Mocking `window.location.reload` in unit tests - "Looks like your tests triggered a full page refresh!"

In one of my controllers, I have the following code snippet:

   $scope.foo = function(){
      return RolesService.remove({
        data: role
      })
      .then(function (v) {
        if (!(v && v.cdtError)) {
          $window.location.reload();
        }
      });
    }

I have injected $window into the controller.

Within my unit test, I tried to create a stub for window.location.reload using the following code:

 let $window = {location: {reload: sinon.spy()}};

  module(function ($provide) {
    $provide.value('$window', $window);
    $window.onbeforeunload = sinon.spy();
  });

However, the stub doesn't seem to be effective as I continue to encounter this error message:

Some of your tests did a full page reload!

How can I properly stub window.location.reload to prevent this from happening?

I have looked at some discussions on the Karma Github issue tracker regarding this problem, but I haven't found a satisfactory solution yet.

Answer №1

This solution appeared to be effective:

beforeEach(function(){
    angular.mock.module('app', function ($provide) {
      let $window = {location: {reload: sinon.spy()}};
      $provide.value('$window', $window);
      $window.onbeforeunload = sinon.spy();
    });
  });
