Does it mean the box survived the test?

Yes, please.

Before 2. in your procedure run 'echo core > /sys/power/pm_test'.  It will not
hibernate then, but it'll run the hibernation sequence including suspending
devices etc.  Next, it'll wait for 5 seconds and run the resume sequence.

Please let me know if the box(es) work(s) correctly after that.

Best,
Rafael
