        byte[] data = "Hello World".getBytes();

        // When
        outputStream.write(data, 6, 5); // Write "World"

        // Then
        verify(mockTreeHandle, atLeastOnce()).send(any(Smb2WriteRequest.class), any());
    }

    @Test

    PrintWriter w = new PrintWriter(Files.newWriter(temp, UTF_8));
    w.println("hello");
    w.println("");
    w.println(" world  ");
    w.println("");
    w.close();

    assertEquals("hello", Files.readFirstLine(temp, UTF_8));
    assertEquals(ImmutableList.of("hello", "", " world  ", ""), Files.readLines(temp, UTF_8));

    assertTrue(temp.delete());
  }

例えば、以下のような`main.py`ファイルを用意します:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> の第2引数は、デフォルトで返される値を指定します。

この引数を省略するとデフォルト値として`None`が返されますが、ここではデフォルト値として`"World"`を指定しています。

次に、このPythonプログラムを呼び出します。
