            'item1',
            'item2',
        ],
        'to_be_changed' => [
            'item3',
            'item4',
        ]
    ]
];

$actual = [
    'object' => [
        'to_be_added' => [
            'item3',
            'item4',
        ],
        'to_be_changed' => [
            'item5',
