You can either implement this as an initial step to an existing project, or build upon the basic project created in the first recipe. You can do this as follows:

Firstly, you need to create a Karma configuration file named karma.conf.js with the following code:

module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],
    files: [
        "lib/angular/angular.js",
        "lib/angular/angular-mocks.js",
        "src/cookbook.js",
        "test/cookbookSpec.js"
    ],
    autoWatch: true,
    browsers: ['Chrome']
  });
};

Once this has been created, you can run the following command:

karma start

As a result of this, you should see that Karma launches the Chrome browser and produces the following in the console window:

Karma requires a configuration file for it to run our AngularJS application tests. Let's step through the configuration options:

The angular.js file is a dependency for angular-mocks.js, therefore angular.js must be declared before angular-mocks.js.

For a more comprehensive list of configuration options, please refer to Karma's configuration file documents at http://karma-runner.github.io/0.12/config/configuration-file.html.

Use a glob pattern for files, as opposed to declaring each file explicitly, by inserting the following code:

files: [
  "lib/angular/angular.js",
  "lib/angular/angular-mocks.js",
  "src/**/*.js",
  "test/**/*.js"
]
