Selenium PageObject设计模式

简介

PageObject是Selenium自动化测试项目开发实践的最佳设计模式之一，通过对界面元素的封装减少冗余代码，同时在后期维护中，若元素定位发生变化，只需要调整页面元素封装的代码，提高测试用例的可维护性。

实践案例

1.封装BasePage

from selenium import webdriver
from  time import sleep

class Page():
    '''页面基础类'''

    #初始化
    def __init__(self, dirver):
        self.base_url = 'https://passport.csdn.net'
        self.driver = dirver
        self.timeout = 30

    #打开不同的子页面
    def _open(self, url):
        url_ = self.base_url + url
        print("Test page is： %s" %url_)
        self.driver.maximize_window()
        self.driver.get(url_)
        sleep(2)
        assert self.driver.current_url == url_, 'Did ont land on %s' % url_

    def open(self):
        self._open(self.base_url)

    def quit(self):
        self.driver.quit()

    #元素定位方法封装
    def find_element(self,*loc):
        return self.driver.find_element(*loc)

if __name__ == '__main__':
    driver = webdriver.Chrome()
    BsPg = Page(driver)
    BsPg._open('/login')
    BsPg.quit()

2.封装Loginpage

from BasePage import *
from selenium.webdriver.common.by import By
from selenium import webdriver

class LoginPage(Page):
    '''首页登录页面'''

    url='/login'

    #定位器
    username_loc=(By.NAME,'all')
    password_loc=(By.NAME,'pwd')
    submit_loc=(By.CLASS_NAME,'btn-primary')
    click_loc=(By.LINK_TEXT,'账号密码登录')

    #用户名输入框元素
    def type_username(self,username):
        self.find_element(*self.username_loc).clear()
        self.find_element(*self.username_loc).send_keys(username)

    #密码输入框元素
    def type_password(self,password):
        self.find_element(*self.password_loc).clear()
        self.find_element(*self.password_loc).send_keys(password)

    #登录按钮元素
    def type_submit(self):
        self.find_element(*self.submit_loc).click()

    #点击切换登录方式
    def type_click(self):
        self.find_element(*self.click_loc).click()
#登录功能模块封装
def test_user_login(driver,username,password):
    '''测试用户名密码是否可以登录'''
    login_page=LoginPage(driver)
    login_page.open()
    login_page.type_click()
    sleep(2)
    login_page.type_username(username)
    login_page.type_password(password)
    sleep(2)
    login_page.type_submit()

if __name__ == '__main__':
    driver = webdriver.Chrome()
    test_user_login(driver,'testname','testpwd')

3.封装登录测试模块

from LoginPage import *
from selenium import webdriver

driver=webdriver.Chrome()

username = '51zxw'
password = '123456'
test_user_login(driver, username, password)

sleep(3)
driver.quit()
