そして呼び出すと:

```Python
print(user_dict)
```

以下のようなPythonの`dict`を得ることができます:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

#### `dict`の展開

`user_dict`のような`dict`を受け取り、それを`**user_dict`を持つ関数（またはクラス）に渡すと、Pythonはそれを「展開」します。これは`user_dict`のキーと値を直接キー・バリューの引数として渡します。

そこで上述の`user_dict`の続きを以下のように書くと:

```Python

 *      writes to, reads from, and closes the pipe in a single operation.
 * <li> <code>TransactNamedPipe</code> A message-type pipe call that
 *      writes to and reads from an existing pipe descriptor in one operation.
 * <li> <code>CreateFile</code>, <code>ReadFile</code>,
 *      <code>WriteFile</code>, and <code>CloseFile</code> A byte-type pipe can
 *      be opened, written to, read from and closed using the standard Win32

        .isEqualTo("At least one TLS version is required")
    }
  }

  @Test
  fun noCipherSuites() {
    assertFailsWith<IllegalArgumentException> {
      ConnectionSpec
        .Builder(ConnectionSpec.MODERN_TLS)
        .cipherSuites(*arrayOf<CipherSuite>())
        .build()
    }.also { expected ->
      assertThat(expected.message)
        .isEqualTo("At least one cipher suite is required")
    }
  }

        // Assert
        assertNotNull(result, "Unwrapped transport should not be null");
        assertEquals(mockUnwrappedTransport, result, "Returned unwrapped transport should be the mocked one");
        verify(smbTransport).unwrap(SmbTransport.class); // Verify that the method was called
    }

    @Test
    void testClose() throws Exception {
        // Act
        smbTransport.close();
