Reproducing tests¶
For every test triggered using tuxsuite, you can reproduce the same test run locally.
TuxTest is using TuxRun for testing the linux kernel on both cloud or local host. In order to use the exact same environment, TuxRun is leveraging podman with custom container images.
Setting up¶
Host dependencies¶
You should install podman and python:
sudo apt install podman
sudo apt install python3 python3-pip
TuxRun¶
You should now install TuxRun from PyPi:
python3 -m pip install --upgrade tuxrun
Reproducing¶
To reproduce 1yDfQuBu7L5Z662qFRla2uuypuu, go to the web page and download the tuxrun_reproducer.sh.
#!/bin/sh
# TuxRun is a command line tool and Python library that provides a way to
# boot and test linux kernels.
#
# TuxRun supports the concept of runtimes. For that to work it requires that
# you install podman or docker on your system.
#
# To install tuxrun on your system globally:
# sudo pip3 install -U tuxrun
#
# See https://tuxrun.org/ for complete documentation.
tuxrun --runtime podman \
--device qemu-armv5 \
--kernel https://storage.tuxboot.com/armv5/zImage \
--image docker.io/lavasoftware/lava-dispatcher:2021.08
--tests ltp-smoke ltp-fcntl-locktests
The output will look like:
