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
