setUpClass是否可以在最不合理的框架中扩展?
定义扩展unnitest.TestCase的Base1,Base1具有setUpClass方法。
import unittest
class Base1(unittest.TestCase):
@classmethod
def setUpClass(cls):
print('setupClass - this is Base1')
@classmethod
def tearDownClass(cls):
print('tearDownClass - this is Base1')
定义扩展Base1类的Base2
from Base1 import Base1
import unittest
class Base2(Base1):
@classmethod
def setUpClass(cls):
print('setupClass - this is Base2')
@classmethod
def tearDownClass(cls):
print('tearDownClass - this is Base2')
def test_default_size(self):
self.assertEqual('a','a')
def test_resize(self):
self.assertEqual('a','b')
我希望在Base2中的所有测试用例之前执行Base1中的setUpClass和Base2中的setUpClass,这可能吗?
最佳答案
您必须显式调用setUpClass
和tearDownClass
:
class Base2(Base1):
@classmethod
def setUpClass(cls):
print('setupClass - this is Base2')
super(Base2, cls).setUpClass()
@classmethod
def tearDownClass(cls):
print('tearDownClass - this is Base2')
super(Base2, cls).tearDownClass()
但是,如果不添加这些类方法,则可以跳过对它们的定义:
class Base3(Base1):,
def test1(self):
print('test1')
在这种情况下,
setUpClass
中的tearDownClass
和Base1
将被隐式调用。关于python - setUpClass是否可以在最不合理的框架中扩展?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/37107185/
