python学习_模块化示例

以登陆为例，示例登陆写法

#1.流水写法，最基本写法
from selenium import webdriver


driver = webdriver.Firefox()
driver.get("https://test.xxx.com/login.jhtml")

driver.find_element_by_id("u_username").send_keys("jilu1219")
driver.find_element_by_id("u_password").send_keys("xxxxxx")
driver.find_element_by_id("u_submit").click()

#2.把登陆抽成方法，仍在同一个文档里头

from selenium import webdriver


def login(openUrl，username,password):
    driver.get(openUrl)
    driver.find_element_by_id("u_username").send_keys(username)
    driver.find_element_by_id("u_password").send_keys(password)
    driver.find_element_by_id("u_submit").click()
    


driver = webdriver.Firefox() 
  
login("https://test.xxx.com/login.jhtml"，"jilu1219","xxxxxx") 
    

#3.把登陆抽成方法login.py，与实际登陆代码test0424001.py放在同一个目录下

#login.py 代码

#coding=utf-8

from selenium import webdriver

def login(openUrl,username,password):
    driver = webdriver.Firefox()
    driver.get(openUrl)
    driver.find_element_by_id("u_username").send_keys(username)
    driver.find_element_by_id("u_password").send_keys(password)
    driver.find_element_by_id("u_submit").click()


#################################
#实际登陆代码，保存为test0424001.py
from selenium import webdriver
import login

    
driver = webdriver.Firefox()

login.login("https://test.xxxx.com/login.jhtml","jilu1219","xxxxxx")
    

#4.把登陆抽成一个方法login.py，与实际登陆代码test0424001.py放在不同目录下

现目录如下：

D:Desktop estPython est0424001.py

D:Desktop estPythonpubliclogin.py

D:Desktop estPythonpublic\__init__.py

#当把login.py 抽到public目录下时，需在此目录下新建__init__.py 空文件

#login.py 代码 ，未变
#coding=utf-8

from selenium import webdriver



def login(openUrl,username,password):
    driver = webdriver.Firefox()
    driver.get(openUrl)
    driver.find_element_by_id("u_username").send_keys(username)
    driver.find_element_by_id("u_password").send_keys(password)
    driver.find_element_by_id("u_submit").click()
    
    

#test0424001.py 代码

#coding=utf-8

from selenium import webdriver

import sys
sys.path.append("public")  #注意需扩展path路径

from public import login

driver = webdriver.Firefox()

login.login("https://test.xxxx.com/login.jhtml","jilu1219","xxxxxx")

 #5.在以上的基础上把登陆网址、用户名、密码参数化，把数据保存在一个.csv文件中

现目录如下：

D:Desktop estPython est0424004.py

D:Desktop estPythonpubliclogin.py

D:Desktop estPythonpublic\__init__.py

D:Desktop estPythonpublicloginData.py

D:Desktop estPythondataloginData.csv

#loginData.py 代码

#coding=utf-8
import csv

def loginData():
    my_file = "D:\Desktop\testPython\data\loginData.csv"
    datas=csv.reader(file(my_file,'rb'))
    for data in datas:
        openUrl = data[0]
        username = data[1]
        password = data[2]

    return openUrl,username,password;

#login.py 代码

#coding=utf-8

from selenium import webdriver
import time


def login(openUrl,username,password):
    driver = webdriver.Firefox()
    driver.get(openUrl)
    driver.find_element_by_id("u_username").send_keys(username)
    driver.find_element_by_id("u_password").send_keys(password)
    driver.find_element_by_id("u_submit").click()
    

    

#test0424004.py 代码， 主要测试用例文件

#coding=utf-8

from selenium import webdriver

import sys
sys.path.append("public")  #注意需扩展path路径

from public import login
from public import loginData
import csv

driver = webdriver.Firefox()

openUrl,username,password=loginData.loginData()  #注意

login.login(openUrl,username,password)

#6.若导入数据有多行需参数化，则在#5的基础上需做些 小调整。需调整loginData.py 及test0424004.py 代码，其余保持不变。login.py保持不变。

#loginData.py daima

#coding=utf-8

import csv

def loginData():
    my_file = "D:\pythonTest\dataloginData.csv"
    datas = csv.reader(file(my_file,'rb'))
    return datas  #注意

#test0424004.py代码

#coding=utf-8

from selenium import webdriver
import time
import sys
sys.path.append("public")

from public import login
from public import loginData
import csv

driver = webdriver.Firefox()

#注意通过循环取出
datas=loginData.loginData()
for data in datas:
    openUrl = data[0]
    username = data[1]
    password = data[2]
    login.login(openUrl,username,password)
    

 #7.若导入的csv有表头，则#6不适用，需再调整。需调整test0424004.py。login.py 不变。loginData.py不要了。

#test0424004.py代码调整

import time
import sys
sys.path.append("public")

from public import login

import csv

driver = webdriver.Firefox()


#读取csv文件，文档有表头
with open('D:pythonTestdataloginData02.csv','rb') as csvfile:
        reader = csv.DictReader(csvfile)
        urls = []
        usernames = []
        passwords= []
        for row in reader:
            if row['if_excute'] != 'if_excute':
                url = row['url']
                username = row['username']
                password = row['password']
                urls.append(url)
                usernames.append(username)
                passwords.append(password)

        #print urls
        #print passwords
        #print usernames

i = 0
while i <len(urls):
    login.login(urls[i],usernames[i],password[i])
    i += 1

#7.引入unittest框架 流水写法

#coding=utf-8
from selenium import webdriver
import time,unittest

class Aipaike_pc(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url="https://test.xxxx.com/login.jhtml"
        self.verificationErrors=[]
        self.accept_next_alert=True

    #登录用例，全部用例必须以test_命名
    def test_login(self):
        driver=self.driver
        driver.get(self.base_url)
        driver.find_element_by_id("u_username").send_keys("jilu1219")
        driver.find_element_by_id("u_password").send_keys("xxxxxx")
        driver.find_element_by_id("u_submit").click()
        time.sleep(5)
        driver.close()

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([],self.verificationErrors)

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