[dpdk-dev] [Bug 826] red_autotest random failures

[Danilewicz, MarcinX]

Hi Brandon,

Sorry for late response, but I was busy in mean time. But after your mail well .. I've tried to run test dpdk from docker image. Few instances of images in parallel, enough to get machine fully loaded. But in turn, red_autotest never failed. 

Is it possible for you to share some additional details? About hardware used for testing, memory sizes, etc. To get some hint how to get these failures. I've seen other test failing constantly, depending on machine I was running other autotests. Maybe tests before red_autotest are changing hardware to the state where red_autotest is failing. Anyone tried to change autotests execution order? 

Also, I've don’t almost all to reproduce error and perhaps it is better to ignore that random error for now. It looks like you are able to successfully pass that test all the time, even when is failing from time to time. Right? If that is the true error, it will come out elsewhere.


Kind Regards,
/Marcin

Hi Marcin,

Sorry about that. You can probably remove that line from the Dockerfile. It is used to copy short bash scripts that run meson/ninja with DPDK.
For unit testing, we run a small bash script like this:

#!/bin/bash
tar xzfm dpdk.tar.gz
cd dpdk
meson build --werror
ninja -C build install
cd build
meson test --suite fast-tests -t 60

Thanks,
Brandon
