Executing tests in the CLI - Manual - AxUnit-ST - AxUnit ST documentation package - AxUnit-ST,

The default engine for testing is LLVM.

  apax test

If you want to execute tests for a different target, you must specify this with the additional engine parameter -e and the target IP address:

-e plcsim or -e mc7p and -t "127.0.0.1"

You may add the target IP variable to the apax.yml file, and add it as a variable to your CLI call:

variables:
  AXUNIT_TARGET_IP: "192.168.0.1"

apax test -e plcsim -t $AXUNIT_TARGET_IP
