unittest单元测试框架之测试环境的初始化与还原（fixture）
（五）
1.⽅法⼀：针对每条测试⽤例进⾏初始化与还原
import unittest
from UnittestDemo.mathfunc import *class TestMathFunc(unittest.TestCase): \"\"\"测试 mathfunc.py\"\"\"
# 在每条测试⽤例执⾏之前准备好测试环境 def setUp(self):
print(\"do something before test!\")
# 在每条测试⽤例执⾏结束之后准备好测试环境 def tearDown(self):
print(\"do something after test!\") def test_add(self):
\"\"\"测试加法 add()\"\"\"
self.assertEqual(3,add(1,2)) self.assertNotEqual(3,add(2,2)) def test_minus(self):
\"\"\"测试减法 minus\"\"\"
self.assertEqual(1,minus(3,2)) def test_multi(self):
\"\"\"测试乘法 multi\"\"\"
self.assertEqual(6,multi(2,3)) def test_divide(self):
\"\"\"测试除法 divide\"\"\"
self.assertEqual(2,divide(6,3))
self.assertEqual(2,divide(5,2))
2.⽅法⼆：1.⽅法⼀：针对每条测试⽤例进⾏初始化与还原
import unittest
from UnittestDemo.mathfunc import *class TestMathFunc(unittest.TestCase): \"\"\"测试 mathfunc.py\"\"\" @classmethod def setUpClass(cls):
print(\"do something before testClass,only run once!\") @classmethod
def tearDownClass(cls):
print(\"do something after testClass,only run once!\") def test_add(self):
\"\"\"测试加法 add()\"\"\"
self.assertEqual(3,add(1,2)) self.assertNotEqual(3,add(2,2)) def test_minus(self):
\"\"\"测试减法 minus\"\"\"
self.assertEqual(1,minus(3,2)) def test_multi(self):
\"\"\"测试乘法 multi\"\"\"
self.assertEqual(6,multi(2,3)) def test_divide(self):
\"\"\"测试除法 divide\"\"\"
self.assertEqual(2,divide(6,3))
self.assertEqual(2,divide(5,2))
