How to test sub modules using karma and mocks?

Question

Angular

I have app module and app.chat submodule

angular
        .module('app', [
            'app.chat',
        ]);

I can get the app module through tests

beforeEach(function () {
    module('app')
  });

  beforeEach(inject(function($controller) {
    vm = $controller('IndexController', {$scope: {}});
  }));

But when I want to test app.chat, the inject just doesn't work.

beforeEach(function () {
    module('app.chat')
  });

  var vm;

  beforeEach(inject(function($controller) {
    vm = $controller('ChatController', {$scope: {}});
  }));

I will be glad to answer
thanks

Check the karma config, if the problem persists - show the config and the file where the app.chat module is initialized.
