    @bhaisaab, we've looked into the code of that test, and the results are unreliable.
    The steps that are done in that test (along with the implementation of the called method)
    1. Create file
    2. Register start time
    3. Loop until the diff between now and last modified or last accessed time is higher than
a passed threshold (2000ms)
    4. Register end time
    5. Check if diff between start and end time is lower than passed threshold (2000ms)
    
    It's possible that between step 1 and 2, mostly on a loaded system, the thread that is
running the test has to wait for available resources on your system. Therefore it's possible
that step 3 returns immediately without looping. So, the end time will be really close to
the start time, and will be below those 2000ms.
