TestCase' object has no attribute 'driver

学习selenium时，运行一直提示‘TestCase' object has no attribute 'driver'

from selenium import webdriver
from time import sleep
import unittest

#driver = webdriver.Chrome

class TestCase(object):
    def __int__(self):
        self.driver =webdriver.Chrome()

    def test(self):
        self.driver.get('http://www.baidu.com')
        sleep(2)
        self.driver.find_element_by_id('kw').send_keys('selenium')
        sleep(2)
        self.driver.find_element_by_id('su').click()

'''''
def test():
    import subprocess
    p =subprocess.Popen("chromedriver")
    p.communicate()
'''''
if __name__ == '__main__':
    case = TestCase()
    case.test()

报错具体信息如下

Traceback (most recent call last):
  File "D:\pythonProject\venv\Scripts\day6\demo1.py", line 26, in <module>
    case.test()
  File "D:\pythonProject\venv\Scripts\day6\demo1.py", line 12, in test
    self.driver.get('http://www.baidu.com')
    ^^^^^^^^^^^
AttributeError: 'TestCse' object has no attribute 'driver'

__int__改为__init__
