Python 模拟补丁 ldap3 搜索响应
Python Mock patch ldap3 search response
我正在尝试模拟以下函数,但我不确定如何模拟连接响应:
def get_user_res(user, pass):
res = None
server = Server('my_server')
connnection = Connection(server, user, pass, strategy=SAFE_SYNC, auto_bind=True)
if connection.bind():
connection.search(search_base, search_filter, SUBTREE)
res = connection.response
connection.unbind()
return res
@mock.patch("ldap3.Server")
@mock.patch("ldap3.Connection.response")
def test_get_user_res(mock_connection, mock_server):
mock_connection.return_value = ""
retrived_res = get_user_res("fake_user","fake_password")
expected_res = ""
assert retrived_res == expected_res
根本问题是你在嘲笑错误的东西。如果你有一个名为 ldapclient.py
的文件,其中包含你的 get_user_rest
方法,就像这样(请注意,我已经重写了一些内容以使我们在编写测试时的生活更轻松):
import ldap3
server = ldap3.Server('my_server')
search_base = 'dc=example, dc=com'
def get_user_res(user, password, search_filter=None):
res = None
connection = ldap3.Connection(
server, user, password,
client_strategy=ldap3.SAFE_SYNC, auto_bind=True)
if connection.bind():
res = connection.search(search_base, search_filter, ldap3.SUBTREE)
connection.unbind()
return res
然后你需要模拟的是 ldap3.Connection
class。但是由于您的测试在不同的模块中,您需要调用 @mock.patch('ldapclient.ldap3.Connection)
,假设您的测试定义如下:
import ldap3
from unittest import mock
import ldapclient
@mock.patch("ldapclient.ldap3.Connection")
def test_get_user_res(mock_connection_class):
mock_connection = mock.Mock()
mock_connection.search.return_value = 'fake_return'
mock_connection_class.return_value = mock_connection
retrived_res = ldapclient.get_user_res("fake_user", "fake_password")
expected_res = "fake_return"
assert retrived_res == expected_res
这里有几点需要注意:
- 如前所述,因为我们有
import ldapclient
,所以我们需要mock ldapclient.ldap3.Connection
。
- 我们使
ldap3.Connection
class return 成为一个新的 mock.Mock
对象,因为我们希望能够模拟对象上的方法 returned调用 connection = ldap3.Connection(...)
时
- 我们将
search
方法 return 设为假值,以确保它按预期被调用。
