Providing “entryComponents” for a TestBed

Question

I have a component which receives a component class of component to dynamically create as a child.

let componentFactory = this.componentFactoryResolver.resolveC

Okay, I figured it out. In the test you should define new module where you declare your mock component and specify it as an entryComponent too.

@NgModule({
  declarations: [TestComponent],
  entryComponents: [
    TestComponent,
  ]
})
class TestModule {}

And import it into TestBed

TestBed
  .configureTestingModule({
    declarations: [ValueComponent, TestHostComponent],
    imports: [TestModule],
  });

I hope it will help someone :]
