Testing:Process

Make sure you have verbose logging, usually called "debug mode" when doing any type of testing. Make sure you are watching the logs in real time.

tail -f /var/log/messages

is a common example to have running in an unused terminal.

Try examples that should return both positive and negative results and see how it affects the logs. Try as many different approaches as possible with your examples, so you catch any potential errors.

Once you're done, turn your logging back to a regular level (turn off debud mode) and continue to watch and make sure and everything seems to be running as expected.
