How to test John papa vm.model unit testing with jasmine?

Question

I use John papa angular style guide my controller looks like:

following the style John papa style controller style guide:

function testController() {         


        

Answer 1

The vm is equal to the instance itself via vm = this;

Therefore, all the properties are hanging directly off of the object.

function foo(){
  var vm = this;

  vm.name = 'Josh';
}

var myFoo = new foo();
myFoo.name; // 'Josh';

So all you need to do is change your expectations to remove the vm property.

expect(testController).toBeDefined();  
expect(testController.model).toBeDefined();     
expect(testController.model.name).toEqual("controllerAs vm test");

In order to prove this, here is your exact example, and the associated Jasmine tests.

function testController() {

  var vm = this;

  vm.model = {
    name: "controllerAs vm test"
  };
}


angular.module('myApp', [])
  .controller('testController', testController);

describe('Controller: testController', function() {

  beforeEach(module('myApp'));

  var testController;

  beforeEach(inject(function($controller) {
    scope = {};

    testController = $controller('testController', {});

  }));

  it('should have model defined and testController.model.name is equal to controllerAs vm test', function() {
    expect(testController).toBeDefined();
    expect(testController.model).toBeDefined();
    expect(testController.model.name).toEqual("controllerAs vm test");
  });

  it('should not have a property called vm', function() {
    expect(testController.vm).toBeUndefined();
  });
});
