Python Unit Test Automation

Listing 3-2.  test_module02.py
import unittest
import inspect
class TestClass02(unittest.TestCase):
        def test_case02(self):
                print("\nRunning Test Method : " + inspect.stack()[0][3])
        def test_case01(self):
                print("\nRunning Test Method : " + inspect.stack()[0][3])
if __name__ == '__main__':
        unittest.main(verbosity=2)
In the code in Listing 
3-2
, inspect.stack()[0][3] method prints the name of the 
current test method. It’s useful for debugging when you want to know the order that the 
methods are executed in the test class. The output of the code in Listing 
3-2
 is as follows:
test_case01 (__main__.TestClass02) ...
Running Test Method : test_case01
ok
test_case02 (__main__.TestClass02) ...
Running Test Method : test_case02
ok
----------------------------------------------------------------------
Ran 2 tests in 0.090s
OK
Note that the test methods ran in alphabetical order, irrespective of the order of the 
test methods in the code.

Verbosity Control
In earlier examples, you controlled the verbosity of test execution through the command 
while invoking the Python test script in the OS console. Now, you will learn how to control 
the verbose mode from the code itself. See the code in Listing 
3-3
 for an example.
