SpyNgModuleFactoryLoader Doesn't work anymore in angular 13/14 since NgModuleFactoryLoader is deprecated and removed from Agular .
Replace SpyNgModuleFactoryLoader with NgModule
we can use ngModule instead of it like below
it('Lazy loading test case', fakeAsync(() = {

tick();
}));

you can see the source code for the same in the below link (search for 37)

Hi thanks for sharing but (Angular 15.0.3);

This lines gives me error: `const lazyloder = TestBed.inject(NgModule);`

```sh
NullInjectorError: -> DecoratorFactory]:
NullInjectorError: No provider for DecoratorFactory!
error properties: Object({ ngTempTokenPath: null, ngTokenPath: [ 'DecoratorFactory', 'DecoratorFactory' ] })
```
