unit-testing - Angular 2 单元测试 : Custom Pipe error The pipe could not be found

Question

我有一个名为“myPipe”的自定义管道。我得到:

The pipe 'myPipe' could not be found error

在我的单元测试中请建议在我的 .spec.ts 中导入和声明什么

这是我的.spec.ts

import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { DebugElement } from '@angular/core';

import { MyComponent } from './main-page-carousel.component';

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

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

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

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

谢谢!

你应该能够做到这一点:

import { MyPipe } from 'here put your custom pipe path';

TestBed.configureTestingModule({
    declarations: [ MyComponentUnderTesting, MyPipe ]
})
