Python 第三方软件包的mock.patch（）的Pytest路径

为什么第一个案例成功。但是第二个案例失败了。断言者错误：预期“詹金斯”会被调用

两个文件在同一个根文件夹中。

不太清楚Python的

导入

和

自。。。导入…

但是如果您使用来自的

。。。导入…

，模拟显示如下：

util.py

from jenkinsapi.jenkins import Jenkins
import os

class Util:
    @staticmethod
    def rm(filename):
        os.remove(filename)

    @staticmethod
    def get_jenkins_instance():

            password='password',
            ssl_verify=False,
            lazy=True)

import pytest
from util import Util

def test_util_remove(mocker):
    m = mocker.patch('os.remove')

def test_util_get_instance(mocker):
    m = mocker.patch('jenkinsapi.jenkins.Jenkins')
    Util.get_jenkins_instance()

要模仿詹金斯，你必须编写下一个mock.patch（“utils.Jenkins”），哇，它很管用@alex2007v只是因为我导入它的方式不同，所以

操作系统不需要
utils
。删除
？您作为模块导入的操作系统，对于操作系统，您不需要此
