Re: [ANN] prismatic/schema 1.0 adds automatic test data generation
It works great. All I did was updated project.clj, replaced s/both with s/constrained and removed the s/pred around the arguments, and it all worked. One little weird thing: It now complains: WARNING: atom already refers to: #'clojure.core/atom in namespace: schema.core, being replaced by: #'schema.core/atom But I can't figure out why, because schema.core is clearly excluding atom. This project is on clojure 1.7.0. -Jason On Mon, Oct 26, 2015 at 11:58 AM, Jason Felice wrote: > Thanks! > > I'll try it out this week and let you know. > > On Sun, Oct 25, 2015 at 8:28 PM, Jason Wolfe wrote: > >> FYI -- we just released Schema 1.0.2, which adds `s/constrained` for >> postconditions. >> >> -Jason >> >> On Thursday, September 3, 2015 at 3:05:29 PM UTC-3, Jason Felice wrote: >>> >>> >>> On Wed, Sep 2, 2015 at 9:56 PM, Jason Wolfe wrote: Outside of that, I can still potentially see the desire to specify postconditions rather than preconditions (you'd rather see an error (not (integer?

Re: [ANN] prismatic/schema 1.0 adds automatic test data generation
Hi Jason, That's a great question, thanks. The exception you point out is just a bug: https://github.com/Prismatic/schema/issues/263. Preconditions currently wrap exceptions and return sensible validation errors, we just missed this in guards. Will address this ASAP and cut a new release. Outside of that, I can still potentially see the desire to specify postconditions rather than preconditions (you'd rather see an error (not (integer? "1")) than (throws? (odd? "1")), which will be the behavior when the bug is fixed. We're thinking about whether it's worth the extra complexity to support that, what are your thoughts? If you think it would be valuable, please open another issue on github so we can track it -- thanks. As for your solution (s/conditional number? (s/pred pos?)), that will also work fine, and you can still use the generator support -- you will just have to pass in a leaf generator for your schema (although this admittedly isn't ideal).

Re: [ANN] prismatic/schema 1.0 adds automatic test data generation
I have a question: "both" is deprecated with a note to use "s/conditional" instead. However, that doesn't work for my case. I have the following: (s/both s/Int (s/pred pos?)) If I rewrite it to (s/conditional pos? s/Int), this throws: (s/check (s/conditional pos? s/Int) "") Since (as far as I can tell), I can't verify the type is numeric before applying pos? I could do this: (s/conditional number? (s/pred pos?)), but I'm going to guess this will defeat test.check support, which I'd like to use. Thoughts?
