Python selenium实现断言3种方法解析

1.if ...else ...判断进行断言

from time import *
from selenium import webdriver
def login(user="admin",pwd="123456"):
  driver = webdriver.Chrome()
  driver.implicitly_wait(10)
  driver.get("http://192.168.1.110:8080/cms")
  driver.maximize_window()
  sleep(1)
  driver.find_element_by_id("userAccount").send_keys(user)
  sleep(1)
  driver.find_element_by_id("loginPwd").send_keys(pwd)
  sleep(1)
  driver.find_element_by_id("loginBtn").click()  #登录
  sleep(1)
  users = driver.find_element_by_class_name("c-white").text  #获取用户名
  sleep(1)
  driver.quit()
  if users[6:] == user:
    pass
  else:
    raise AssertionError

if __name__ == '__main__':
  login()

from time import *
from selenium import webdriver
def login(user="admin",pwd="123456"):
  driver = webdriver.Chrome()
  driver.implicitly_wait(10)
  driver.get("http://192.168.1.110:8080/cms")
  driver.maximize_window()
  sleep(1)
  driver.find_element_by_id("userAccount").send_keys(user)
  sleep(1)
  driver.find_element_by_id("loginPwd").send_keys(pwd)
  sleep(1)
  driver.find_element_by_id("loginBtn").click()  #登录
  sleep(1)
  users = driver.find_element_by_class_name("c-white").text  #获取用户名
  sleep(1)
  driver.quit()
  if users[6:7] == user:
    pass
  else:
    assert False

if __name__ == '__main__':
  login()

2.try ... except ...断言

from time import *
from selenium import webdriver
def fatie(title,body):
  dr = login()
  sleep(2)
  dr.find_element_by_partial_link_text("版块").click()
  sleep(1)
  dr.find_element_by_id("subject").send_keys(title)
  sleep(1)
  dr.find_element_by_id("fastpostmessage").send_keys(body)
  sleep(2)
  dr.find_element_by_name("topicsubmit").click()
  sleep(2)
  try:
    dr.find_element_by_id("thread_subject")
  except:
    raise AssertionError
  else:
    pass
  sleep(3)
  dr.quit()

3.assert断言（基于unittest）

• assertIn(arg1, arg2, msg=None)　　 验证 arg1 是 arg2 的子串，不是则 fail
• assertNotIn(arg1, arg2, msg=None) 　　验证 arg1 不是 arg2 的子串，是则 fail
• assertEqual(arg1, arg2, msg=None) 　　验证 arg1=arg2，不等则 fail
• assertNotEqual(arg1, arg2, msg=None)　　 验证 arg1 != arg2, 相等则 fail

import time
import unittest

class Test(unittest.TestCase):
  def test01(self):
    self.assertEqual(2,2,msg="test01 error!")

  def test02(self):
    self.assertNotEqual(1,2,msg="test02 error!")

  def test03(self):
    self.assertIn("fang","xinfangshuo",msg="test03 error!")

  def test04(self):
    self.assertNotIn("xing","xinfangshuo",msg="test04 error!")

  def tearDown(self):
    time.sleep(1)

if __name__ == '__main__':
  unittest.main()
