MockWebServer
=============

A scriptable web server for testing HTTP clients


### Motivation

This library makes it easy to test that your app Does The Right Thing when it
makes HTTP and HTTPS calls. It lets you specify which responses to return and
then verify that requests were made as expected.

Because it exercises your full HTTP stack, you can be confident that you're

테스트해보기:

* 여러 브라우저 탭에서 앱을 엽니다.
* 각 탭에서 메시지를 작성합니다.
* 한 탭을 닫아보세요.

`WebSocketDisconnect` 예외가 발생하며, 다른 모든 클라이언트가 다음과 같은 메시지를 수신합니다:

```
Client #1596980209979 left the chat
```

/// tip | 팁

위 응용 프로그램은 여러 WebSocket 연결에 메시지를 브로드캐스트하는 방법을 보여주는 간단한 예제입니다.

그러나 모든 것을 메모리의 단일 리스트로 처리하므로, 프로세스가 실행 중인 동안만 동작하며 단일 프로세스에서만 작동합니다.

- `outputToken` – A token added to the response headers when the Lambda function returns the transformed object. This is used by MinIO to verify the incoming response validity.

Lets start the lambda handler.
