[开发测试]python单元测试之unittest

setUp()：准备环境，执行每个测试用例的前置条件；
tearDown()：环境还原，执行每个测试用例的后置条件；
setUpClass()：必须使用@classmethod装饰器，所有case执行的前置条件，只运行一次；
tearDownClass()：必须使用@classmethod装饰器，所有case运行完后只运行一次；

import unittest
#要继承unittest.TestCase
class CalcTestcase(unittest.TestCase):
    def setUp(self) -> None:
        print("我是setUp")
    def test01(self):
        print("我是的测试方法test01")
    def test02(self):
        print("我是的测试方法test02")
    def test03(self):
        print("我是的测试方法test03")
    def tearDown(self) -> None:
        print("我是tearDown")
    @classmethod
    def setUpClass(cls) -> None:
         print("我是setUpClass")
    @classmethod
    def tearDownClass(cls) -> None:
            print("我是tearDownClass")
if __name__ == '__main__':
     unittest.main()
     #设置套件
     # suite = unittest.TestSuite()
     # #把测试方法添加到集合中，然后循环取值，在添加到套件里面输出
     # list = ["test01","test02","test03"]
     # for i in list:
     #     suite.addTest(CalcTestcase(i))

?开发代码：

class CalClass(object):
    def add(self,a,b):
        c = a+b
        return c
    def reduct(self,a,b):
        c = a-b
        return c
# c = CalClass()
# print(c.reduct(1,2))
if __name__ == '__main__':
    c = CalClass()
    print(c.reduct(1, 2))

进行测试开发代码：

import unittest
from demo.kaifa import CalClass
c = CalClass()
rr = c.add(2,3)
class CalcTestClass(unittest.TestCase):
    def setUp(self) -> None:
        print("我是setUp")

    def test01(self):
        self.assertEqual(5,rr)

    def tearDown(self) -> None:
        print("我是tearDown")

if __name__ == '__main__':
    unittest.main()
    # suite = unittest.TestSuite()
    # lists = ["test01","test02","test03"]
    # for i in lists:
    #     suite.addTest(CalcTestClass(i))
