python自动化测试之setUp与tearDown实例

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 0.016sOK

注：setUp和tearDown在每个测试方法运行时被调用
