A question concerning multi-spec : Suppose I have a spec similar to the one given in the clojure spec guide (ie. :event/event), where different events contain a :event/type key. How can I generate sample events of a particular type, for example :event/error events? Or refer to the spec of a particular event somewhere (e.g. in a s/fdef). What I've tried so far: If I replace the spec from the corresponding defmethod call into a s/def definition, I can obtain the generator for it and I get all the fields I expect but the :event/type key will be a random keyword. Another hack was to generate events from :event/event and then use s/and + predicate to only accepts events which have the correct type, but this "lacks elegance" 🙂

I think something like what you describe is how most people are approaching it right now
