The setup and teardown example of Python automation test _python

This article describes the Python Automation test setup and teardown usage, share for everyone to reference. Specifically as follows:

The instance code is as follows:

Class Romannumeralconverter (object): 
  def __init__ (self): 
    Self.digit_map = {"M": 1000, "D": +, "C": 50, "L": , "X": Ten,  
             "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 ()

The output results are as follows:

Create a new Romannumeralconvertertest
..... Destroying a romannumeralconvertertest
..... ----------------------------------------------------------------------
Ran 1 Test in 0.016s

OK

Note: Setup and teardown are invoked when each test method is run
