# axx validate

> Check feature files without running them: syntax, undefined and ambiguous steps

Source: https://axx.nimbusxr.us/references/cli/axx-validate/

Parse feature files and match every step against the available step
definitions, without starting applications or executing anything.

Also prints the warnings of axx lint's feature checks (SQL selection and
trigger ordinals that cannot work); they do not change the exit code.

Exit codes: 0 valid, 2 syntax/config error, 3 undefined or ambiguous steps.
