cljasmine

A ClojureScript BDD testing framework based on Jasmine that displays your test results in a browser page and comes with auto-refresh.

Syntax

(ns my.test.ns
  (:require-macros [cljasmine.macros :as j])
  (:require [cljasmine.checkers]))

(j/describe "The value true"
  (j/it "should be true"
    (j/expect true := true))
  (j/it "should not be false"
    (j/expect true :not= false)))

Current Limitations

  • When changing a file in your source folder, you won't see any changes in your browser until you touch a file in your test folder. That is because we haven't yet found a way to make lein cljsbuild auto do what we want (see lein-cljsbuild issue 159)
  • Hasn't yet been tested with advanced compilation - but this can't be too hard either..

Requirements

Trying it out

  • Clone this repository and cd into it.
  • Do bundle install.
  • Do foreman start.
  • You might get a TSP server error: Address already in use. Not sure how this happens, but it will work anyways oO
  • Point your browser to http://localhost:8888. You should see a few passing specs now.
  • Enable the LiveReload plugin now, if you installed it.
  • Open test/cljasmine/core_test.cljs in an editor of your choice.
  • Try to break one of the test cases (for example by replacing one :< by :>).
  • Save the file
  • After a few seconds, you'll see the failure in your browser. Without LiveReload, you'll need to hit refresh.

Setup for your own project

  • Do lein install in the cljasmine directory.
  • Copy over the following stuff to your own project directory:
    • The spec directory.
    • Gemfile, Rakefile, Procfile, and Guardfile.
  • Configure lein-cljsbuild in your project.clj similar to cljasmine's own project file. If you want to change the path of unit-test.js, you'll need to adjust spec/javascripts/support/jasmine.yml accordingly.
  • Start writing tests and do the same as above.

Your own checkers

(j/defchecker :has-key [result key]
  (when-not (get result key)
    ["Actual result:" result
     "doesn't contain the key:" key]))

You may also return a string or a keyword for the error message. Now, you can write:

(j/describe "The map {:a 1}"
  (j/it "contains the key :a"
    (j/expect {:a 1} :has-key :a)))

If you define the checker in another namespace, remember to require it from the tests.

Awesome idea!
