how to mock a scope from a directive instead of a controller in angular unit-test

Does that help so i am familiar with the concept of mocking a $scope and controller with a $controller constructor , The way I set up directive-specs is
beforeEach(inject(function($rootScope, $compile) {
    var htmlString = '' +
        '<my-directive some-attr="value">' +
        '</my-directive>'
        ;
    element = angular.element(htmlString)
    scope = $rootScope.$new();
    $compile(element)(scope);
    scope.$digest();
}));

wish help you to fix your issue You can create mocks in module configuration block by using $controllerProvider.register() for controllers, $provide.provider(), $provide.factory(), $provide.service() and $provide.value() for providers, factories and services:
JavaScript
beforeEach(function () {
    module('App.Directives.BreadCrumbs', function($provide, $controllerProvider) {
        $controllerProvider.register('BreadCrumbsController', function($scope) {
            // Controller Mock
        });
        $provide.factory('someService', function() {
            // Service/Factory Mock
            return {
                doSomething: function() {}
            }
        });
    });
});

How to Unit Test Angular with Jasmine Controller inside a Directive

may help you . You have to initialize and inject your controller as well. Something like this:
var $controller;
var $rootScope;

var scope;
var controller;

beforeEach(inject(function (_$controller_, _$rootScope_) {

    $controller = _$controller_;
    $rootScope = _$rootScope_;

    scope = $rootScope.$new();
    controller = $controller('ScopeController', { '$scope': scope });
}));

I wish this helpful for you I eventually figured out how to trigger the route change using $route.reload()
From the docs, it:
describe('sidebar directive', function () {
  var $compile,
    $rootScope,
    $route,
    $location,
    scope,
    element;

  beforeEach(module('MyApp'));
  beforeEach(module('my.templates')); // ng-html2js karma template loader

  beforeEach(inject(function(_$compile_, _$rootScope_, _$route_, _$location_){
    $compile = _$compile_;
    $rootScope = _$rootScope_;
    $location = _$location_;
    $route = _$route_;
    scope = $rootScope.$new();
    element = $compile("<sidebar></sidebar>")(scope);
  }));


  it('defaults to /about route', function() {
    $route.reload();
    $rootScope.$digest();
    var linkScope = element.children().scope(); // Get directive's isolated scope
    expect(linkScope.activeNav).toBe('/about');
  });

  it('sets activeNave to correct route on change', function() {
    $location.path('/foo');
    $route.reload();
    $rootScope.$digest();
    var linkScope = element.children().scope();
    expect(linkScope.activeNav).toBe('/foo');
  });
});
