The module 'DynamicTestModule' has imported an unexpected directive called 'InformationComponent'. To resolve this issue, please include a @NgModule annotation

Even though I found a similar solution on Stackoverflow, it didn't resolve my issue. So, let me explain my scenario. When running the ng test command, I encountered the following error:

Failed: Unexpected directive 'InformationComponent' imported by the module 'DynamicTestModule'. Please add a @NgModule annotation.
error properties: Object({ ngSyntaxError: true })
...

I've attempted various solutions but none seem to work, as I still encounter this error.

uploadcomponent.spec.ts

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

    import { UploadComponent } from './upload.component';
    ...

    describe('UploadComponent', () => {
      ...
    });

information-component.ts

import { Component, OnInit, Input, OnChanges } from '@angular/core';
import * as InformationMessages from '../../../json/InformationMessages.json';

@Component({
  selector: 'app-information',
  templateUrl: './information.component.html',
  styleUrls: ['./information.component.css']
})
export class InformationComponent implements OnInit {
  ...
}

Your assistance in resolving this would be greatly appreciated.

app.module.ts

import {BrowserModule} from '@angular/platform-browser';
import {ErrorHandler, NgModule} from '@angular/core';
...

@NgModule({
  declarations: [
    AppComponent, HomeComponent, MenuComponent, HeadComponent, ArianeComponent,
    PlanComponent, SeparatorComponent, FooterComponent, ErrorComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    BreadcrumbModule,
    HttpClientModule,
    ...
  ],
  providers: [...],
  exports: [],
  bootstrap: [AppComponent]
})
export class AppModule {
  constructor(library: FaIconLibrary) {
    library.addIcons(faArrowRight);
  }
}

Answer №1

Remember, when importing in your Angular project, you can only import modules and not components directly. Double check your *.module.ts file under the @NgModule decorator in the imports section to ensure you are not mistakenly trying to import a component like InformationComponent.
