unittest 怎么实现一个类中只启动一次浏览器，代码见下图
一个class中有四个case，但是每个case都需要启动一遍浏览器，百度了一下unit test的执行顺序是 setUpclass setUp TearDownTeardownclass，把启动的初始化操作写在setUPclass中后一个报错driver的问题。求解其他方法使用‘@classmethod’支持在一个类中只进行一次初始化和清理，下面是个例子：
#!/user/bin/env python
#encoding: utf-8
import unittest
from selenium import webdriver
class SearchTests(unittest.TestCase):
@classmethod
def setUpClass(cls):
# 基于类的setUp()和tearDown()方法
# 这里的‘@classmethod’支持在一个类中只进行一次初始化和清理
cls.driver = webdriver.Firefox()
cls.driver.implicitly_wait(30)
cls.driver.maximize_window()
# navigate to the application home page
cls.driver.get("http://www.jd.com/")
def test_search_by_category(self):
# get the search textbox
self.search_field = self.driver.find_element_by_id("key")
self.search_field.clear()
self.search_field.send_keys("phones")
#submit
self.search_btn = self.driver.find_element_by_xpath("//button[@clstag='h|keycount|2015|03c']")
self.search_btn.click()
# get all the anchor elements which have product names displayed
# currently on result page using find_elements_by_xpath method
products = self.driver.find_elements_by_xpath("//div[@class='p-img']/a")
self.assertGreater(len(products), 3, "more than 3~~")
def test_search_by_name(self):
# get the search textbox
self.search_field = self.driver.find_element_by_id("key")
self.search_field.clear()
self.search_field.send_keys("android")
#submit
self.search_btn = self.driver.find_element_by_xpath("//button[@clstag='shangpin|keycount|toplist1|b03']")
self.search_btn.click()
# get all the anchor elements which have product names displayed
# currently on result page using find_elements_by_xpath method
products = self.driver.find_elements_by_xpath("//div[@class='p-img']/a")
self.assertGreater(len(products), 4, "more than 4~~")
@classmethod
def tearDownClass(cls):
# close the browser window
cls.driver.quit()
if __name__ == '__main__':
unittest.main(verbosity=2)

使用‘@classmethod’支持在一个类中只进行一次初始化和清理，下面是个例子：
#!/user/bin/env python
#!/usr/bin/env python
#coding:utf-8
from lib2to3.pgen2 import driver
import unittest
from appium.webdriver.common.mobileby import MobileBy
from selenium import webdriver
from Pages import BasePages
from ddt import ddt,data,unpack
from Pages import basetestcase
@ddt
class LoginPage(unittest.TestCase):
@classmethod
def setUpclass(cls):
cls.driver=webdriver.Firefox()
cls.driver.maximize_window()
cls.driver.get('http://bj.58.com')
cls.driver.implicitly_wait(30)
@data(('','',u'您还没有输入账户名'),('','123321',u''),('ljjtest12','',u'您还没有输入密码'))
@unpack
def test_FailLogin(self,value1,value2,expected):
'''验证:错误登陆返回信息'''
BasePages.Login(self.driver,value1,value2)
self.assertEqual(BasePages.getErrorText(self.driver),expected)
def test_successLogin(self,username='ljjtest12',password='123321',):
'''验证:登陆成功'''
BasePages.Login(self.driver,username,password,)
self.assertTrue(MobileBy.ACCESSIBILITY_ID, '退出')
@classmethod
def tearDownClass(cls):
cls.driver.quit()
# def tearDown(self):
# pass
# # self.driver.quit()
if __name__=='__main__':
unittest.main(verbosity=2)
我这个还是报错driver的问题

可以给我看看你调用BasePages.Login这个脚本吗，看提示像是传参过程出错了 若尘_51 发表于 2016-9-23 08:45

看了你的脚本，确实是传参的问题（driver这个参数），我也对传参不熟，试试下面的：
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
import time as t
#等待方法
import self
def wait():
t.sleep(2)
def Login(self,username,password):
wait()
clickLogin(self,username,password)
def clickLogin(self,username,password):
wait()
self.driver.find_element_by_id('login').find_element_by_link_text(u'登录').click()
self.driver.find_element_by_id('login_tab_orig').click()
self.driver.find_element_by_id('username_new').send_keys(username)
self.driver.find_element_by_id('password_new').send_keys(password)
self. driver.find_element_by_id('btnSubmit_new').click()
def getErrorText(self):
wait()
return self.driver.find_element_by_id("tipli_new").text
