Question

可以在unnitest框架中扩展setUpClass吗？

定义扩展unnitest.TestCase的Base1，Base1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Base1中的setUpClass和Base2中的setUpClass在Base2中的所有测试用例之前执行，这可能吗？

Answer 1

您必须明确呼叫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，如果您不添加这些类方法，则可以跳过定义它们：

class Base3(Base1):, 
    def test1(self):
        print('test1')

在这种情况下，来自setUpClass的{{1}}和tearDownClass将被隐式调用。
