Constants in Jasmine unit tests

provide_constant.js

describe('Test', function() {

  beforeEach(function() {
    module('App', function($provide) {
      $provide.constant('CSRF_TOKEN', 'MOCK_CONSTANT'); // <= mock your constant
    });
  });

  // Tests go here

});

Great for $httpBackend tests, as it lets you test if $http requestst use env / constants / config

How do you use that constant value in your specs?

This helped. Thanks dac09.

georgeblake,
In my case, I was writing a test for a custom filter, which made use of a constant.
After specifying my constant, I injected it, for my filter to use. Like so:

    beforeEach(function() {
        module("moduleName", function($provide) {
            $provide.constant("mockConstantName", mockConstantValue);
        });
    });

    var filter;

    beforeEach(inject(function (mockConstantName, _$filter_) {
        filter = _$filter_("filterName");
    }));


    it("should return 'result' ", function () {
        expect(filter("input")).toEqual("result");
    });

Hope this helps.

@dac09 you saved my day dude 🍺
