unittest单元测试框架之数据驱动应用 -学习笔记(三)

1.数据驱动(文件)

2.parameterized

　　支持pip安装,pip install parameterized

　　例子:

import unittest
from selenium import webdriver
from parameterized import parameterized

from operation.customer.design import Design
from operation.customer.login import Login

class TestSingleCreate(unittest.TestCase):

　　# 通过 parameterized实现参数化
　　@parameterized.expand([
    　　("customer"),
    　　("artist"),
    　　])  # @parameterized.expand()来装饰测试用例
　　def test_single_create_customer(self, role):
   　　 """普通用户/艺术家定制添加图片，显示上传图片弹窗"""
    　　Login().login_role(self.driver, role)

    　　single_create_customer = Design()
    　　uploadimage_alert_text = single_create_customer.add_image(self.driver)
    　　self.assertEqual(uploadimage_alert_text, "upload")

if __name__ == '__main__':
    unittest.main(verbosity=2)

注:此处必须要用unittest.main()方法执行用例,否则会报错!!!如下
