(defn request ([url]) ([params url])) (s/fdef request :args (s/cat :params (s/? map?) :url string?)) (instrument `request) (request [] "") ExceptionInfo Call to #'user/request did not conform to spec: In: [0] val: [] fails at: [:args :url] predicate: string? :clojure.spec/args ([] "") :clojure.spec/failure :instrument :clojure.spec.test/caller {:file "form-init1226863901212006294.clj", :line 1, :var-scope user/eval2193} clojure.core/ex-info (core.clj:4725) I expected that it would fail at `map?` predicate rather than at `string?` predicate. s/or produces better explanation, but at the same time is relatively more verbose: (require '[clojure.spec :as s]) (require '[clojure.spec.test :refer [instrument]]) (defn request ([url]) ([params url])) (s/fdef request :args (s/or :simple (s/cat :url string?) :advanced (s/cat :params map? :url string?)))
