Python automated testing: setUp and tearDown instances, pythonteardown

This article describes how to use setUp and tearDown for python automated testing. The details are as follows:

The instance code is as follows:

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()

The output result is as follows:

Create a new RomanNumeralConverterTest.....Destroying a RomanNumeralConverterTest.....----------------------------------------------------------------------Ran 1 test in 0.016sOK

Note: setUp and tearDown are called when each test method is run.


Roles of SETUP and TEARDOWN in software testing

SETUP and TEARDOWN are two method names in the third-party one-month test API --- XUnit (JUnit). The setup method mainly implements the initialization before the test, and the teardown method mainly implements the garbage collection after the test is complete!
Simple answer:
Setup marks the start of Data initialization for unit test
Teardown mark unit test complete and start to recycle initialization data Spam
