Selenium Webdriver 编写UI自动化测试脚本

使用Selenium Webdriver 编写UI自动化测试脚本的设计方法非常多，但是大体都分为

1. 元素定位
2. 业务逻辑
3. 断言处理

这里对WebDriver Python 的Page Objects 设计模式就行下整理，这个模式采用面向对象的思想，把每个页面看作是一个的对象，页面的内的的所有的元素还有业务逻辑都被看作是是属性和方法

class page_name():

  def action1():
    ....

  def action2():
    ....

  def action3():
    ....

设计结构

基本结构分为四层

• BasePage (封装WebDriver 的基础方法)
• PageElement (页面对象类)
• PageLOctors (页面坐标路径)
• TestCase (测试用例)

Demo

这里拿小米官网的登陆做一个例子

BasePage/BaseDriver.py

# -*- coding:utf-8 -*-

# webdriver page object 基础公用方法
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

class BaseDriver(object):

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

	# 打开指定url
	def open_url(self, url, pagetitle):
		self.driver.get(self.url)
		self.driver.maximize_window()
		print self.driver.title
		assert self.pagetitle in self.driver.title

	# 根据传入坐标,返回元素
	def get_element(self, *loc):
		element = self.driver.find_element(*loc)
		return element

	# 根据传入坐标,返回所有匹配的元素,返回list
	def get_elements(self, *loc):
		elementlist  = self.driver.find_elements(*loc)
		return elementlist

	# webdriver 调用selenium 的方法,判断元素是否存
	def is_element_exist(self, *loc):
		try:
			self.driver.find_element(*loc)
			self.driver.find_elements(*loc)
			return  True
		except:
			return False

	# webdriver 调用selenium 的方法,判断元素是否存
	def is_element_display(self, *loc):
		try:
			if self.driver.find_element(*loc).is_displayed() or self.driver.find_elements(*loc).is_displayed():
				return  True
			else:
				return False
		except:
		 	return False

	# 判断元素是否显示
	def wait_element_display(self, time, *loc):
		try:
			WebDriverWait(self.driver, time).until(
				EC.presence_of_element_located(*loc))
			return  True
		except:
			return  False

	# 判断元素是否可视
	def wait_element_visible(self, time, *loc):
		try:
			WebDriverWait(self.driver, time).until(
				EC.visibility_of_element_located(*loc))
			return  True
		except:
			return False

	# 执行js 脚本
	def exec_js(self, script):
		self.driver.execute_script(script)

	# 刷新网页
	def refresh_page(self):
		self.driver.refresh()

PageElement/login_page.py

# -*- coding:utf-8 -*-

from BasePage.BaseDriver import BaseDriver
from PageLoctors.login_page_loc import LoginPageLoc

class LoginPage(BaseDriver):

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

	def input_username(self, username):
		print self.get_element(*LoginPageLoc.user)
		self.get_element(*LoginPageLoc.user).send_keys(username)

	def input_password(self, password):
		self.get_element(*LoginPageLoc.password).send_keys(password)

	def click_login_button(self):
		self.get_element(*LoginPageLoc.loginbut).click()

PageLocotrs/Login_page_loc.py

# -*- coding:utf-8 -*-

from selenium.webdriver.common.by import By

class LoginPageLoc(object):

	user = (By.ID, "username")
	password = (By.ID, "pwd")
	loginbut = (By.ID, "login-button")

TestCase/xiaomi_Test.py

# -*- coding:utf-8 -*-

import unittest

from selenium import webdriver
from PageElement.login_page import  LoginPage

class XiaoMiTest(unittest.TestCase):

	def setUp(self):
		self.driver = webdriver.Chrome()
		self.driver.get("url......")
		self.driver.maximize_window()
		self.driver.implicitly_wait(30)

		self.username = "xxxxxxxxx"
		self.password = "xxxxxxxxx"

	def test_login(self):
		loginPage = LoginPage(self.driver)
		loginPage.input_username(self.username)
		loginPage.input_password(self.password)
		loginPage.click_login_button()

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

if __name__ == '__main__':
    unittest.main()
