The unit test process in Python

The unit test process in Python

Looked at the unit test flow in Python, wrote a test code to see the overall testing process

Summarized as follows

• A test case class should derive from UnitTest. TestCase
• The normal test case is called in the order

• Subclass TestCase can register its own cleanup function (My_cleanup). This cleanup function will be called after teardown

    def setup (self):        super (Mytestcase, self). Setup ()        self.addcleanup (Self.my_cleanup)

• Unit test function Name must start with "Test_"

    def test_case_1 (self):        print ("++++ test Case 1")

Test the source code:

From __future__ import print_functionimport unittestdef setupmodule ():    print ("Setupmodule") def teardownmodule ():    print ("Teardownmodule")    class Mytestcase (unittest. TestCase):    def setup (self):        super (Mytestcase, self). Setup ()        self.addcleanup (self.my_cleanup)                Print ()        print ("++++ setup")    def TearDown (self):        super (Mytestcase, self). TearDown ()        print ("++++ TearDown ")        raise Exception ()            def my_cleanup (self):        print (" ++++ my_cleanup ")            def test_case_1 ( Self):        print (' ++++ test Case 1 ')    def test_case_2 (self):        print ("++++ test Case 2")              @classmethod    def setupclass (CLS):        print ("SetupClass")    @classmethod    def teardownclass (CLS):        print ()        print ("Teardownclass")

The running result of this program:
