The art of simulating a service in unit tests for an AngularAMD application

I am working on an angular application using AngularAMD with require.js. I need to simulate a service as shown below:

module(function ($provide) {
    $provide.service('ToolsService', function () {
        var toolsServiceMock = {
          someMethod: function () { }
        };
        return toolsServiceMock;
    });
});

Then, I want to inject it like this:

angularAMD.inject(function ($injector) {
    toolsService = $injector.get('ToolsService');
});

However, the $injector is returning the actual service instead of the mock. Additionally, it seems that the function($provide) is not being called.

When I switch from angularAMD.inject() to angular.inject(), I do get the mock but other parts of the application stop functioning properly.

Is there a way for me to instruct angularAMD to use mocks rather than real implementations?

If you want to test the service using angularAMD, here are some steps you can take:

define(['app','angularAMD'],function(app,angularAMD){
    'use-strict';
    describe('ToolsService',function(){
        // load the controller's module
        beforeEach(angular.mock.module('appModule'));
        var moduleToInject;
        // Initialize the controller and a mock scope
        beforeEach(function(){
            angularAMD.inject(function ('ToolsService') {

            });
        }); 
        it('should check all methods', function() {

            //code to test


        });
    });
});
