python自動化測試之setUp與tearDown執行個體

本文執行個體講述了python自動化測試之setUp與tearDown的用法，分享給大家供大家參考。具體如下：

執行個體代碼如下：

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()

輸出結果如下：

Create a new RomanNumeralConverterTest.....Destroying a RomanNumeralConverterTest.....----------------------------------------------------------------------Ran 1 test in 0.016sOK

註：setUp和tearDown在每個測試方法運行時被調用
