## Araştırma

Önceki alternatifleri kullanarak hepsinden bir şeyler öğrenip, fikirler alıp, bunları kendim ve çalıştığım geliştirici ekipler için en iyi şekilde birleştirebilme şansım oldu.

Mesela, ideal olarak standart Python tip belirteçlerine dayanması gerektiği açıktı.

/// tip

👉 👷, 👆 💪 `pip install python-dotenv`.

If you are using **Git** (you should), add a `.gitignore` file to exclude everything in your `.venv` from Git.

If you used <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a> to create the virtual environment, it already did this for you, you can skip this step. 😎

///

/// tip

Do this **once**, right after you create the virtual environment.

/// tip | Tipp

Das Wichtige und „Magische“ hier ist, dass `get_current_user` für jede *Pfadoperation* eine andere Liste von `scopes` hat, die überprüft werden.

```console
$ uv venv
```

</div>

/// tip

預設情況下，`uv` 會在一個名為 `.venv` 的目錄中建立一個虛擬環境。

但你可以透過傳遞一個額外的引數來自訂它，指定目錄的名稱。

///

////

這個命令會在一個名為 `.venv` 的目錄中建立一個新的虛擬環境。

/// details | `.venv`，或是其他名稱

你可以在不同的目錄下建立虛擬環境，但通常我們會把它命名為 `.venv`。

///

## 啟動虛擬環境

啟動新的虛擬環境來確保你運行的任何 Python 指令或安裝的套件都能使用到它。

/// tip

**每次**開始一個**新的終端會話**來在這個專案工作時，你都需要執行這個操作。

## In Detail { #in-detail }

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

{* ../../docs_src/async_tests/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`.
