```json
{"message": "Hello World"}
```

...this response will return:

```json
{
  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

## Default response class

When creating a **FastAPI** class instance or an `APIRouter` you can specify which response class to use by default.

        try {
          runnable.run()
        } catch (e: Exception) {
          exceptions.add(e)
        }
      }
    }

    fun takeException(): Exception {
      return exceptions.take()
    }
  }

  companion object {
    fun uppercase(original: ResponseBody): ResponseBody {
      return object : ResponseBody() {
        override fun contentType() = original.contentType()

          webSocket: WebSocket,
          t: Throwable,
          response: Response?,
        ) {
          throw e
        }
      },
    )
    newWebSocket()
    assertThat(testLogHandler.take()).isEqualTo("INFO: [WS client] onFailure")
  }

  @Test
  fun throwingOnMessageClosesImmediatelyAndFails() {
    webServer.enqueue(
      MockResponse.Builder()
        .webSocketUpgrade(serverListener)
