它是基於 [HTTPX](https://www.python-httpx.org) 打造，而 HTTPX 的設計又參考了 Requests，所以用起來非常熟悉、直覺。

借助它，你可以直接用 [pytest](https://docs.pytest.org/) 來測試 **FastAPI**。

## 使用 `TestClient` { #using-testclient }

/// info

要使用 `TestClient`，請先安裝 [`httpx`](https://www.python-httpx.org)。

請先建立並啟用一個[虛擬環境](../virtual-environments.md)，然後安裝，例如：

```console
$ pip install httpx
```

///

匯入 `TestClient`。

它基于 [HTTPX](https://www.python-httpx.org)，而HTTPX又是基于Requests设计的，所以很相似且易懂。

有了它，你可以直接与**FastAPI**一起使用 [pytest](https://docs.pytest.org/)。

## 使用 `TestClient` { #using-testclient }

/// info | 信息

要使用 `TestClient`，先要安装 [`httpx`](https://www.python-httpx.org)。

确保你创建并激活一个[虚拟环境](../virtual-environments.md)，然后再安装，例如：

```console
$ pip install httpx
```

///

导入 `TestClient`。

`name="static"`, **FastAPI**'nin dahili olarak kullanabileceği bir isim verir.

Bu parametrelerin hepsi "`static`" ile aynı olmak zorunda değildir; kendi uygulamanızın ihtiyaçlarına ve özel detaylarına göre ayarlayın.

/// info | Информация

OpenAPI 3.1.0 (используется начиная с FastAPI 0.99.0) добавил поддержку `examples`, который является частью стандарта **JSON Schema**.

ResultDictType = Dict[str, Dict[str, Union[str, int]]]

RESULT_STORE_LINK_RE = re.compile(
    r'^INFO: Streaming build results to: (https://[\w./\-]+)')
FAILED_BUILD_LINE = 'FAILED: Build did NOT complete successfully'
BUILD_STATUS_LINE = 'INFO: Build'
TESTS_FAILED_RE = re.compile(r'^INFO: Build completed, \d+ tests? FAILED')

1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
2) If a title is present, prefer these canonical titles:

- `/// note | 참고`
- `/// tip | 팁`
- `/// warning | 경고`
- `/// info | 정보`
- `/// danger | 위험`
- `/// note Technical Details | 기술 세부사항`
- `/// check | 확인`
Notes:

- `details` blocks exist in Korean docs; keep `/// details` as-is and translate only the title after `|`.
