Test pipe with dependencies on services

Question

I have a pipe that sanatises HTML as below:

import { Pipe, PipeTransform } from \'@angular/core\';
import { DomSanitizer } from \'@angular/platform-browser\';

@         


        

Answer 1

just in case anyone would like to reuse the constructor of the Pipe, you can use the TestBed to acheive the same result :

  let pipe: SafeHtmlPipe;
  let sanitized: DomSanitizer

  beforeEach(async() => {
    TestBed.configureTestingModule({
      providers: [DomSanitizer]
    });
    sanitized = TestBed.get(DomSanitizer);
    pipe = new SafeHtmlPipe(sanitized);
  });

  it('create an instance', () => {
    expect(pipe).toBeTruthy();
  });
