一、使用装饰器实现单例
def Singleton(cls):_instance = {}def _singleton(*args, **kargs):if cls not in _instance:_instance[cls] = cls(*args, **kargs)return _instance[cls]return _singleton@Singleton
class A(object):a = 1def __init__(self, x=0):self.x = xa1 = A(2)
a2 = A(3)二、web自动化driver实现单例模式
2.1 编写单例模式的装饰器
singleton.py
#coding:utf-8
#单例模式函数，用来修饰类
def singleton(cls,*args,**kw):instances = {}def _singleton():if cls not in instances:instances[cls] = cls(*args,**kw)return instances[cls]return _singleton
2.2 driver 使用装饰器，实现单例模式
GetSeleniumDriver.py
# -*- coding:utf-8 -*-
from selenium import webdriver
from singleton import singleton
@singleton
class GetSeleniumDriver(object):def __init__(self):self.driver = webdriver.Chrome()
2.3 获取driver的实例，就是单例了
class My_task(RES):def __init__(self):self.driver=GetSeleniumDriver().driverdef Making_task_Button(self):Making_task_Button=self.driver.find_element_by_xpath(RES.Making_task_Button_xpth)return Making_task_Buttondef Audit_task_Button(self):Audit_task_Button=self.driver.find_element_by_xpath(RES.Audit_task_Button_xpth)return Audit_task_Button
三、在自动化项目中具体的应用
3.1项目结构
一、工具层 Utils
1 singleton.py 是单例装饰器
#coding:utf-8
#单例模式函数，用来修饰类
def singleton(cls,*args,**kw):instances = {}def _singleton():if cls not in instances:instances[cls] = cls(*args,**kw)return instances[cls]return _singleton
2 GetSeleniumDriver.py driver实现单例
# -*- coding:utf-8 -*-
from selenium import webdriver
from Utils.singleton import singleton
@singleton
class GetSeleniumDriver(object):def __init__(self):self.driver = webdriver.Chrome()
二、页面元素层 TsetSharelab
My_task.py
# -*- coding:utf-8 -*-from Utils.GetSeleniumDriver import GetSeleniumDriverclass My_task():def __init__(self):self.driver=GetSeleniumDriver().driverdef Making_task_Button(self):Making_task_Button=self.driver.find_element_by_xpath('/html/body/div[3]/div[1]/div/a[1]')return Making_task_Buttondef Audit_task_Button(self):Audit_task_Button=self.driver.find_element_by_xpath('/html/body/div[3]/div[1]/div/a[1]')return Audit_task_Button
三、流程层
把一步一步的动作，封装成一个业务流程
BookCity_page_process.py
# -*- coding:utf-8 -*-
from Utils.GetSeleniumDriver import GetSeleniumDriverimport timeclass BookCity_page_process(object):def __init__(self):self.driver=GetSeleniumDriver().driverdef WeiBo_Loain_To_Share(self): time.sleep(3)self.driver.find_elements_by_class_name('W_input').pop(0).send_keys(123)time.sleep(1)self.driver.find_elements_by_class_name('W_input').pop(1).send_keys(456)
四、case层 ，把业务逻辑组成一条条用例
test_case.py
#coding:utf-8
from time import sleep
from Utils.GetSeleniumDriver import GetSeleniumDriverclass CreativeBooks(unittest.TestCase):@classmethoddef setUpClass(self):self.driver = GetSeleniumDriver().driversleep(2)@classmethoddef tearDownClass(self):passdef setUp(self):self.driver = GetSeleniumDriver().driverself.driver.get("http://t.com/")self.driver.maximize_window()sleep(1)Creative_books().Creative_books_Button().click()def tearDown(self):self.driver.delete_all_cookies()def testa(self):#新建图书Creative_books().CreatBook_Button().click()#输入书名Creative_books().Input_book_name().send_keys(u"A1一")#保存书名def testb(self):first = self.driver.current_window_handleCreative_books().Help_center_Button().click()
