Manual Testing Strategy

Make sure to stop the agent before running these tests.

Uptime File and Log

delete the uptime file
delete the uptime log
run the check
both timestamps in uptime file should be the same
wait at least downtime_threshold seconds
run the check, wait a few seconds, then run it again
the downtime log should still not exist (because the previous interval had a length of zero)
the timestamps in the uptime file should be a few seconds apart
wait at least downtime_threshold seconds
run the check
both timestamps in uptime file should be the same
the uptime log should now exist and contain the previous contents of the uptime file
run the check, wait a few seconds, then run it again
wait at least downtime_threshold seconds
run the check
the uptime log should now contain two entries
cat the uptime log
add the following entry to the start of the uptime log: 1 2
run the check
cat the uptime log
the uptime log should be as it was before an entry was added manually
delete the uptime file
run the check

delete the uptime file
delete the uptime log
in a VM, configure an agent to run the uptime check
ensure that the uptime check is running by check the uptime file
power off the VM (don't shut it down gracefully)
ensure that the uptime previous uptime information is now in the uptime log, and that the uptime check continues to run
