CoffeeScript Question

CoffeeScript Code UnitTest AngularJS - Jasmine - Karma

I am trying to write unit test to my Controllers and services of my Ionic project written with CoffeeScript. I chose to use Karma and Jasmine. The problem is it doesn't interpreter coffeeScript. That's why I used this plugin karma-coffee-preprocessor so that it will be possible. I don't know if I am doing it right.

I installed the plugin with the command ;

npm install --save-dev karma-coffee-preprocessor

I then configured my test config file as follows:

module.exports = function(config) {

basePath: '',
frameworks: ['jasmine'],
files: [

exclude: [

preprocessors: {
'../src/scripts/**/*.coffee': ['coffee']

coffeePreprocessor: {
options: {
bare: true,
sourceMap: false
transformPath: function(path) {
return path.replace(/\.coffee$/, '.js')

reporters: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_DEBUG,
autoWatch: true,
browsers: ['PhantomJS'],
singleRun: false,
concurrency: Infinity

But when I try to start my test I have this error :

Can not load "coffee", it is not registered!
Perhaps you are missing some plugin?
throw error('No provider for "' + name + '"!');

Error: No provider for "framework:jasmine"! (Resolving: framework:jasmine)

Can anyone help me ?
I having trouble making these unit tests, and I don't know if I am doing things the right way.


First of all you need to install jasmine framework via npm and add it to the frameworks collection in karma config file:

$ npm install karma-jasmine --save-dev

then add:

frameworks: ['jasmine']

to karma config file.
