[QUESTION] How to mock properly

Hi, i'm trying to make the library work on a angular project with test in karma framework
1. gentest seems to search for a ngentest.config.js in the current directory, not in my appdata node module folder.
2. When i generate the unit test from this class

import { Component, Input } from '@angular/core';
import { FiltreLocalStorageService } from 'src/app/service/filter-local-storage/filter-local-storage.service';
import { FiltreDataService } from 'src/app/service/filtre-data/filtre-data.service';
import { SecurityService } from 'src/app/service/security/security.service';

@Component({
selector: 'app-filtre-numero-serie',
templateUrl: './filtre-numero-serie.component.html',
styleUrls: ['./filtre-numero-serie.component.scss']
})
export class FiltreNumeroSerieComponent {

@Input() vue: string;

numeroSerie: string = ''
placeholder: string = "Numéro de série"

constructor(private filtreDataService: FiltreDataService,private storageService :FiltreLocalStorageService,private securityService : SecurityService) { }

onKeyEnter(event: any) {
this.filtreDataService.updateFilter(this.vue, { numeroSerie: this.numeroSerie.trim() });
this.securityService.logUserActivityObservable('Vue Borne, utilisation du filtre: matricule valeur ' + this.numeroSerie)
}

getNumeroSerie(){
this.filtreDataService.updateFilter(this.vue, { numeroSerie: this.numeroSerie.trim() });
}

ngOnInit(){
let filtresInStorage = this.storageService.getFiltres(this.vue)
this.numeroSerie = filtresInStorage ? filtresInStorage.numSerie : ''
this.filtreDataService.subscribeToVue(this.vue,(filtreData) => this.numeroSerie = filtreData.numeroSerie)
}

}

I got this test generate

// @ts-nocheck
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { Pipe, PipeTransform, Injectable, CUSTOM_ELEMENTS_SCHEMA, NO_ERRORS_SCHEMA, Directive, Input, Output } from '@angular/core';
import { isPlatformBrowser } from '@angular/common';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { By } from '@angular/platform-browser';
import { Observable, of as observableOf, throwError } from 'rxjs';

import { Component } from '@angular/core';
import { FiltreNumeroSerieComponent } from './filtre-numero-serie.component';
import { FiltreDataService } from 'src/app/service/filtre-data/filtre-data.service';
import { FiltreLocalStorageService } from 'src/app/service/filter-local-storage/filter-local-storage.service';
import { SecurityService } from 'src/app/service/security/security.service';

@Injectable()
class MockFiltreDataService {}

@Injectable()
class MockFiltreLocalStorageService {}

@Injectable()
class MockSecurityService {}

@Directive({ selector: '[myCustom]' })
class MyCustomDirective {
@Input() myCustom;
}

.....

Mock are not generated properly, how can i config that ?

Thanks
