環境準備
1.安裝ddt模組，開啟cmd輸入pip install ddt線上安裝



資料驅動原理
1.測試資料為多個字典的list型別

2.測試類前加修飾@ddt.ddt

3.case前加修飾@ddt.data()

4.執行後用例會自動載入成三個單獨的用例

import unittest
 
# 測試資料
test_data1 = [{"username": "zhangsan", "pwd": "zhangsan"},
             {"username": "lisi", "pwd": "lisi"},
             {"username": "wangwu", "pwd": "wangwu"},
             ]
test_data2 = [{"username": "wukong", "pwd": "wukong"},
             {"username": "wuneng", "pwd": "woneng"},
             {"username": "wujing", "pwd": "wujing"},
