I have been known to leave tests unattended but only with some pretty extraordinary protections in place. Hardware based interlocking systems with supervisory features. I used to get inspired by looking around elevator control rooms. All relay based controls in those days.
As for data collection, it is useful to have software like the Agilent/Keysight Benchlink or customized Labview apps. There is one test I must do that takes 168 hours. To be certain, I would not leave a test unattended unless it was a benign test or the building had security people around and they know where the EMO switch is located. I have also considered getting a cheap IP-ready bullet camera just so I can periodically monitor the test from a smart phone.

And choose to not live at work for the 15 day tests required for some of the over-loads that must be done on employer's stuff.

One-half hour to set up, seven hours to test, and one-half hour to record results and take down. Eight-hour day. Works for most equipment. For small equipment, it is a long test. For large equipment (intended for long-term operation), it may be too short. And, the equipment should not be unattended during the test as unanticipated failures can occur.
