Comparing Angular NgModule and TestBed Side by Side

TestBed’s configureTestingModule method looks similar to NgModule in usage. Check out this side by side example:

@NgModule({                        |     TestBed.configureTestingModule({
                                   |
    declarations:[                 |       declarations: [
      AppComponent,                |         AppComponent,
      CurrentResultsComponent,     |         CurrentResultsComponent,
      ResultsLogComponent          |         ResultsLogComponent
    ],                             |       ],
    imports: [                     |       imports: [
      BrowserModule,               |         FormsModule,
      FormsModule,                 |         HttpModule
      HttpModule                   |
    ],                             |       ],
    providers: [                   |       providers: [
      StockRetrieverService        |         {
    ],                             |           provide: StockRetrieverService,
                                   |           useClass: TestStockRetrieverService
                                   |         }
                                   |       ]
                                   |
                                   |
    bootstrap: [AppComponent]      |
  })                               |
  export class AppModule { }       |     });
