A simple test for memory leaks is to leave the system running after the last test of the day; if the system has recovered to the original state by the next day, then you can often rule out a leak.

For example, a tester can use the hardware one day to test on a specific operating system version and quickly swap out to run a different operating system version the next day.

You might find this output to be rather verbose; you can modify the test framework to be more terse for day-to-day use.
