关于python UI Selenium自动化的一个浏览器driver重复调用问题

最开始也是和大多数一样先写个方法去定义一个驱动每次都要传入一个driver对象

class PageObject(object):
def __init__(self, driver):
self.driver = driver

def test(self):
ele = self.driver.find_element_by_id("menu-user")
return ele

def login(self):
self.driver.find_element_by_id("userAccount").send_keys("admin")
self.driver.find_element_by_id("loginPwd").send_keys(123456)
time.sleep(2)
self.driver.find_element_by_id("loginBtn").click()

from selenium import webdriver
import unittest

class Test(unittest.TestCase):

    def setUp(self):
        self.driver=webdriver.Chrome()
        print("打开浏览器")
        self.driver.get("http://www.baidu.com")
        print(self.driver.current_url)
    def tearDown(self):
        self.driver.close()
        print("close浏览器")
    def test_1(self):
        self.driver.get("http://www.vip.com")
        print(self.driver.current_url)
if __name__ == "__main__":
    unittest.main()

class Test(unittest.TestCase):

@classmethod
def setUpClass(cls):
cls.driver = webdriver.Chrome()
cls.driver.implicitly_wait(5)
cls.driver.maximize_window()
cls.name = "zhangsan"
cls.url="http://192.168.229.128:8080/cms/manage/login.do"
cls.driver.get(cls.url)
# PageObject(cls.driver).login()
print" i am class method ,do i before all method start"

@classmethod
def tearDownClass(cls):
sleep(5)
cls.driver.close()
print "i am class method ,do i after all method finished"

def test1_login(self):
u"用户登录"
PageObject(self.driver).login()

def test2_action(self):
u"用户点击"
PageObject(self.driver).test().click()
print "success"
---------------------

写着就发现太冗余了：换了个思路开始从原始控制驱动driver的产生：

from  selenium import webdriver
from selenium.webdriver.common.by import By

class Driver(object):
        @staticmethod
        def getDriver(option):

            if option=="gc":
                driver=webdriver.Chrome()
            elif option=="ff":
                driver=webdriver.Firefox()
            elif option=="ie":
                driver=webdriver.Ie()
            else:
                raise NameError("目前暂时只支持三剑客浏览器,option desc ==> gc:Chrome,ff:Firefox,ie:IE")
            driver.implicitly_wait(time_to_wait=20)
            driver.maximize_window()
            return driver



class EleUtil(Driver):

    driver=Driver.getDriver("gc")

    @staticmethod
    def find_element(*loc):
        return EleUtil.driver.find_element(*loc)
    @staticmethod
    def find_elements(*loc):
        return EleUtil.driver.find_element(*loc)

class Base(EleUtil):
    @staticmethod
    def openPage(url):
        return EleUtil.driver.get(url)
    @staticmethod
    def getTitle():
        return EleUtil.driver.current_url

import unittest
from lib.selenium_utils import *
from selenium import webdriver
from time import sleep


class Test(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        print("打开浏览器")
        Base.openPage("http://www.baidu.com")
    @classmethod
    def tearDownClass(cls):
        Base.driver.quit()
        print("关闭浏览器")

    # def setUp(self):
    #     print("打开浏览器")
    #     Base().openPage("http://www.baidu.com")
    #     self.driver=Base.driver
    # def tearDown(self):
    #     self.driver.close()
    #     print("关闭浏览器")
    # tip:python 测试用例必须以test开头
    def test_method1(self):
        Base.find_element(By.ID,"kw").send_keys("selenium2 python")
        Base.find_element(By.ID,"su").click()
        print(Base.getTitle())
        sleep(2)
    def test_method2(self):
        Base.openPage("http://www.taobao.com")
        sleep(3)
        print(Base().getTitle())
if __name__ == "__main__":
    unittest.main()  #程序入口

结果还算差强人意速度很快，但是只是在setUpClass模式，一旦切换setUp模式我就会遇到

setUpClass模式

好在思考更好的优化。。。。。待续。。。。
