python selenium测试用例断言

1.if ...else ...判断进行断言

#coding=utf-8
from time import *
from selenium import webdriver
"):
    driver = webdriver.Chrome()
    driver.implicitly_wait(10)
    driver.get("http://192.168.1.222:8881/discuz")
    driver.maximize_window()
    sleep(1)
    driver.find_element_by_id("ls_username").send_keys(user)
    sleep(1)
    driver.find_element_by_id("ls_password").send_keys(pwd)
    sleep(1)
    driver.find_element_by_xpath('//*[@id="lsform"]/div/div/table/tbody/tr[2]/'
                                 'td[3]/button').click()    #登录
    sleep(1)
    users = driver.find_element_by_xpath('//*[@id="um"]/p[1]/strong/a').text    #获取用户名
    if users == user:
        pass
    else:
        raise AssertionError
    return driver

2.try ... except ...断言

#coding=utf-8

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

#coding=utf-8
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)

    unittest.main()
