step of dump_python(mode="json") + json.dumps().
        return self._type_adapter.dump_json(
            value,
            include=include,
            exclude=exclude,
            by_alias=by_alias,

  # Find all one-step dependencies of those tests which are from //tensorflow
  # (since external deps will come from Python-level pip dependencies),
  # excluding dependencies and files that are known to be unneccessary.

 * the same structure:
 *
 *  * prepare a set of plans, each with a predictable connect delay
 *  * attempt to find a connection
 *  * step through time, asserting that the expected side effects are performed.
