在google测试框架中的两个测试用例之间共享数据

import unittest

class MyTestCase(unittest.TestCase):
    def setUp(self):
        self.shared_data = "This is shared data"
    
    def tearDown(self):
        self.shared_data = None
    
    def test_case1(self):
        # 使用共享数据
        self.assertEqual(self.shared_data, "This is shared data")
    
    def test_case2(self):
        # 使用共享数据
        self.assertEqual(self.shared_data, "This is shared data")
