fakeldap 0.6.1

安装

获取并安装代码：

$ git clone git://github.com/30loops/fakeldap.git
$ cd fakeldap
$ python setup.py install

如果需要，可以运行测试：

$ python setup.py nosetests

用法

MockLDAP类替换python ldap模块的LDAPObject。 最简单的方法是覆盖ldap.initialize以返回 MockLDAP而不是LDAPObject。下面的例子使用michael foord的 Mock实现这一目标的库：

import unittest
from mock import patch
from fakeldap import MockLDAP


_mock_ldap = MockLDAP()

class YourTestCase(unittest.TestCase):
    def setUp(self):
        # Patch where the ldap library is used:
        self.ldap_patcher = patch('app.module.ldap.initialize')
        self.mock_ldap = self.ldap_patcher.start()
        self.mock_ldap.return_value = _mock_ldap

    def tearDown(self):
        _mock_ldap.reset()
        self.mock_ldap.stop()

模拟LDAP对象实现以下LDAP操作：

• 简单绑定
• 搜索
• 比较s
• 修改s
• 删除s
• 添加s
• 重命名s

这是一个如何将MockLDAP与固定返回值一起使用的示例：

def test_some_ldap_group_stuff(self):
    # Define the expected return value for the ldap operation
    return_value = ("cn=testgroup,ou=group,dc=30loops,dc=net", {
        'objectClass': ['posixGroup'],
        'cn': 'testgroup',
        'gidNumber': '2030',
    })

    # Register a return value with the MockLDAP object
    _mock_ldap.set_return_value('add_s',
        ("cn=testgroup,ou=groups,dc=30loops,dc=net", (
            ('objectClass', ('posixGroup')),
            ('cn', 'testgroup'),
            ('gidNumber', '2030'))),
        (105,[], 10, []))

    # Run your actual code, this is just an example
    group_manager = GroupManager()
    result = group_manager.add("testgroup")

    # assert that the return value of your method and of the MockLDAP
    # are as expected, here using python-nose's eq() test tool:
    eq_(return_value, result)

    # Each actual ldap call your software makes gets recorded. You could
    # prepare a list of calls that you expect to be issued and compare it:
    called_records = []

    called_records.append(('simple_bind_s',
        {'who': 'cn=admin,dc=30loops,dc=net', 'cred': 'ldaptest'}))

    called_records.append(('add_s', {
        'dn': 'cn=testgroup,ou=groups,dc=30loops,dc=net",
        'record': [
            ('objectClass', ['posixGroup']),
            ('gidNumber', '2030'),
            ('cn', 'testgroup'),
            ]}))

    # And again test the expected behaviour
    eq_(called_records, _mock_ldap.ldap_methods_called_with_arguments())

除了固定特定调用的返回值外，还可以模拟一个完整的调用 具有条目目录的LDAP服务器：

# Create an instance of MockLDAP with a preset directory
tree = {
    "cn=admin,dc=30loops,dc=net": {
            "userPassword": "ldaptest"
    }
}
mock_ldap = MockLDAP(tree)

record = [
    ('uid', 'crito'),
    ('userPassword', 'secret'),
]
# The return value I expect when I add another record to the directory
eq_(
    (105,[],1,[]),
    mock_ldap.add_s("uid=crito,ou=people,dc=30loops,dc=net", record)
)

# The expected directory
directory = {
    "cn=admin,dc=30loops,dc=net": {"userPassword": "ldaptest"},
    "uid=crito,ou=people,dc=30loops,dc=net": {
        "uid": "crito", "userPassword": "secret"}
}
# Compare the expected directory with the MockLDAP directory
eq_(directory, mock_ldap.directory)
