doesnt-kill-you-makes-you-stronger/endurance/
Tests typically done to find out whether device(s) under test can withstand the processing load for extended
periods of time. During endurance tests, metrics such as CPU, memory consumption is observed to determine
potential failures. Clients (managed and unmanaged) resiliency during reboots and power save modes.
Performance quality is key KPI monitored during endurance testing.
