Python Pytest模拟eval导入的函数

不确定这是否可行，但有没有办法模拟eval导入的函数

例如：

a、 派克

b、 派克

测试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'

---

使用

monkeypatch

夹具：

# test_a.py

def test_code(monkeypatch):
    monkeypatch.setattr('b.mockME', lambda: 'mocked code')
    assert_me = a.code()
    assert assert_me == 'mocked code'

---

谢谢你，维姆！正是我要找的！我不知道有这样的事情存在。该去研究了。

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'

# test_a.py

def test_code(monkeypatch):
    monkeypatch.setattr('b.mockME', lambda: 'mocked code')
    assert_me = a.code()
    assert assert_me == 'mocked code'
