import { ComponentFixture, TestBed } from '@angular/core/testing';

import { RouterTestingModule } from '@angular/router/testing';
import { UpdateComponent } from './update.component';
import { RouterModule } from '@angular/router';
import { HttpClientModule } from '@angular/common/http';
import { MatDialogModule, MatDialogRef, MAT_DIALOG_DATA } from '@angular/material/dialog';

describe('UpdateComponent', () => {
let component: UpdateComponent;
let fixture: ComponentFixture<UpdateComponent>;

beforeEach(async () => {
await TestBed.configureTestingModule({
declarations: [ UpdateComponent ],
providers:[
NotesServiceService,
