Fixture and fixtures in Python

1 Fixture Concept

Fixture is the concept in testing:

• Fixture refers to data and conditions that are dependent on the test, etc.
• Python's UnitTest library provides some support for fixture
• Each testcase should be responsible for the creation of resources in setup, such as

Class Mytestcase (UnitTest. TestCase):    def my_fixture_setup (self):        pass    def setup (self):        super (Mytestcase, self). Setup ()        Self.my_fixture_setup ()

• Each testcase should create a new function that is responsible for the destruction of resources. and add this new function to TestCase's cleanup list.

Class Mytestcase (UnitTest. TestCase):    def my_fixture_cleanup (self):        print ("++++ my_cleanup")               def setUp (self):        super ( Mytestcase, self). SetUp ()        self.addcleanup (Self.my_fixture_cleanup)

The following is the complete code

From __future__ import Print_functionimport unittest class Mytestcase (unittest. TestCase):    def my_fixture_setup (self):        pass            def my_fixture_cleanup (self):        print ("++++ my_cleanup" )               def setup (self):        super (Mytestcase, self). Setup ()        self.my_fixture_setup ()        Self.addcleanup ( Self.my_fixture_cleanup)    def tearDown (self):        super (Mytestcase, self). TearDown ()        print ("++++ TearDown ")            def My_cleanup (self):        print (" ++++ my_cleanup ")            def test_case_1 (self):        print (" ++++ test Case 1 ")

The fixtures package fixtures (complex number) in Python 2 is a package in Python that provides toolkits for quick creation/destruction of fixture

• The Test case needs to be derived from TestTools. TestCase class
• If you need to customize fixtures, you need to derive from fixtures. Fixture class, and overwrite the Setup/cleanup method of the parent class

An example of a custom fixtures class is as follows

From __future__ import print_functionimport fixturesimport testtoolsclass myfixture (fixtures. Fixture):    def setup (self):        super (Myfixture,self). Setup ()        self.frobnozzle =        print ("++++ Myfixture.setup () ")            def cleanUp (self):        super (Myfixture,self). CleanUp ()        print (" ++++ myfixture.cleanup () ")        print ()           class Mytestcase (TestTools. TestCase):               def setup (self):        super (Mytestcase, self). Setup ()        self.my_fixture = Self.usefixture ( Myfixture ())        print ("++++ setUp")    def TearDown (self):        super (Mytestcase, self). TearDown ()        Print ("++++ TearDown")            def test_case_1 (self):        self.assertequal (self.my_fixture.frobnozzle)        print ("++++ test Case 1")
