I think I got some more idea about the issue though I still don't know the root cause.
So, my test program is importing design file.
Both test and design file are have the following lines:
#Create and configure logger
filename = os.path.join(os.path.dirname(os.path.realpath(__file__)), 'test_5.log')
logging.basicConfig(filename=filename, filemode='w', format='%(asctime)s %(message)s')
#Creating an object
logger = logging.getLogger()

I think this is causing the issue. Anyway, I am able to log from the test program. However, I am not able to log anything from design program.

I will open a separate thread on this topic.
