问题描述
使用模拟单元测试 conn():
Unit testing conn() using mock:
app.py
test.py
错误:断言 mock_mysql.connect.assert_called_with
未被调用.
我认为这是因为Database_url"不在我修补的 os.environ 中,并且因为没有对 mysql_mock.connect 进行测试调用.
which i believe it is because 'Database_url' is not in my patched os.environ and because of that test call is not made to mysql_mock.connect.
问题:
1 我需要进行哪些更改才能使此测试代码正常工作?
1 what changes i need to make to make this test code work?
2.我也必须修补'urlparse'吗?
2.Do i also have to patch 'urlparse'?
推荐答案

参数调用 conn
:
You can try unittest.mock.patch.dict solution. Just call conn
with a dummy
argument:
或者,如果您不想修改原始功能,请尝试以下解决方案:
Or if you don't want to modify your original function try this solution:
