测试除法
1、自动以1个除法函数div
2、测试 1/1
3、测试 3/4
4、测试 3/0
import unittest
def div(a, b):
return a / b
# 1 / 2 = 1
class MyfirstTestCase(unittest.TestCase):
pass
def setUp(self):
print 'run before every testcase'
def tearDown(self):
print 'run after every testcase'
def test_1div1(self):
print 'case1:1/1'
case1 = div(1, 1)
self.assertEqual(case1, 1/1)
def test_3div4(self):
print 'case1:3/4'
case2 = div(3, 4)
self.assertEqual(case2, 3/4)
def test_3div0(self):
print 'case3:3/0'
case3 = div(3, 0)
self.assertRaises(ZeroDivisionError, div, 3, 0)
if __name__ == '__main__':
unittest.main()
