Running regression

In case you did some changes in code and/or want to check some new NIC, you can run our regression:

  1. Create TRex config file: sudo ./dpdk_setup_ports.py -i

  2. Run TRex daemon: sudo ./trex_daemon_server start

  3. Make a copy of directory with setup parameters: automation/regression/setups/trex07

  4. Update yaml files in that directory if needed

  5. Run full regression:
    ./run_regression --cfg ./automation/regression/setups/<new dir>

Note

  • Running specific test:
    ./run_regression --cfg ./automation/regression/setups/<new dir> -t <part of test name>

  • Running only stateless tests can be done without waiting for TRex server to be brought up each time:

    • Run in one shell the interactive server: sudo ./t-rex-64 -i

    • Run in another shell the regression with flags: --stl --no-daemon

  • Specifying setup directory can be done only once with environment variable SETUP_DIR, for example:
    export SETUP_DIR=trex07
