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 0.016s

OK

 

注：setUp和tearDown在每个测试方法运行时被调用
