Global variables in Karma test runner

I have a global variable defined in my main template, which I use to store information bits from the back end, such as the environment context path. I can’t move that variable inside a service.

How can I expose that variable to Karma when I run the unit tests?

Answer

You either declare that global variable within your test file:

var global = "something";

describe('Your test suit', function() {
...
});

or add a Javascript file where it’s defined to your karma.conf.js file:

// list of files / patterns to load in the browser
files: [
   ...,
   'file-containing-the-global-variable.js'
],
