Testing Regula advanced rules?

[Christophe Tafani-Dereeper]

Hello,

Is it possible to use fregot test to run unit tests of Regula advanced rules making use of fugue.resources, fugue.deny_resource and similar functions?

So far, simply running fregot test raises errors because it's not aware of the definition of these functions:

$ frego test rules/aws_s3_bucket_public_access_block.rego
 "rules/aws_s3_bucket_public_access_block.rego" (line 12, column 11):
  unknown call:

    12| buckets = fugue.resources("AWS.S3.Bucket")
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Unknown call to fugue.resources

...

Thanks!

Right -- fregot needs to be aware of the definitions to run them. You can pass multiple files and/or directories to fregot test, so you can try something like: fregot test lib rules tests examples (or anything more fine-tuned as well). But since Regula tests require a little bit of set up, I would start by copying some existing tests in the Regula repository and then go from there.
