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()
