Question: What is the role of the Angular TestBed?

Answer: The TestBed is an Angular testing utility that allows you to configure and create instances of Angular testing modules. It provides methods to compile components, create services, and perform other tasks needed for testing Angular applications.

  declarations: [AppComponent],
  providers: [DataService],
});
