1. CHANGE OF SCOPE NOTICE

BREAKING CHANGES as of 3.1. The =throws⇒ clause now just takes either a type or a regex. Not maps/lists.

BREAKING CHANGES as of 3.0. Do NOT upgrade without being prepared to port your test runners.

❗️	This library no longer contains browser-based runners.

I recommend the following alternatives:

Clojure Tests: I recommend IntelliJ/Emacs/Vim in-editor testing, or perhaps Clojure Tools Deps with kaocha. The latter renders into a terminal, but can use fulcro-spec’s macros. Here is a sample config file that will use Fulcro spec’s terminal reporting:

#kaocha/v1
    {:tests    [{:id           :unit
                 :ns-patterns  ["-test$" "-spec$"]
                 :test-paths   ["src/test"]
                 :skip-meta    [:integration]
                 :source-paths ["src/main"]}]
     :reporter [fulcro-spec.reporters.terminal/fulcro-report]
     :plugins  [:kaocha.plugin/randomize
                :kaocha.plugin/filter
                :kaocha.plugin/capture-output]}

Clojurescript Tests: I highly recommend using Nubank’s Workspaces. I’ve contributed a shadow-cljs target that can auto-scan for tests if you use their deftest macro. Again, things like the provided macro work within Workspaces. I recommend using shadow-cljs :karma target for running CI tests.

See the docs for more details.

2. Description

A Clojure(scipt) testing library to augment the standard clojure.test.

Release: Snapshot:

It is common to want to run tests in the REPL, but the output of the default runner leaves a lot to be desired. If you’re using IntelliJ you can now add something like this to your REPL commands (and hook it to a keyboard shortcut) for a much better testing experience:

Run Tests with a :focus metadata marker (selector):

(require 'fulcro-spec.reporters.repl)
(in-ns '~file-namespace)  ; if using in an IntelliJ REPL Command
(fulcro-spec.reporters.repl/run-tests #(:focus (meta %)))

Run all tests:

(require 'fulcro-spec.reporters.repl)
(in-ns '~file-namespace)  ; if using in an IntelliJ REPL Command
(fulcro-spec.reporters.repl/run-tests)

ℹ️	Be sure to check "Before Executing" → "Load File" on the REPL command.

4. Usage

(ns my-test
  (:require
    [fulcro-spec.core :refer [when-mocking provided assertions]
    [clojure.test :refer [deftest]]
    ...))

(defn f [x] 900)
(defn g [y] (f y))

(deftest my-test
  (when-mocking
    (f x) => 22

    (assertions
      "mocking works"
      (g 9) => 31)))
