Configuration: Bindings

You can configure dynamic vars from tests.edn, these will be bound to the given values during the complete loading and running of the tests.

Technically they are bound after the config step, so config hooks will not see the given values, while pre-load up to post-run will.

The :bindings configuration key takes a map from var name to value.

Some suggestions of things you can do with this:

  • kaocha.stacktrace/*stacktrace-filters* [] disable filtering of stacktraces, showing all stack frames
  • clojure.pprint/*print-right-margin* 120 Make pretty printing use longer line lengths
  • clojure.test.check.clojure-test/*report-completion* false, clojure.test.check.clojure-test/*report-trials* false Make test.check less noisy.

Binding dynamic vars

  • Given a file named "tests.edn" with:
#kaocha/v1
{:bindings {my.foo-test/*a-var* 456}}
  • And a file named "test/my/foo_test.clj" with:
(ns my.foo-test
  (:require [clojure.test :refer :all]))

(def ^:dynamic *a-var* 123)

(deftest var-test
  (is (= 456 *a-var*)))
  • When I run bin/kaocha

  • Then the output should contain:

1 tests, 1 assertions, 0 failures.
