Stress Testing for new HDDs?

[user]

I have heard people mentioning that a HDD will fail either at the beginning or at the end of its life cycle, therefore a stress test should be done on all new HDDs before use.

1. Is it recommended to do a stress test for new HDDs before putting it to use in a NAS?
2. How can I do a stress test? Any software needed? How long will it take? Step by step and alternative methods are appreciated.
3. Can I do it on the NAS itself? This is because I do not own an adapter and power supply for a 3.5" HDD.
4. If #3 is possible, can it be done for the second and subsequent drives on the NAS itself while keeping its RAID configuration? Same reason because I do not own an adapter and power supply.

Thanks and appreciate all responses!
