## Можливості Pydantic

**FastAPI** повністю сумісний із (та побудований на основі) <a href="https://docs.pydantic.dev/" class="external-link" target="_blank"><strong>Pydantic</strong></a>. Тому будь-який додатковий код Pydantic, який ви маєте, також працюватиме.

<a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> がベースなので、非常に使いやすく直感的です。

これを使用すると、**FastAPI** と共に <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> を直接利用できます。

## `TestClient` を使用

`TestClient` をインポートします。

`TestClient` を作成し、**FastAPI** に渡します。

`test_` から始まる名前の関数を作成します (これは `pytest` の標準的なコンベンションです)。

MinIO places new objects in server pools based on proportionate free space, per pool. Following pseudo code demonstrates this behavior.

```go
func getAvailablePoolIdx(ctx context.Context) int {

        if (fessConfig.isUseOwnTmpDir() && StringUtil.isNotBlank(tmpDir)) {
            ownTmpDir = new File(tmpDir, "fessTmpDir_" + sessionId);
            if (ownTmpDir.mkdirs()) {
                cmdList.add("-Djava.io.tmpdir=" + ownTmpDir.getAbsolutePath());
                cmdList.add("-Dpdfbox.fontcache=" + ownTmpDir.getAbsolutePath());
            } else {
                ownTmpDir = null;
