#集合写入一个方法，main调用并启动

#添加一个测试集合，并添加Case

#指定并启动测试集合,运行集合方法

# -*- coding:utf-8 -*-

#集合可以写在main


import unittest

#指定并启动测试集合

  #添加测试集合Case,并启动
  suiteTest = unittest.TestSuite()
  suiteTest.addTest(TestCaseDemo('test_Case1'))

  #直接启动集合
  runner = unittest.TextTestRunner()
  runner.run(suiteTest)

# TestCase_Demo3.py
# -*- coding:utf-8 -*-

#包含集合，多集合

import unittest
from TestCase_Demo import TestCaseDemo

#添加不同的合集

#运行的时候，可以根据不同的要求，运行不同的Suite,或者全部运行，这样就方便管理每次运行的case
