import unittest


def sum_number(a, b):
    return a + b


class MyTestCase(unittest.TestCase):
    # def test_something(self):
    #     self.assertEqual(True, False)
    @classmethod
    def setUpClass(cls) -> None:  # setupClass方法可以保证测试用例执行之前默认执行一次
        print(‘setupClass‘)

    def setUp(self) -> None:
        print(‘setup‘)

    def test_sum_int(self):
        self.assertEqual(sum_number(1, 2), 3)
        self.assertEqual(sum_number(100, 200), 300)

    def test_sum_number(self):
        self.assertEqual((1.1, 2.2), 3.3)

    @classmethod
    def tearDownClass(cls) -> None:  # tearDownClass方法可以保证测试用例执行之后默认执行一次
        print(‘tearDownClass‘)

    def tearDown(self) -> None:
        print(‘tearDown‘)

    unittest.main()
