a minimalist's unit testing framework
This project is maintained by seancorfield and jaycfields
adding signal, removing noise
this is documentation for the "classic" expectations library (considered stable and "in maintenance mode" at this point). it uses its own set of tooling and is not compatible with clojure.test-based tooling. there is a very actively-maintained variant of expectations that is compatible with clojure.test and its tooling: expectations.clojure.test (see also clojure.test compatibility)
;; expectations uses the format (expect expected actual) for all tests
;; (equality, expected exception, regex matching, interactions, etc).
;; use expectations to test equality
(expect 1 1)
(expect "foo" "foo")
;; test if the regex is in a string
(expect #"foo" "boofooar")
;; does the form throw an expected exception
(expect ArithmeticException (/ 12 0))
;; expect a value in a collection (k/v for maps)
(expect {:foo 1} (in {:foo 1 :cat 4}))
(expect :foo (in #{:foo :bar}))
(expect :foo (in [:bar :foo]))
;; expect a function to return a truthy value given the actual argument
(expect empty? (list))
consistent syntax is very important to expectations, but there are additional features that focus on increasing signal and reducing noise.
expectations is simple to get started with, but also very feature rich. Please click Introduction to begin exploring it's many features
