selenium unittest中框架报错

Question

```from selenium import webdriver
from selenium.webdriver.support.select import Select
from time import sleep
import unittest

driver=None

class Webtours(unittest.TestCase):

@classmethod
def setUpClass(cls):
    global driver
    driver=webdriver.Ie()
@classmethod
def tearDownClass(cls):
    driver.quit()
def testOpenWeb(self):
    driver.get("http://localhost:1080/webtours")
    sleep(3)
def testLogin(self):
    sleep(3)
    driver.switch_to.default_content()
    driver.switch_to.frame("body")
    driver.switch_to.frame("navbar")
    driver.find_element_by_name("username").send_keys("zhangsan1")
    driver.find_element_by_name("password").send_keys("1")
    driver.find_element_by_name("login").click()
    sleep(3)

报错如下
During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\admin\Desktop\WebTours.py", line 21, in testLogin
    driver.switch_to.frame("body")
  File "E:\Python\Python36-32\lib\site-packages\selenium\webdriver\remote\switch_to.py", line 87, in frame
    raise NoSuchFrameException(frame_reference)
