Python+Selenium. Как правильно сделать инициализацию объектов страниц?

Вопрос следующий:

имеется тест:


import time
import unittest

from ddt import ddt, data, unpack

from base.baseclass import BaseClass
from base.selenium_driver import SeleniumDriver
from pages.home_page import HomePage
from pages.login_page import LoginPage
from pages.notebook_page import NotebookPage


@ddt
class TestLogin(unittest.TestCase):

    @data(('chrome', '59.0'), ('chrome', '67.0'), ('firefox', '57.0'), ('firefox', '60.0'))
    @unpack
    def test_valid_login_(self, browser, version):
        # creating instance of Base class
        self.bc = BaseClass()
        # opening browser
        self.driver = self.bc.open_browser_remote(browser, version)
        # creating instance of Selenium Driver class
        self.sw = SeleniumDriver(self.driver)
        # creating instance of Login page
        self.lp = LoginPage(self.driver)
        # creating instance of Home page
        self.hp = HomePage(self.driver)
        # creating instance of Notebook page
        self.np = NotebookPage(self.driver)
        # opening website in browser
        self.bc.open_go()
        # signing in with credentials specified in config.ini file
        self.lp.login(self.bc.get_username(), self.bc.get_password())
        # verifying that sign in was successful and we are now located on the Home page
        assert self.hp.located_on_homepage() == True
        # getting handle of current window so later we can switch to new one
        parentHandle = self.bc.get_window_handle()
        # clicking on 'New' button
        self.hp.click_new_button()
        # switching to new opened window
        self.bc.switch_to_new_window(parentHandle)
        # click on text field
        self.np.click_text_field()
        # enter text to field in notebook
        self.np.text_to_field("print('Hello')")
        # run notebook
        self.np.run_notebook()
        # assert notebook run
        result = self.np.verify_output()
        assert result == True
        # get name of current notebook so we can delete it later
        notebook_name = self.np.get_name_notebook()
        # click save button
        self.np.click_save_button()
        # switch back to parent window
        self.driver.switch_to_window(parentHandle)
        # refresh page
        self.driver.refresh()
        # click on checkbox of created notebook
        self.hp.click_checkbox(notebook_name)
        # delete notebook
        self.hp.delete_notebook()
        # log out
        self.hp.click_logout_button()
        # verifying that we logged out and that we are now located on Login page
        assert self.lp.located_on_login_page() == True
        # closing browser
        self.driver.quit()

как правильно сделать инициализацию объектов страниц в методе setUp?
Получается так, что если просто перемещу туда:



# creating instance of Base class
        self.bc = BaseClass()
        # opening browser
        self.driver = self.bc.open_browser_remote(browser, version)
        # creating instance of Selenium Driver class
        self.sw = SeleniumDriver(self.driver)
        # creating instance of Login page
        self.lp = LoginPage(self.driver)
        # creating instance of Home page
        self.hp = HomePage(self.driver)
        # creating instance of Notebook page
        self.np = NotebookPage(self.driver)

то метод запустится только один раз, а мне надо тесты провести на разных браузерах…
