python selenium测试用例生成报告，使用python单例模式

1.测试用例在不同的py文件下，首先看一下我的项目结构，case里放着测试用例，report是存放测试报告，run_main文件为执行用例。用到HTMLTestRunner

2.case里面，如图，t_single是driver，使用的是单例模式

import threading
from selenium import webdriver

class Sin(object):
    _instance_lock=threading.Lock()
    def __init__(self):
        pass
    def __new__(cls, *args, **kwargs):
        if not hasattr(Sin,'_instance'):
            with Sin._instance_lock:
                if not hasattr(Sin, '_instance'):
                    Sin._instance=object.__new__(cls)
                    opt=webdriver.ChromeOptions()
                    opt.add_argument('headless')  #无头模式，可以使用
                    opt.add_argument('disable-infobars')
                    #chrome_options.add_argument('--disable-gpu')
                    cls.driver=webdriver.Chrome() #chrome_options=opt
                    cls.driver.get('https://www.baidu.com')
        return Sin._instance

3.测试用例

 1).test_baidu

from t_single import Sin
import unittest
from selenium import webdriver
from time import sleep

class Ceshi(unittest.TestCase):

    def test_home(self):
        Sin().driver.get('https://www.baidu.com')
        title=Sin().driver.title
        print(title)
        sleep(2)
        self.assertEqual(u'百度一下，你就知道',title)
    def test_search(self):
        sleep(2)
        Sin().driver.get('https://www.baidu.com')
        Sin().driver.find_element_by_id('kw').send_keys('python')
        Sin().driver.find_element_by_id('su').click()
        sleep(2)
        title1=Sin().driver.title
        sleep(2)
        self.assertEqual(u'python_百度搜索',title1)
 2).test_bokeyuan

from selenium import webdriver
from t_single import Sin
import unittest
class Bo(unittest.TestCase):
    def setUp(self):
        print('bokeyuan start...')
    def test_shouye(self):
        Sin().driver.get('https://www.cnblogs.com/')
        title2=Sin().driver.title
        self.assertIn(u'博客园',title2)
    def tearDown(self):
        print('bokeyuan end...')
4.run_main()

#coding: utf - 8
from case.t_single import Sin
from case.test_baidu import Ceshi
from case.test_bokeyuan import Bo
from unittest import TestSuite,TestLoader
import unittest,time,os
import HTMLTestRunner
import smtplib#发送邮件模块
from email.mime.text import MIMEText#定义邮件neir
from email.header import Header#定义邮件标题

def run_main():
    suit = unittest.TestSuite()  #添加测试套件
    suit.addTest(Bo('test_shouye'))
    suit.addTest(Ceshi('test_search'))     #将测试用例添加到测试套件里
    suit.addTest(Ceshi('test_home'))
    file=r'report/report.html'  #测试报告
    fb=open(file,'wb')
    runner = HTMLTestRunner.HTMLTestRunner(stream=fb,title='test_report',description='detail') 
    runner.run(suit)
    fb.close()

if __name__ == '__main__':
    run_main()
