## JSON Lines { #json-lines }

このような場合、1 行に 1 つの JSON オブジェクトを送る「**JSON Lines**」形式を使うのが一般的です。

        controller.setDelayMillisForWaitingNewUrl(0L); // Set to 0 to avoid actual delay

        // This should not throw any exceptions even if helpers are not available
        try {

            // The improved error handling should catch and log any exceptions
            // without propagating them

## NOTE

- Empty delete markers (such as for objects with no other successor versions) do not transition to the new pool to avoid creating empty metadata on the other pool(s). If you believe transitioning empty delete markers is required, open a GitHub issue.

#   TF_BISECT_SCRIPT: The build script path relative to the TF root dir, e.g.
#     ci/official/wheel.sh
#   TFCI: The env config path, relative to the TF root dir, e.g.
#     ci/official/envs/an_env_config

# Note that you can combine bisect.sh with any.sh to bisect a single test:

#   export TF_BISECT_BAD=a_failing_commit_sha

이렇게 호출한 결과는 파이썬 표준인 [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)로 인코딩할 수 있습니다.

JSON 형식(문자열)의 데이터가 들어있는 큰 `str`을 반환하지 않습니다. JSON과 모두 호환되는 값과 하위 값이 있는 파이썬 표준 데이터 구조(예: `dict`)를 반환합니다.

/// note | 참고

`jsonable_encoder`는 실제로 **FastAPI**에서 내부적으로 데이터를 변환하는 데 사용하지만, 다른 많은 시나리오에서도 유용합니다.

In most setups this will keep the scanner slow enough to not impact overall system performance. Setting the `delay` key to a *lower* value will make the scanner faster and setting it to 0 will make the scanner run at full speed (not recommended in production). Setting it to a higher value will make the scanner slower, consuming less resources with the trade off of not collecting metrics for operations like healing and disk usage as fast.

## In Detail { #in-detail }

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip

Note that the test function is now `async def` instead of just `def` as before when using the `TestClient`.

///

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.
