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

/// info

`TestClient` を使用するには、まず [`httpx`](https://www.python-httpx.org) をインストールします。

[仮想環境](../virtual-environments.md) を作成し、それを有効化してから、例えば以下のようにインストールしてください:

```console
$ pip install httpx
```

## Installer les dépendances { #install-dependencies }

Vous devez créer un [environnement virtuel](../virtual-environments.md), l'activer, puis installer `jinja2` :

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Utiliser `Jinja2Templates` { #using-jinja2templates }

## 1. Prerequisites

* Familiarity with [Docker Compose](https://docs.docker.com/compose/overview/).

     * Only under Windows (or hypothetically when running with some other non-POSIX, ACL-based
     * filesystem) does our prod code look up the username. Thus, this test doesn't necessarily test
     * anything interesting under most environments. Still, we can run it (except for Android, at
     * least old versions), so we mostly do. This is useful because we don't actually run our CI on
     * Windows under Java 8, at least as of this writing.
