I resolved it like this:

import { FormsModule, NgForm } from '@angular/forms';
import { myComponent } from './my.component';
describe('myComponent', () => {
let component: myComponent;
let fixture: ComponentFixture<EmailInputsComponent>;
beforeEach(async(() => {
    TestBed.configureTestingModule({
        imports: [FormsModule],
        declarations: [myComponent],
        providers: [NgForm] // <- LOOK AT ME I AM A PROVIDER!!!

Update:

Angular v4.4.3 should fix the issue

Previous version:

I assume you're using angular 4.x version.

It's known issue. Wait till new angular version is published or set angular version to 4.3.6
