Unit Testing $routeParams in directive - angularjs

Question

I have a directive that accesses the $routeParams of the page as such:
myApp.directive("myList", function ($routeParams) {
return {
restrict: 'E',
templateUrl: 'tabs/my-list.html',
link: function (scope) {
scope.year = $routeParams.year;
}
};
});
The directive works as expected and correctly accesses the $routeParams
I am trying to test using angular-mock/jasmine. I can't figure out how to pass mock $routeParams to the directive. This is what I have:
describe('myList', function () {
var scope, compile, element, compiledDirective;
var mockParams = { 'year': 1996 };
beforeEach(function () {
module('templates', 'MyApp');
inject(function ($compile, $rootScope, $routeParams) {
compile = $compile;
scope = $rootScope.$new();
});
element = angular.element('<my-list></my-list>');
compiledDirective = compile(element)(scope);
scope.$digest();
});
it('should fill in the year', function () {
expect(scope.year).toEqual(mockParams.year);
});
});
Which obviously doesn't work because I never passed passed mockParams to the directive. Is there a way to do this?

Mock the $routeParams object mockParams using angular.extend OR do assign mockParams object directly to $routeParams. In that way $routeParams will be available before directive gets compiled.
inject(function ($compile, $rootScope, $routeParams) {
compile = $compile;
scope = $rootScope.$new();
angular.extend($routeParams, mockParams);
});
