如何修复Angular Unit Test中的“Error: No value accessor for form control with name”？

import { Component } from '@angular/core';
import { FormControl, FormGroup } from '@angular/forms';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.css']
})
export class MyComponent {
  myForm = new FormGroup({
    myControl: new FormControl('')
  });
}

<form [formGroup]="myForm">
  <input formControlName="myControl" />
</form>

import { ComponentFixture, TestBed } from '@angular/core/testing';
import { ReactiveFormsModule } from '@angular/forms';
import { MyComponent } from './my-component.component';

describe('MyComponent', () => {
  let component: MyComponent;
  let fixture: ComponentFixture<MyComponent>;

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [ MyComponent ],
      imports: [ ReactiveFormsModule ]
    })
    .compileComponents();
  });

  beforeEach(() => {
    fixture = TestBed.createComponent(MyComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

<form [formGroup]="myForm">
  <input formControlName="myControl1" />
  <input formControlName="myControl2" />
</form>
