python selenium driver实现单例

傲娇的喵酱 人气:0

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 = 1
 
    def __init__(self, x=0):
        self.x = x
 
 
a1 = 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().driver
 
    def Making_task_Button(self):
        Making_task_Button=self.driver.find_element_by_xpath(RES.Making_task_Button_xpth)
        return Making_task_Button
 
    def 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

四、工具层 Utils

4.1singleton.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

4.2 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()

五、页面元素层 TsetSharelab

My_task.py

# -*- coding:utf-8 -*-
 
from Utils.GetSeleniumDriver import GetSeleniumDriver
 
 
class My_task():
    def __init__(self):
        self.driver=GetSeleniumDriver().driver
 
    def 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_Button
 
    def 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

六、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 GetSeleniumDriver
 
import time
 
class BookCity_page_process(object):
    def __init__(self):
        self.driver=GetSeleniumDriver().driver
 
    def 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)

七、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 GetSeleniumDriver
 
class CreativeBooks(unittest.TestCase):
    @classmethod
    def setUpClass(self):
        self.driver = GetSeleniumDriver().driver
        sleep(2)
    @classmethod
    def tearDownClass(self):
        pass
 
    def setUp(self):
        self.driver = GetSeleniumDriver().driver
