可以编写一个测试来测试AuthorizationPolicy对象吗？

import unittest
from myapp import AuthorizationPolicy

class AuthorizationPolicyTest(unittest.TestCase):

    def setUp(self):
        # 设置测试环境和依赖

    def tearDown(self):
        # 清理测试环境和依赖

    def test_allow_access(self):
        # 测试允许访问的情况
        policy = AuthorizationPolicy()
        # 设置测试数据
        result = policy.check_access(user, resource)
        self.assertTrue(result)

    def test_deny_access(self):
        # 测试拒绝访问的情况
        policy = AuthorizationPolicy()
        # 设置测试数据
        result = policy.check_access(user, resource)
        self.assertFalse(result)

if __name__ == '__main__':
    unittest.main()
