    var app = new Boot();
    class Service {
        public i: number = 1;
    }

    @Injectable()
    class TestClass {
        constructor(private _service: Service) {}

        public get service(): Service {
            return this._service;
        }
    }

    class ProviderTest extends ServiceProvider{
        register(app: Boot) {
            app.ioc.singleton(Service.name, Service);
            app.ioc.bind(TestClass.name, TestClass);
        }

        boot(app: Boot) {
            const service = app.get<Service>(Service);
            service.i++;
        }
    }

    // using ServicerProvider provider resource to app
    app.loader.add(ProviderTest);
    app.preload();
    var test = app.get<TestClass>(TestClass);
    expect(test.service.i).to.eql(2);

    // resolve class with inject
    var test2: TestClass = app.resolve(TestClass);
    expect(test2.service.i).to.eql(2);

    // using alias
    app.alias.add("test", "test1");
    app.ioc.bind("test1", "test_2");
    var val = app.get<string>("test");
    expect(val).to.eql("test_2");

    //
    app = new Boot();
    app.hook.on("app:preload:end", () => {
        console.log("work");
    })
    app.preload();
