binding => var-symbol temp-value-expr
Temporarily redefines vars while executing the body. The temp-value-exprs will be evaluated and each resulting value will replace in parallel the root value of its var. After the body is executed, the root values of all the vars will be set back to their old values. Useful for mocking out functions during testing.
Usage:
(with-reset [http/get (fn [url] :test)]
(is (= (http/get :url) :test)))
