I am trying to run the basic angular test that angular makes when creating a component, but they keep on failing, and i cannot find why or how to fix it.
These are the tests i am trying to run:
it('should create the app', () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.componentInstance;
expect(app).toBeTruthy();
});
it(`should have the 'FlinkRegi' title`, () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.componentInstance;
expect(app.title).toEqual('FlinkRegi');
});
it('should render title', () => {
const fixture = TestBed.createComponent(AppComponent);
fixture.detectChanges();
const compiled = fixture.nativeElement as HTMLElement;
expect(compiled.querySelector('h1')?.textContent).toContain('Hello, FlinkRegi');
});
My full App.component.spec.ts:
import { TestBed } from '@angular/core/testing';
import { AppComponent } from './app.component';
import { provideRouter } from '@angular/router';
import { provideAnimations } from '@angular/platform-browser/animations';
import { MatListModule } from '@angular/material/list';
import { MatSidenavModule } from '@angular/material/sidenav';
import { RouterOutlet, RouterLink } from '@angular/router';
describe('AppComponent', () => {
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [
AppComponent, // Import the standalone component directly
MatSidenavModule,
MatListModule,
RouterOutlet,
RouterLink
],
providers: [
provideAnimations(),
provideRouter([]), // Provide router with empty routes if not required
]
}).compileComponents();
});
it('should create the app', () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.componentInstance;
expect(app).toBeTruthy();
});
it(`should have the 'FlinkRegi' title`, () => {
const fixture = TestBed.createComponent(AppComponent);
const app = fixture.componentInstance;
expect(app.title).toEqual('FlinkRegi');
});
it('should render title', () => {
const fixture = TestBed.createComponent(AppComponent);
fixture.detectChanges();
const compiled = fixture.nativeElement as HTMLElement;
expect(compiled.querySelector('h1')?.textContent).toContain('Hello, FlinkRegi');
});
});
App.component.ts:
import { Component } from '@angular/core';
import { RouterOutlet, RouterLink } from '@angular/router';
import { MatListModule } from '@angular/material/list';
import { MatSidenavModule } from '@angular/material/sidenav';
import { provideAnimations } from '@angular/platform-browser/animations';
@Component({
selector: 'app-root',
standalone: true,
imports: [RouterOutlet, MatSidenavModule, MatListModule, RouterLink, provideAnimations()],
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'FlinkRegi';
}
The errors i get: AppComponent > should render title Error: The "[object Object]" type, imported from "AppComponent", must be a standalone component / directive / pipe or an NgModule. Did you forget to add the required @Component / @Directive / @Pipe or @NgModule annotation?
AppComponent > should create the app Error: The "[object Object]" type, imported from "AppComponent", must be a standalone component / directive / pipe or an NgModule. Did you forget to add the required @Component / @Directive / @Pipe or @NgModule annotation?

I have no idea what the problem can be. i have no idea what the [object Object] is refering to, and i ried nearly any solution i could find.
You added provideAnimations()
in your AppComponent
imports
. It seems to me that's the cause of your problem, because if I remove it in my reproduction, all tests pass.
