#check ⇒ Boolean

Check if the profile is internall well-structured. The logger will be used to print information on errors and warnings which are found.

Returns:

  • (Boolean) —

    true if no errors were found, false otherwise

#generate_lockfile(vendor_path = nil) ⇒ Inspec::Lockfile

Generate an in-memory lockfile. This won’t render the lock file to disk, it must be explicitly written to disk by the caller.

Parameters:

  • vendor_path (String) (defaults to: nil) —

    Path to the on-disk vendor dir

Returns:
