Hi,
So I looked at generating specs for tests and I hit an error I just dont
understand / neither can fix it. This is my code:
(s/def ::column-types #{:int :varchar :boolean :text :time :date
:char :binary :smallint :bigint :decimal
:float :double :real :timestamp})
(s/def ::name (s/and string? #(not= "" %)))
(s/def ::boolean (s/or :t true? :f false?))
(s/def ::type ::column-types)
(s/def ::null ::boolean)
(s/def ::max-length (s/and integer? #(< 0 %)))
(s/def ::required ::boolean)
(s/def ::pk ::boolean)
(s/def ::autoinc ::boolean)
(s/def ::unique ::boolean)
(s/def ::default (s/or :string string? :boolean ::boolean))
(s/def ::refs ::none-empty-string)
(s/def ::fk-name ::none-empty-string)
(s/def ::column (s/keys :req-un [::name ::type]
:opt-un [::null ::max-length ::required ::pk
::autoinc ::unique ::default
::refs ::fk-name]))
(s/def ::columns (s/cat :column (s/+ ::column)))
;function
(s/fdef remove-autoinc-columns :args (s/cat :cols (s/spec columns))
:ret ::schem/columns)
(defn remove-autoinc-columns [cols]
(vec (remove #(= true (:autoinc %)) cols)))
; generative test
(defspec remove-autoinc-column 100
(prop/for-all [columns (s/gen ::schem/columns)]
(= (h/remove-autoinc-columns columns))))
; will fail with something along the lines of:
ERROR in (remove-autoinc-column) (core.clj:4617)
Uncaught exception, not in assertion.
expected: nil
actual: clojure.lang.ExceptionInfo: Call to
#'de.sveri.clospcrud.helper/remove-autoinc-columns did not conform to spec:
val: () fails spec: :de.sveri.clospcrud.spec.clospcrud/columns at: [:ret
:column] predicate: :de.sveri.clospcrud.spec.clospcrud/column,
Insufficient input
:clojure.spec/args (({:name "QpJ50qrS1m24V", :type :varchar, :unique true,
:required false, :autoinc true, :null true, :pk true, :max-length 14,
:fk-name "Tp9tG8hwUXK0"}))
I cannot see where the error is coming from, I generate data according to a
spec which I pass to a function that takes this spec exactly.
Any ideas?
Thanks,
Sven
