Clojurians Log v2

I found something unclear in the documentation for test.chuck. I guess it could be a bug but I think it's more likely I'm holding generators wrong. In particular, I'm trying out the checking macro

When I tested this myself---

So the surprising bit is, why does it work fine if I get my generator with (s/gen int?) and fail if I get (what I think is) the same generator via gen/int?

how does it fail?

oh sorry

only saw the first five lines of the snippet

I'm guessing gen/ refers to clojure.spec.gen.alpha or something of that sort

and that this is the inevitable confusion that stems from the fact that spec generally deals with 0-arg functions that return generators

while http://test.ch[eu]ck deals with vanilla generators

try (gen/int)

yep, that did it

i can attempt to fix that doc if you like, though I haven't forked-and-pulled much open source

which doc?

the checking docs are referring to the clojure.test.check.generators namespace

if you used that namespace instead, gen/int would work and (gen/int) wouldn't

I'm looking here: https://github.com/gfredericks/test.chuck/blob/master/src/com/gfredericks/test/chuck/clojure_test.cljc#L108

Mind you I've been working on untangling the differences among: - clojure.test - test.check - test.chuck - test.check.clojure-test - clojure.spec.alpha.test ...so maybe I'm confusing the hammers I should be using

the problem is that there are two different namespaces that you'll see aliased as gen/

one in test.check and one in clojure.spec

the namespace in clojure.spec mostly exists to alias the namespace in test.check

with the added confusion that it has functions that return generators instead of generators

I would alias the clojure.spec namespace as sgen just to keep things straight

so gen/int is the same as (sgen/int)

I see. Do they have different purposes? Or is clojure.spec an alpha because it's absorbing test.check but hasn't fully digested it yet?

the purpose of the spec namespace is to lazily load test.check only when necessary, so you don't need to have it as a production dependency

that's also the reason for the functions-that-return-generators thing

ohhhhh huh, ok

because specs have some use in production code

Thanks--- there's a lot of polysemy going on in the terms test spec gen and check as I try and develop a sensible workflow for spec-driving

it needs a good blog post or something

I may be able to contribute to the beginners' end of the topic. The comments I'm writing to myself may become a post on a repl-to-gen-tests workflow with cognitect/transcriptor and test.chuck

Not gonna touch when a gen is a gen and when a gen is a thunk
