AngularJS Essentials

After this, you can use the Node Package Manager, also known as npm. It will
manage the installation of everything that we need to set up our environment,
as follows:
npm install –g karma

Configuration
The configuration is quite simple. It just requires a file called karma.conf.js,
located in the root application directory. The best way to create it is by following the
configuration wizard through the following command:
karma init
Karma's configurator will be shown, and you just have to follow the instructions in
order to generate your configuration file.
The first question will be regarding the testing framework you would like to use.
Karma supports Mocha and QUnit beyond Jasmine. After that, it will ask you about
RequireJS, adding it depending on our answer. Then, you will be asked a question
about which browser you want to use. There are many options such as Chrome,
Firefox, Opera, Safari, IE, and even PhantomJS.
Take care of the next question about the location of each source and test file. You
should place it in the correct order, otherwise you can have some trouble. For our
application, the best strategy to adopt is to follow the code organization that we
studied in Chapter 1, Getting Started with AngularJS. After this, you could exclude the
files that you don't want to test.
Finally, Karma will ask you about watching the files and running the tests on every
change. It is a very nice feature to enable, bringing with it a very fast feedback
cycle while you are programming. You can also check out the configuration details
generated through Karma's configurator:
karma.conf.js
module.exports = function(config) {
config.set({
basePath: '',
frameworks: ['jasmine'],
files: [
'lib/angular/angular.js',
'lib/angular/angular-mocks.js',
'src/parkingApp.js',
'src/parkingService.js',
