Hi List,
I'm trying to make a reg-test to verify some behavior for
server-state-file..
But i cant figure out why it fails at random places if ran like 10 times
in a row, can someone provide a clue? I've tried playing with 'delay
0.1' settings in between commands.. but that doesn't fix all..
Ive ran it against "HA-Proxy version 1.9-dev1-26e1a8f 2018/09/12"..
varnishtest -l -n 10 -t 5 -k ./seamless-reload/b00001-state.vtc
Any of the following error might pop up if ran like 30 times in a row..
---- h1 0.4 CLI expect failed ~ "1 srv1 127.0.0.1 2"
---- h1 0.4 CLI expect failed ~ "2 srv2 127.0.0.3 0"
---- c5 0.4 EXPECT resp.status (503) == "200" failed
---- c6 0.5 EXPECT resp.status (200) == "503" failed
Above errors appear randomly.. sometimes 9 out of 10 tests pass
sometimes less..
---- h1 0.9 CLI expect failed ~ " - 33 -" << The port change not
being picked up is a 'known bug' afaik.
Am i writing the test in a wrong way? Should i wait/lock/check something
after some steps and if so how?
Also its taking like a second or more to complete. is there a way to
make it faster, without loosing predictability?
Regards,
PiBa-NL (Pieter)
