## Testing

### Test Framework

JUnit 4 with opensearch-runner (embedded instance)

### Standard Test Setup

        when(transport.getServerEncryptionKey()).thenReturn(key);
        assertArrayEquals(key, transport.getServerEncryptionKey());
        verify(transport).getServerEncryptionKey();

        // Empty array
        byte[] empty = new byte[0];
        when(transport.getServerEncryptionKey()).thenReturn(empty);
        assertArrayEquals(empty, transport.getServerEncryptionKey());

        // Null

請注意，`Offer` 具有一個 `Item` 的列表，而每個 `Item` 又有一個可選的 `Image` 列表。

///

## 純列表的本文 { #bodies-of-pure-lists }

如果你期望的 JSON 本文頂層值是一個 JSON `array`（Python 的 `list`），可以像在 Pydantic 模型中那樣，直接在函式參數上宣告其型別：

```Python
images: list[Image]
```

如下所示：
