• /validate - run terraform validate
• /plan - plan the infrastructure (only examples)
• /apply - deploy the infrastructure and destroy afterwards (only examples)

The 1^st command does not take arguments, the remaining take two:

/idempotence paths="examples/combined_design examples/panorama_standalone" tf_version="1.2 1.4 1.5.4"

# run validation tests with the latest available Terraform version on listed modules.
/validate paths="modules/vmseries modules/vpc examples/combined_design"
