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....
.

ok

注：setup和teardown在每个测试方法运行时被调用
