How to Jasmine test code within angular module run block


I would like to Jasmine test that Welcome.go has been called. Welcome is an angular service.

angular.module('welcome',[])
  .run(function(Welcome) {
    Welcome.go();
  });

This is my test so far:

describe('module: welcome', function () {

  beforeEach(module('welcome'));

  var Welcome;
  beforeEach(inject(function(_Welcome_) {
    Welcome = _Welcome_;
    spyOn(Welcome, 'go');
  }));

  it('should call Welcome.go', function() {
    expect(Welcome.go).toHaveBeenCalled();
  });
});

Note:

  • welcome (lowercase w) is the module
  • Welcome (uppercase W) is the service

Solution

  • Managed to figure it out. Here is what I came up with:

    'use strict';
    
    describe('module: welcome', function () {
    
      var Welcome;
    
      beforeEach(function() {
        module('welcome', function($provide) {
          $provide.value('Welcome', {
            go: jasmine.createSpy('go')
          });
        });
    
        inject(function (_Welcome_) {
          Welcome = _Welcome_;
        })
      });
    
    
      it('should call Welcome.go on module run', function() {
        expect(Welcome.go).toHaveBeenCalled();
      });
    });
