如何使用Python selenium实现断言的三种方法进行长尾词改写？

本文共计503个文字，预计阅读时间需要3分钟。

pythonif ... else 结构用于判断执行不同的代码块。下面是简化后的代码内容：

pythonfrom 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()

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("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("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()
