我想为以下代码编写一些测试:
def person_name_length(id):
person = get_person(id)
return len(person.first_name)
如何模拟get_person(id)
方法,使其返回一个具有first_name
属性值的对象?
在代码中:
@patch('get_person')
def test_person_name_length(self, get_person_mock):
get_person_mock.return_value = # what goes here??? calling .first_name on it should return 'Bob'
self.assertEqual(person_name_length(1), 3)
答案 0 :(得分:1)
我认为你应该做这样的事情
class MockPersion(object):
first_name = 'Bob'
@patch('get_person')
def test_person_name_length(self, get_person_mock):
get_person_mock.return_value = MockPersion()
self.assertEqual(person_name_length(1), 3)
