一.设计测试用例

1.分析我之前写的登录脚本：

from selenium import webdriver
import time
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait

url = 'http://www.maiziedu.com/'
login_path = '/html/body/div[2]/div/div/div/div/a[2]'
account = 'xxx' #这里需填实际的账号
pwd = 'maizi123456'              #预先设定好网址和账号密码

def get_ele_times(driver,times,func):
    return WebDriverWait(driver,times).until(func)  #等待方法

def login_test():
    driver = webdriver.Firefox()   #open firefox
    driver.get(url)               #打开url
    time.sleep(1)
    driver.maximize_window()    #最大化窗口
    
    ele_login = get_ele_times(driver,10,\
                              lambda driver:driver.find_element_by_xpath(login_path))
    ele_login.click()  #找到登录，然后点击
    #相当于：driver.find_element_by_link_text(login_text).click()


    account_ele = driver.find_element_by_xpath('//*[@id="id_account_l"]')
    account_ele.send_keys('')
    account_ele.send_keys(account)

    password_ele = driver.find_element_by_xpath('//*[@id="id_password_l"]')
    password_ele.send_keys('')
    password_ele.send_keys(pwd)

    driver.find_element_by_xpath('//*[@id="login_btn"]').click()
    try:
        driver.find_element_by_link_text('该账号不正确')
        print ("ACCOUNT AND PWD ERROR!")
    except:
         print ("ACCOUNT AND PWD RIGHT!")

if __name__ == '__main__':
    login_test()

2.分析脚本功能是否可以模块化

3.模块化与数据隔离

4.修改后的模型

 

二.测试用例模块化

2.模块化的代码：

from selenium import webdriver
import time
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait

url = 'http://www.maiziedu.com/'
login_xpath = '/html/body/div[2]/div/div/div/div/a[2]'
account = 'XXX'
pwd = 'maizi123456'              #预先设定好网址和账号密码

def openBrower():                    #配置浏览器
    webdriver_handle = webdriver.Firefox()
    return webdriver_handle      
                                      
def openUrl(handle,url):               #打开url
    handle.get(url)

def get_ele_times(driver,times,func):
    return WebDriverWait(driver,times).until(func)  #等待方法    

def findElement(driver,arg):
    '''
     arg must be dict
     1.user_xpath：用户名
     2.pwd_xpath：密码
     3.login_xpath：登录按钮
     return useEle,pwdEle,loginEle
    '''
         
    useEle = driver.find_element_by_xpath(arg['user_xpath'])
    pwdEle = driver.find_element_by_xpath(arg['pwd_xpath'])
    loginEle = driver.find_element_by_xpath(arg['login_xpath'])
    return useEle,pwdEle,loginEle

def sendVals(eletuple,arg):
    '''
    ele tuple
    account:uname,pwd
    '''
    listkey = ['uname','pwd']
    i = 0
    for key in listkey:
        eletuple[i].send_keys('')
        eletuple[i].clear()
        eletuple[i].send_keys(arg[key])
        i+=1
    eletuple[2].click()    
def checkResult(driver,text):
    try:
        driver.find_element_by_link_text(test)
        print ("ACCOUNT AND PWD ERROR!")
    except:
         print ("ACCOUNT AND PWD RIGHT!")
    
def login_test():
    driver = openBrower()
    openUrl(driver,url)
    driver.maximize_window()
    ele_login = get_ele_times(driver,10,lambda driver:driver.find_element_by_xpath(login_xpath))
    ele_login.click() 
                           #字典
    ele_dict = {'user_xpath':'//*[@id="id_account_l"]',\
                'pwd_xpath':'//*[@id="id_password_l"]','login_xpath':'//*[@id="login_btn"]'}
    account_dict = {'uname':account,'pwd':pwd}
    
    ele_tuple = findElement(driver,ele_dict)   #接收字典的值
    
    sendVals(ele_tuple,account_dict)
    checkResult(driver,'该账号不正确')
    driver.find_element_by_link_text('退出').click()
    
if __name__ == '__main__':
    login_test()
