Pytest 模拟 eval 导入的函数

Question

不确定这是否可行，但有没有办法模拟 eval 导入的函数？

例如：

一个.py

import b

def code():

    me = 'ME'

    should_be_changed = eval('b.mock' + me + '()')

    return should_be_changed

b.py

def mockME():

    return 'Dummy code'

test_a.py

import a

import pytest

from unittest.mock import patch

def test_code():

    #with patch('patch mockME somehow?', return_value='mocked code') as mock_mockME:

        assert_me = a.code()

    assert assert_me == 'mocked code'
