Failed to instantiate module, KARMA - angularjs

Question

I've finished to implement my web site with AngularJS and now, I must make my unit test to verify the correct functioning of my functions.
I was looking for a lot of tutorial on internet but apparently, my application structure doesn't allow testing with karma and jasmin.
Let me explain, I got a site web with just one single page HTML which is linked with one controller (a file .js) I've never installed Angular with NPM but I've imported it with:
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
And I load my controller with:
<script src="main.js"></script>
and some other imported script.
I would like to try my controller with unit tests, so I've created a package.json file and installed karma, jasmine, and karma-cli with npm.
I've make a folder called "Tests" and created a test.js file:
describe("App",() =>{ //Describe object type
beforeEach(module('App')); //Load module
describe('Ctrl',()=>{
var Ctrl;
beforeEach(inject( ($injector)=>{ //instantiate controller using $controller service
$rootScope = $injector.get('$rootScope');
$controller = $injector.get('$controller');
$scope = $rootScope.$new();
}));
beforeEach(inject(($controller)=>{
Ctrl = $controller("Ctrl");
}));
it("Should say hello",()=>{
expect(Ctrl.msg).toBe("Hello");
})
})
})
But when I use:
karma start
it's doesn't detect my controller.
Here is my console output:
Here is my karma.conf.js:
// Karma configuration
// Generated on Thu Jun 14 2018 16:51:15 GMT+0200 (Paris, Madrid (heure d’été))
module.exports = function(config) {
config.set({

basePath: '',
// frameworks to use

colors: true,

logLevel: config.LOG_INFO,
// enable / disable watching file and executing tests whenever any file changes
autoWatch: true,
// start these browsers
// available browser launchers: https://npmjs.org/browse/keyword/karma-launcher
browsers: ['Chrome'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false,
// Concurrency level
// how many browser should be started simultaneous
concurrency: Infinity
})
}
And how i declare my controller :
var app = angular.module('App', ['ngMaterial', 'ngMessages'])
app.controller('Ctrl', ['$rootScope', '$scope','$http','$timeout','$mdDialog','Global', 'projects', 'screens', 'users', 'licenses', function($rootScope, $scope, $http, $timeout, $mdDialog,Global, projects, screens, users, licenses) {
...
}
Here is my tree folder :
-Root
|---node_modules
|---Tests
| |---test.js
|---Scripts
|---index.html
|---main.js <--- controller of my index.html
|---style.css
|---someFactory.js
I don't think I'm doing it in the right way. Please, explain me how to do it.
