Python Unit Test Automation

Listing 3-16.  test_module10.py
import unittest
class TestClass11(unittest.TestCase):
        def test_case01(self):
                """This is a test method..."""
                print("\nIn test_case01()")
                print(self.id())
                print(self.shortDescription())
The output of Listing 
3-16
 is as follows:
test_case01 (test_module10.TestClass11)
This is a test method... ...
In test_case01()
test_module10.TestClass11.test_case01
This is a test method...
ok

Failing a Test
Many times, you might want to have a method that explicitly fails a test when it’s called. In 
unittest, the fail() method is used for that purpose. Check the code in Listing 
3-17
 as 
an example.
