综合练习：web端Python自动化测试

一、项目：针对百度首页搜索功能的测试：python+selenium+unittest

1、page object 封装页面元素。

from poium import Page, NewPageElement

class BaiduPage(Page):
    """封装百度Page层"""
    search_input = NewPageElement(id_="kw",describe="搜索框")
    search_button = NewPageElement(id_="su",describe="搜索按钮")
    setting = NewPageElement(id_="s-usersetting-top",describe="设置按钮")
    search_setting = NewPageElement(link_text="搜索设置")
    high_level_setting = NewPageElement(link_text="高级设置")
    save_setting = NewPageElement(link_text="保存设置")
    language_setting = NewPageElement(id_ = "SL_1",describe="简体中文")

2、封装谷歌浏览器启动操作

import unittest
from selenium import webdriver

class Launch_Brower(unittest.TestCase):
    """开启/关闭 谷歌浏览器"""

    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Chrome()
        cls.baidu_url = "https://www.baidu.com/"


    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()

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

3、test case:用parameterized.expand()或ddt.file_data实现参数化。

import unittest,csv,codecs, os, sys
base_path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, base_path)
from common.launch_brower import Launch_Brower
from page.baidu_page import BaiduPage
from time import sleep
from parameterized import parameterized
from itertools import islice
from ddt import ddt,file_data,unpack


@ddt
class TestSearchKeyword(Launch_Brower):

    def search_keyword(self,keyword):
        page = BaiduPage(self.driver)
        page.get(self.baidu_url)
        page.search_input.send_keys(keyword)
        page.search_button.click()
        sleep(2)

    def get_data(file_path):
        
        """读取参数化文件baidu_data.csv"""
        data = []
        with codecs.open(file_path , "r") as f:
            temp = csv.reader(f)
            for i in islice(temp,1,None):
                data.append(tuple(i))    
        return data

   
    @parameterized.expand(

        get_data(base_path +
        "/test_case/baidu_data/data_file.csv"))
                          
    def test_01_search_keyword(self,name,keyword):
        
        self.search_keyword(keyword)
        title = self.driver.title
        self.assertEqual(title, keyword + "_百度搜索")
      
   
    
    @file_data("ddt.json")
    @unpack
    def test_02_search_keyword(self,keyword):
        self.search_keyword(keyword)
        title = self.driver.title
        self.assertEqual(title, keyword + "_百度搜索")
    
               
if __name__=="__main__":
    unittest.main(verbosity=2)

4、调用HTMLTestRunner运行测试用例生成报告。

import time,unittest
from HTMLTestRunner import HTMLTestRunner
import time,sys
sys.path.append("./test_case")


if __name__=="__main__":

    test_dir = './test_case'
    suit = unittest.defaultTestLoader.discover(test_dir,pattern='test*.py')
    now_time = time.strftime("%Y-%m-%d %H_%M_%S")
    filename = './report/'+now_time+'_result.html'
    with open(filename, "wb") as fp:
        runner = HTMLTestRunner(stream=fp,
                            title='百度',
                            description="win 10",
                             verbosity=2)
                               
        runner.run(suit,rerun=0,save_last_run=False)
        fp.close()
