<div class="termy">

```console
$ bash scripts/format.sh
```

</div>

It will also auto-sort all your imports.

## Tests

There is a script that you can run locally to test all the code and generate coverage reports in HTML:

<div class="termy">

```console
$ bash scripts/test-cov-html.sh
```

</div>

# About FastAPI versions { #about-fastapi-versions }

**FastAPI** is already being used in production in many applications and systems. And the test coverage is kept at 100%. But its development is still moving quickly.

New features are added frequently, bugs are fixed regularly, and the code is still continuously improving.

* **WebSocket** 지원.
* 프로세스 내 백그라운드 작업.
* 시작 및 종료 이벤트.
* HTTPX 기반 테스트 클라이언트.
* **CORS**, GZip, 정적 파일, 스트리밍 응답.
* **세션과 쿠키** 지원.
* 100% test coverage.
* 100% type annotated codebase.

## Pydantic 기능 { #pydantic-features }

**FastAPI**는 [**Pydantic**](https://docs.pydantic.dev/)과 완벽하게 호환되며(또한 이를 기반으로 합니다). 따라서 추가로 가지고 있는 Pydantic 코드도 모두 동작합니다.

/**
 * Tests for StaticJAASConfiguration.

 * Coverage goals:
 * - Happy path with default and custom options.
 * - Null/empty/ignored name parameter handling.
 * - Null options edge case.
 * - Repeated calls equivalence and instance separation.
