Python:assertRaises()在引发时未捕获ldap.SERVER\u DOWN错误
提前谢谢你的帮助 我尝试测试以下类方法:Python:assertRaises()在引发时未捕获ldap.SERVER\u DOWN错误,python,python-unittest,python-ldap,Python,Python Unittest,Python Ldap,提前谢谢你的帮助 我尝试测试以下类方法: def _get_ldap_connection(self): """ Instantiate and return simpleldap.Connection object. Raises: ldap.SERVER_DOWN: When ldap_url is invalid or server is not reachable. """ try: ldap_c
def _get_ldap_connection(self):
"""
Instantiate and return simpleldap.Connection object.
Raises:
ldap.SERVER_DOWN: When ldap_url is invalid or server is
not reachable.
"""
try:
ldap_connection = simpleldap.Connection(
self.ldap_url, encryption='ssl', require_cert=False,
debug=False, dn=self.ldap_login_dn,
password=self.ldap_login_password)
except ldap.SERVER_DOWN:
raise ldap.SERVER_DOWN(
"The LDAP server specified, {}, did not respond to the "
"connection attempt.".format(self.ldap_url))
def test__get_ldap_connection(self):
"""
VERY IMPORTANT: This test refers to your actual config.json file.
If it is correctly populated, you can expect this test to fail.
"""
# Instantiate Class
test_extractor = SakaiLdapExtractor('config_files/config.json')
# Monkey with ldap server url to ensure error.
test_extractor.ldap_url = "invalid_ldap_url"
self.assertRaises(
ldap.SERVER_DOWN, test_extractor._get_ldap_connection())
下面是单元测试:
def _get_ldap_connection(self):
"""
Instantiate and return simpleldap.Connection object.
Raises:
ldap.SERVER_DOWN: When ldap_url is invalid or server is
not reachable.
"""
try:
ldap_connection = simpleldap.Connection(
self.ldap_url, encryption='ssl', require_cert=False,
debug=False, dn=self.ldap_login_dn,
password=self.ldap_login_password)
except ldap.SERVER_DOWN:
raise ldap.SERVER_DOWN(
"The LDAP server specified, {}, did not respond to the "
"connection attempt.".format(self.ldap_url))
def test__get_ldap_connection(self):
"""
VERY IMPORTANT: This test refers to your actual config.json file.
If it is correctly populated, you can expect this test to fail.
"""
# Instantiate Class
test_extractor = SakaiLdapExtractor('config_files/config.json')
# Monkey with ldap server url to ensure error.
test_extractor.ldap_url = "invalid_ldap_url"
self.assertRaises(
ldap.SERVER_DOWN, test_extractor._get_ldap_connection())
到目前为止,一切顺利。但是当我执行单元测试(通过nose)test\u提取器时,从assertRaises语句调用了\u get\u ldap\u connection()
,但是没有捕获异常,测试失败
以下是输出:
vagrant@precise64:/vagrant/sakai-directory-integration$ nosetests

救救我 不调用,只传递函数(方法)本身;放下

或者,如果您使用的是最新版本的python(python 2.7+/python 3.1+),则可以将与self.assertRaises(…)
表单一起使用:
您没有正确使用
assertRaises
您可以将其用作上下文管理器:
with self.assertRaises(ldap.SERVER_DOWN):
test_extractor._get_ldap_connection()
或者通常的方式(self.assertRaises(异常、函数、参数)
:
另见:
self.assertRaises(ldap.SERVER_DOWN, test_extractor._get_ldap_connection)
