本文实例讲述了python自动化测试之setup与teardown的用法，分享给大家供大家参考。具体如下：
实例代码如下：
class RomanNumeralConverter(object):
def __init__(self):
self.digit_map = {"M":1000, "D":500, "C":100, "L":50, "X":10,
"V":5, "I":1}
def convert_to_decimal(self, roman_numeral):
val = 0
for char in roman_numeral:
val += self.digit_map[char]
return val
import unittest
class RomanNumeralConverterTest(unittest.TestCase):
def setUp(self):
print "Create a new RomanNumeralConverterTest....."
self.cvt = RomanNumeralConverter()
def tearDown(self):
print "Destroying a RomanNumeralConverterTest...."
self.cvt = None
def test_parsing_millenia(self):
self.assertEquals(1000, self.cvt.convert_to_decimal("M"))
if __name__ == "__main__":
unittest.main()输出结果如下：
Create a new RomanNumeralConverterTest..... Destroying a RomanNumeralConverterTest.... . ---------------------------------------------------------------------- Ran 1 test in 0.016s OK
注：setUp和tearDown在每个测试方法运行时被调用
