1 项目背景

https://passport.csdn.net/login CSDN登录页面

2 功能实现

· 自动运行用例

· 自动生成测试报告

· 自动断言与截图

· 自动将最新测试报告发送到指定邮箱

· 数据，页面元素分离

· PageObject+Unittest+ddt数据驱动用例

· 执行日志、分布式执行

3 项目架构

4 浏览器Driver定义

from common.readFile import ReadFile
from common.logger import Logger
from selenium import webdriver
logger = Logger()
from selenium.webdriver import Remote
class Browser():
    def __init__(self):
        config = ReadFile()
        self.browser = config.readConfig("Browser", "browser")
        self.host = config.readConfig("host","host")
        logger.info("You had select {} host {} browser.".format(self.host,self.browser))
    def driver(self):
        """
        启动浏览器驱动
        :return: 返回浏览器驱动URL
        """
        try:
            # driver = webdriver.Chrome()
            driver = Remote(command_executor='http://' + self.host + '/wd/hub',
                            desired_capabilities={ 'platform': 'ANY',
                                                   'browserName': self.browser,
                                                   'version': "",
                                                   'javascriptEnabled': True
                                                }
                            )
            return driver
        except Exception as msg:
            print("驱动异常-> {0}".format(msg))

5 用例运行前后的环境准备工作

import unittest
from common.driver import Browser
class StartEnd(unittest.TestCase):
    def setUp(self):
        self.driver = Browser().driver()
        self.driver.implicitly_wait(10)
        self.driver.maximize_window()
    def tearDown(self):
        self.driver.quit()

6 工具方法模块

主要封装一些公共的方法如：截图，查找最新报告。

import time
from selenium import webdriver
import os,sys
sys.path.append(os.path.dirname(os.path.dirname(os.path.dirname(__file__))))
from config import setting
def inser_img(driver):
    # 指定截图存放的根目录路径
    screen_dir = setting.TEST_REPORT + '/imges/'
    rq = time.strftime('%Y%m%d%H%M%S', time.localtime(time.time()))
    screen_name = screen_dir + rq + '.png'
    driver.get_screenshot_as_file(screen_name)
    print('screenshot:' + screen_name)
#查找最新的测试报告
def latest_report(report_dir):
    lists = os.listdir(report_dir)
    lists.sort(key=lambda fn: os.path.getatime(report_dir + '\\' + fn))
    file = os.path.join(report_dir, lists[-1])
    return file
def latest_report_img(report_dir):
    lists = os.listdir(report_dir)
    lists.sort(key=lambda fn: os.path.getatime(report_dir + '\\' + fn))
    file = os.path.join(report_dir, lists[-1])
    return file
