如何验证在我的方法中的特定列表上进行的调用？

class MyClass:
    def __init__(self):
        self.call_list = []

    def my_method(self, param):
        # 执行你的方法逻辑
        result = param * 2

        # 记录调用信息
        call_info = {
            'param': param,
            'result': result,
            'timestamp': datetime.now()
        }
        self.call_list.append(call_info)

        return result

    def verify_calls(self, expected_calls):
        # 验证调用
        for expected_call in expected_calls:
            found = False
            for call_info in self.call_list:
                if call_info['param'] == expected_call['param']:
                    found = True
                    # 在这里可以编写验证逻辑，比如验证返回值是否正确等
                    break

            if not found:
                raise AssertionError(f"Expected call with param {expected_call['param']} not found")

# 创建对象并调用方法
obj = MyClass()
obj.my_method(10)
obj.my_method(20)

# 验证调用
expected_calls = [
    {'param': 10},
    {'param': 20}
]
obj.verify_calls(expected_calls)
