本文开始一步一步介绍,如何创建自己的第一个自动化测试框架。这一篇,我们介绍,如何封装自己的日志类和浏览器引擎类。
相关步骤:
1. 打开PyCharm,创建如下格式的项目层级结构,文件名称和我保持一样;
2. 相关文件代码如下
配置文件config.ini相关设计如下:
# this is config file, only store browser type and server URL
[browserType]
#browserName = Firefox
browserName = Chrome
#browserName = IE
[testServer]
URL = https://www.baidu.com
#URL = www.google.com
浏览器引擎类browser_engine.py相关脚本代码如下:
# -*- coding:utf-8 -*-
import ConfigParser
import os.path
from selenium import webdriver
from framework.logger import Logger
logger = Logger(logger="BrowserEngine").getlog()
class BrowserEngine(object):
dir = os.path.dirname(os.path.abspath('.')) # 注意相对路径获取方法
chrome_driver_path = dir + '/tools/chromedriver.exe'
ie_driver_path = dir + '/tools/IEDriverServer.exe'
def __init__(self, driver):
self.driver = driver
# read the browser type from config.ini file, return the driver
def open_browser(self, driver):
config = ConfigParser.ConfigParser()
# file_path = os.path.dirname(os.getcwd()) + '/config/config.ini'
file_path = os.path.dirname(os.path.abspath('.')) + '/config/config.ini'
config.read(file_path)
#config.read(file_path,encoding='UTF-8'), 如果代码有中文注释,用这个,不然报解码错误
browser = config.get("browserType", "browserName")
logger.info("You had select %s browser." % browser)
url = config.get("testServer", "URL")
logger.info("The test server url is: %s" % url)
if browser == "Firefox":
driver = webdriver.Firefox()
logger.info("Starting firefox browser.")
elif browser == "Chrome":
driver = webdriver.Chrome(self.chrome_driver_path)
logger.info("Starting Chrome browser.")
elif browser == "IE":
driver = webdriver.Ie(self.ie_driver_path)
logger.info("Starting IE browser.")
driver.get(url)
logger.info("Open url: %s" % url)
driver.maximize_window()
logger.info("Maximize the current window.")
driver.implicitly_wait(10)
logger.info("Set implicitly wait 10 seconds.")
return driver
def quit_browser(self):
logger.info("Now, Close and quit the browser.")
self.driver.quit()
日志类logger.py相关脚本代码如下:
# _*_ coding: utf-8 _*_
import logging
import os.path
import time
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_path = os.path.dirname(os.getcwd()) + '/Logs/' # 项目根目录下/Logs 保存日志
log_path = os.path.dirname(os.path.abspath('.')) + '/logs/'
# 如果case组织结构式 /testsuit/featuremodel/xxx.py , 那么得到的相对路径的父路径就是项目根目录
log_name = log_path + 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)
# 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
页面对象pageobject这里暂不用,下一篇介绍
测试脚本baidu_search.py相关脚本如下:
# coding=utf-8
import time
import unittest
from framework.browser_engine import BrowserEngine
class BaiduSearch(unittest.TestCase):
def setUp(self):
"""
测试固件的setUp()的代码,主要是测试的前提准备工作
:return:
"""
browse = BrowserEngine(self)
self.driver = browse.open_browser(self)
def tearDown(self):
"""
测试结束后的操作,这里基本上都是关闭浏览器
:return:
"""
self.driver.quit()
def test_baidu_search(self):
"""
这里一定要test开头,把测试逻辑代码封装到一个test开头的方法里。
:return:
"""
self.driver.find_element_by_id('kw').send_keys('selenium')
time.sleep(1)
try:
assert 'selenium' in self.driver.title
print ('Test Pass.')
except Exception as e:
print ('Test Fail.', format(e))
if __name__ == '__main__':
unittest.main()
工具包,这里把三个浏览器的driver文件都放根目录一个文件夹里,这样别人拷贝这个项目也不需要去下载这些文件。
运行测试脚本baidu_search.py,会在根目录下的logs文件生成日志文件,例如我:
2017-04-19 17:49:06,220 - BrowserEngine - INFO - You had select Chrome browser.
2017-04-19 17:49:06,220 - BrowserEngine - INFO - The test server url is: https://www.baidu.com
2017-04-19 17:49:10,049 - BrowserEngine - INFO - Starting Chrome browser.
2017-04-19 17:49:11,115 - BrowserEngine - INFO - Open url: https://www.baidu.com
2017-04-19 17:49:12,349 - BrowserEngine - INFO - Maximize the current window.
2017-04-19 17:49:12,349 - BrowserEngine - INFO - Set implicitly wait 10 seconds.
