Variable Not updating during Unit testing

so I have been writing some unit tests. The issue I keep facing is I have to use the class variable but it doesn't get updated. I have tried using the Setup Method but it makes the test run multiple times. And when I use the SetupClass Method the value doesn't get updated. I have to use the building category id from both add_test in get_test.

Here's the code:

class buildingTest(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls.cookie = login.machine()
        cls.test_name = []
        cls.test_result = []
        cls.procedures_in_tests = []

    def setUp(self) -> None:
        self.building_id_one = self.test_add_1()
        self.building_id_two = self.test_add_2()

    def test_add_1(self):
        entered_data = {
            "area": 1,
            "name": "Testing 1",
            "building_category_id": 1,
            "electricity_model_id": 1,
            "gas_model_id": 1,
            "address_id": 1,
            "built": "test",
            "company_id": 1,
        }
        try:
            building_id = add_building(
                self.cookie,
                entered_data["area"],
                entered_data["name"],
                entered_data["building_category_id"],
                entered_data["electricity_model_id"],
                entered_data["gas_model_id"],
                entered_data["address_id"],
                entered_data["built"],
                entered_data["company_id"],
            )

            time.sleep(0.1)
            building_data = get_building(self.cookie, building_id)

            buiding_category_name = get_building_category_name(
                self.cookie, entered_data["building_category_id"]
            )
            street_address = get_street_address(self.cookie, entered_data["address_id"])

            entered_data.pop("building_category_id")
            entered_data.pop("address_id")
            entered_data.pop("company_id")
            entered_data["building_category_name"] = buiding_category_name
            entered_data["street_address"] = street_address

            for key in entered_data:
                self.assertEqual(
                    entered_data[key], building_data[key], f"{key} should be same"
                )
