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
