import unittest


# 要测试的函数
def add_numbers(x, y):
    return x + y


# 编写测试类
class TestAddNumbers(unittest.TestCase):
    # 每个测试方法必须以"test_"开头
    def test_add_numbers_positive(self):
        result = add_numbers(2, 3)
        self.assertEqual(result, 5)  # 断言结果是否等于期望值

    def test_add_numbers_negative(self):
        result = add_numbers(-2, -3)
        self.assertEqual(result, -5)  # 断言结果是否等于期望值

    def test_add_numbers_zero(self):
        result = add_numbers(0, 0)
        self.assertEqual(result, 0)  # 断言结果是否等于期望值


# 运行测试
