karma-reporter 
A plugin for running ClojureScript tests with Karma.
Installation
The easiest way is to keep karma-reporter as a dependency in your project.clj:
To be able to execute your ClojureScript tests with Karma, you have to install karma-cljs-test adapter. You can simply do it by:
npm install karma-cljs-test --save-dev
And of course, you need Karma. If you haven't installed it yet, follow these instructions.
Configuration
// karma.conf.js
module.exports = function(config) {
var root = 'target/public/dev'// same as :output-dir
config.set({
frameworks: ['cljs-test'],
files: [
root + '/goog/base.js',
root + '/cljs_deps.js',
root + '/app.js',// same as :output-to
{pattern: root + '/*.js', included: false},
{pattern: root + '/**/*.js', included: false}
],
client: {
// main function
args: ['app.test_runner.run']
},
// singleRun set to false does not work!
singleRun: true
})
}Usage
(ns app.test-runner
(:require [jx.reporter.karma :refer-macros [run-tests run-all-tests]]
[foo.bar-test]))
(enable-console-print!)
; runs all tests in all namespaces
(defn ^:export run-all [karma]
(run-all-tests karma))
; runs all tests in all namespaces - only namespaces with names matching
; the regular expression will be tested
(defn ^:export run-all-regex [karma]
(run-all-tests karma #".*-test$"))
; runs all tests in the given namespaces
(defn ^:export run [karma]
(run-tests karma 'foo.bar-test))To execute tests from command line:
./node_modules/.bin/karma startTo execute tests from REPL (will use :cljs.test/default reporter):
(app.test-runner/run nil)
