如何为errbot模拟助手方法

pip install mock

# my_plugin.py
class MyPlugin(object):
    def get_weather(self, city):
        # 实际实现会调用外部 API 获取天气信息
        pass

import unittest
from unittest.mock import patch
from errbot import BotPlugin, botcmd
from my_plugin import MyPlugin

class TestMyPlugin(unittest.TestCase):
    @patch('my_plugin.MyPlugin.get_weather')
    def test_get_weather(self, mock_get_weather):
        # 设置模拟方法的返回值
        mock_get_weather.return_value = 'Sunny'

        plugin = MyPlugin()
        result = plugin.get_weather('New York')
        self.assertEqual(result, 'Sunny')

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

from errbot import BotPlugin, botcmd, testing

class TestMyPlugin(testing.BotTestCase):
    def test_my_plugin(self):
        # 加载插件
        self.load_plugin('my_plugin.MyPlugin')

        # 测试命令
        self.assertCommand('!get_weather New York', 'Sunny')

if __name__ == '__main__':
    testing.run_bot_tests()

class MyPlugin(object):
    def get_weather(self, city):
        # 实际实现会调用外部 API 获取天气信息
        pass

def test_my_plugin():
    plugin = MyPlugin()
    plugin.get_weather = lambda city: 'Sunny'  # 手动模拟方法
    result = plugin.get_weather('New York')
    assert result == 'Sunny'

if __name__ == '__main__':
    test_my_plugin()
