Selenium liveServerTestCase is using Test Database instead of Project database (Django)

Question

I am beginning to try Django testing using selenium , I am following this tutorial Selenium | Django | Gentle Introduction, Setup and Start Testing

while trying to run a simple login test case i am getting in the test browser:

username and password do not match

i think it is because the test case is not getting access to project database and instead is using test database.Can someone also guide me regarding whether the LiveServerTestCase uses Project Database or separate Test Database.

for login i am using authentication utility provided by django.contrib.auth.urls

test.py

from django.test import LiveServerTestCase
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time


class LoginFormTest(LiveServerTestCase):

    def testform(self):
        driver = webdriver.Chrome(executable_path="/Users/mueezkhan/django-test/chromedriver")

        driver.get(self.live_server_url + '/accounts/login/')
        time.sleep(3)
        user_name = driver.find_element_by_name('username')
        user_password = driver.find_element_by_name('password')
        time.sleep(3)
        submit = driver.find_element_by_id('submit')

        

        
        user_name.send_keys('admin')
        user_password.send_keys('admin')

        submit.send_keys(Keys.RETURN)
        assert 'admin' in driver.page_source
