python+selenium九：ddt数据驱动

第一种，测试数据放在Excel里面

test_Login：

import unittest
import time
import ddt
import os
from selenium import webdriver
from SWYJR.common.readexcel import ExcelUtil
from SWYJR.encapsulation.LoginPage import Login

# # 获取xlsx路径
# curpath = os.path.dirname(os.path.realpath(__file__))
# testxlsx = os.path.join(curpath, "demo_api.xlsx")
#
# # 复制demo_api.xlsx文件到report下
# report_path = os.path.join(os.path.dirname(curpath), "report")
# reportxlsx = os.path.join(report_path, "result.xlsx")
# sheetName = "登录"
# testdata = readexcel.ExcelUtil(testxlsx, sheetName).dict_data()

excel = ExcelUtil("testdata.xlsx", "登录")
print(excel.dict_data())
datas = excel.dict_data()

@ddt.ddt
class LogIn(unittest.TestCase):
    ''' 登录测试 '''

    def setUp(self):
        self.driver = webdriver.Firefox()
        self.login = Login(self.driver)
        self.login.login_before()  # 调前置条件

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

    @ddt.data(*datas)
    def test_login(self, data):
        self.login.login(data['userName'], data['psw'])
        self.text = self.login.exit_button()
        self.assertIn(data['result'], self.text)

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

 readExcel：

# coding:utf-8
import xlrd
class ExcelUtil():

    def __init__(self, excelPath, sheetName):
    #def __init__(self, excelPath, sheetName):
        self.data = xlrd.open_workbook(excelPath)
        self.table = self.data.sheet_by_name(sheetName)
        # 获取第一行作为key值
        self.keys = self.table.row_values(0)
        # 获取总行数
        self.rowNum = self.table.nrows
        # 获取总列数
        self.colNum = self.table.ncols

    def dict_data(self):
        if self.rowNum <= 1:
            print("总行数小于1")
        else:
            r = []
            j=1
            for i in range(self.rowNum-1):
                s = {}
                # 从第二行取对应values值
                values = self.table.row_values(j)
                for x in range(self.colNum):
                    s[self.keys[x]] = values[x]
                r.append(s)
                j+=1
            return r

if __name__ == "__main__":
    # filepath = "D:\test\web-project\5ke\testdata.xlsx"
    filepath = "E:\testdata.xlsx"
    sheetName = "登录"
    data = ExcelUtil(filepath, sheetName)
    print(data.dict_data())

第二种，搭建个数据库，测试数据放在数据库里面，如：MySQL（个人比较喜欢用数据库的方式做数据分离）

导入第三方库pymysql，进行二次封装

import unittest, ddt, urllib3
from interfaces.Process import login
from common.MySQL import MysqlUtil
urllib3.disable_warnings()

# 拿测试数据
datas = MysqlUtil("SELECT explanation, userName, password, expect FROM Login").mysql_getrows()
# print(datas)

@ddt.ddt
class LogIn(unittest.TestCase):
    ''' 登录测试 '''

    @ddt.data(*datas)
    def test_login(self, data):
        ''' 测试用例 '''
        self.user = data[1]
        print(f'
用户名：{self.user}')

        self.password = data[2]
        print(f'
密码：{self.user}')

        loginResult = login(self.user, self.password)[0]
        print(f'
预期结果: {data[3]} 
执行结果: {loginResult}')

        self.assertEqual(loginResult, data[3])

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