I just tried to compare values between model and serializer

I encountered tests like below. And I want to know why he checked the value through serializer. So, I check the values.

Create board
Add param
Check the param in the board

def test(self):
        board = create_board(user=self.user, title='Sunday Roast secret')
        com = Command.objects.create(user=self.user, content='So interesting')
        board.commands.add(com)

        params = {'commands': f'{com.id}'}
        res = self.client.get(BOARD_URL, params)

        b1 = BoardSerializer(board)
        self.assertIn(b1.data, res.data)

board

Sunday Roast secret

b1

BoardSerializer(<Board: Sunday Roast secret>): 
id = IntegerField(label='ID', read_only=True) 
title = CharField(max_length=255)
tags = TagSerializer(many=True, required=False):
id = IntegerField(label='ID', read_only=True)
name = CharField(max_length=255)
commands = CommandSerializer(...)

Serializer returns all the values stored. If you want to check the value through the data included, you can use this way.
