作业要求参见https://edu.cnblogs.com/campus/nenu/2018fall/homework/2146

1、测试随机生成

import unittest

from f4_1 import createOperator

class testCreateOperator(unittest.TestCase):
    def test_CreateOperator(self):
        print("单元测试开始：")
        operator = ["+", "-", "*", "/"]
        self.assertIn(createOperator(self),operator)
if __name__ == '__main__':
    unittest.main()

效果

二、测试生成四则运算试题

import unittest

from f4_1 import main

class testmain(unittest.TestCase):
    def test_main(self):
        print("单元测试开始：")

        self.assertIn(main(),20)
if __name__ == '__main__':
    unittest.main()
