本文实例讲述了python自动化测试之连接几组测试包的方法，分享给大家供大家参考。具体方法如下：

具体代码如下：   
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):
    self.cvt = RomanNumeralConverter()
      
  def test_parsing_millenia(self):
    self.assertEquals(1000, self.cvt.convert_to_decimal("M"))
      
  def test_parsing_century(self):
    self.assertEquals(100, self.cvt.convert_to_decimal("C"))
      
class RomanNumeralConverterCombo(unittest.TestCase):
  def setUp(self):
    self.cvt = RomanNumeralConverter()
      
  def test_multi_millenia(self):
    self.assertEquals(4000, self.cvt.convert_to_decimal("MMMM"))
      
  def test_add_up(self):
    self.assertEquals(2010, self.cvt.convert_to_decimal("MMX"))
      
if __name__ == "__main__":
  suite1 = unittest.TestLoader().loadTestsFromTestCase(RomanNumeralConverterTest)
  suite2 = unittest.TestLoader().loadTestsFromTestCase(RomanNumeralConverterCombo)
  suite = unittest.TestSuite([suite1, suite2])
  unittest.TextTestRunner(verbosity=2).run(suite)

运行结果如下：   
test_parsing_century (__main__.RomanNumeralConverterTest) ... ok
test_parsing_millenia (__main__.RomanNumeralConverterTest) ... ok
test_add_up (__main__.RomanNumeralConverterCombo) ... ok
test_multi_millenia (__main__.RomanNumeralConverterCombo) ... ok

----------------------------------------------------------------------
Ran 4 tests in 0.032s

OK

本文实例与前面几篇文章的内容基本一致，只在main中有些不同：
suite1 = unittest.TestLoader().loadTestsFromTestCase(RomanNumeralConverterTest)
  suite2 = unittest.TestLoader().loadTestsFromTestCase(RomanNumeralConverterCombo)
  suite = unittest.TestSuite([suite1, suite2])
  unittest.TextTestRunner(verbosity=2).run(suite)
希望本文所述对大家的Python程序设计有所帮助。
