selenium+python自动化框架

流程:

 

 

环境准备

eclipse ：需安装pydev、testng插件

python ：安装python完成后，需 pip下安装selenium：命令： pip install selenium

我现在的环境：eclipse【 Neon.3 Release (4.6.3)】+JDK1.8+python3.6.3+pydev 6.4.4+selenium3.8.1

2  eclipse创建python项目

 

1  src：框架主要代码，很重要！！其中，framework主要实现 配置文件的读取，日志类，读取数据库，selenium常用方法封装，浏览器启动类等

2  config ：配置文件，配置url，数据库等

data：放的测试案例的数据—因为表太多，现在不用了，数据改放在了数据库中

3  logs：顾名思义，放生成的日志

4  PageElement：放需要的页面元素

5  report：生成的测试报告会在这里

6  result：本来想放具体的测试结果，如哪条案例未通过放这里！！现在也没啥用！可以不用

7  screenshot：放运行错误后的截图

8  tools：工具类：如驱动啥的

1. 测试数据准备

3.1 测试元素表

3.2测试数据表**

 

1. 测试主框架的搭建

4.1框架目录

 

 

每个包的解释：

 

framework：自动化测试框架的支撑，主要实现功能为对selenium一些常用方法的封装，配置文件的读取、测试数据的读取，浏览器驱动的调用，日志文件的创建等；

【11月更新】现在添加了读取数据库的类

pageobject：采用了页面对象模型Page-Object的思想，将被测系统的每个页面对应成一个页面类，将每个页面对象的唯一属性存放于页面元素表中，并通过该页面类进行读取，实现该页面的操作方法，如：输入，点击等操作

testsuit：测试套件。测试套件是很多测试用例的集合，一个测试套件可以随意管理多个测试用例

testrunner：用来执行加载测试用例，并执行用例，且提供测试输出的一个组件。test runner可以加载test case或者test suite进行执行测试任务。

test：自测用的，可以不要！！！

 

4.2框架之-----浏览器引擎配置 browser-engine类

4.2.1.config下新建：config.ini

#  this is config file, only store browser type and server URL  
  
[browserType]  
browserName = Firefox  
#browserName = Chrome  
#browserName = IE  
  
[testServer]  
URL = http://XXXXXXXXXXXXXXX  #输入你要测得url地址
#URL = http://www.google.com

4.2.2 framework下新建browser_engine.py

封装对浏览器的操作

 

from selenium import webdriver
import configparser
import sys,os
class Browser(object):

   
    # 打开浏览器
    def open_browser(self):  
        config = configparser.ConfigParser()
        dir = os.path.abspath('.').split('src')[0]
        config.read( dir+"/config/config.ini")   
        browser = config.get("browserType", "browserName") 
        logger.info("You had select %s browser." % browser) 
        url = config.get("testServer", "URL")  
        if browser == "Firefox":  
            self.driver = webdriver.Firefox()  
        elif browser == "Chrome":  
            self.driver = webdriver.Chrome()    
        elif browser == "IE":  
            self.driver = webdriver.Ie() 
        self.driver.set_window_size(1920,1080) #分辨率
        #self.driver.maximize_window()#最大化
        self.driver.get(url) 
        return self.driver   
     
    # 打开url站点
    def open_url(self, url):  
        self.driver.get(url)  

    # 关闭浏览器    
    def quit_browser(self):
        self.driver.quit()

    # 浏览器前进操作
    def forward(self):
        self.driver.forward()

    # 浏览器后退操作
    def back(self):
        self.driver.back()
  
    # 隐式等待
    def wait(self, seconds):
        self.driver.implicitly_wait(seconds)

 

4.3 框架之-----日志配置 logger类
4.3.1 framework下新建logger.py

import logging
import time
import os
class Logger(object):
    def __init__(self, logger):
        '指定保存日志的文件路径，日志级别，以及调用文件,将日志存入到指定的文件中'
        
        # 创建一个logger
        self.logger = logging.getLogger(logger)  
        #self.logger.setLevel(logging.DEBUG)  
        # 创建一个handler，用于写入日志文件
        rq = time.strftime('%Y%m%d%H%M', time.localtime(time.time()))  
 
        log_dir = os.path.abspath('.').split('src')[0] + '/logs/'
        log_name = log_dir + rq + '.log'  
        fh = logging.FileHandler(log_name) 
         
        fh.setLevel(logging.INFO)    

        # 再创建一个handler，用于输出到控制台
        ch = logging.StreamHandler()  
        #ch.setLevel(logging.INFO)  
        ch.setLevel(logging.ERROR)
        # 定义handler的输出格式
        formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')  
        fh.setFormatter(formatter)  
        ch.setFormatter(formatter)  
        
        # 给logger添加handler
        self.logger.addHandler(fh)  
        self.logger.addHandler(ch)  


    def getlog(self):  
        return self.logger 

4.3.2 其他类中引用日志类
在其他类前面先导入日志类：

 

from framework.logger import Logger 
logger = Logger("XXXXX页面").getlog() 
# 在你想打印日志的地方加上： 
logger.info(XXXXXX) 
logger.error(XXXXX) #可参考下面的类

 

4.4框架之-----selenium二次封装 basepage类
framework下新建basepage.py封装对页面的基本操作，其中包含：查找元素、点击元素、输入、下拉选择、切换iframe，执行js等

import time  
from selenium.common.exceptions import NoSuchElementException  
from selenium.webdriver.common.action_chains import ActionChains
import os.path  
from framework.logger import Logger
from selenium.webdriver.support.select import Select
from selenium.webdriver.common.keys import Keys
from random import choice
logger = Logger("BasePage").getlog()

class BasePage(object):
    "定义一个页面基类，让所有页面都继承这个类，封装一些常用的页面操作方法到这个类"

    def __init__(self, driver):
        self.driver = driver

4.5框架之-----读表操作封装【现在有些方法不需要了，因为是从数据库读】

framework下新建readexcle.py,主要获取表中的数据
需先pip安装：xlrd

import xlrd
class ReadExcle(object):
    '''
    classdoc
    '''
    def __init__(self,file,tag='True'):
        self.file=file

        sheetname:excel文件的具体sheet名称
        n：开始行数，从第n行开始读
        num:读取num行
    '''
