Alternative to conftest

[Iristyle]

Looks like it might be possible to use this as an alternative to the conftest tool? Have you considered the possibility?

I really like the idea of being able to interactively debug the rego tests (which conftest does not support since it doesn't have a REPL). I'm not sure what might be necessary to make that happen, but I think at the very least, data loading at #205 seems necessary.

That sounds like a great idea. I don't think fregot should be a full alternative to conftest but it definitely should be able to help debugging tests. I'll see if there's any further glue I need to add to make fregot understand the conftest conventions.

@Iristyle So I had a try with this. I create policy/deployment.rego which has a main package with deny specified. I also created deployment.yaml. I started fregot using:

fregot repl --watch --input deployment.yaml policy/

And was then able to start debugging the conftest policies using:

:break main.deny
data[_].deny

Does that suffice for your use case? I'm not sure how we can make this more convenient -- should we have a conftest helper that runs all deny statements? For simple debugging, it just seems to work. Could you give this a try and see what is missing?
